DETAILED DESCRIPTION OF THE INVENTION

(28) Novel Acid Extraction/Bio-Fermentation Process of Nigella Sativa Seeds:

(29) In this invention, the process of extraction of the bioactive phytochemical composition from Nigella sativa seeds consists of three steps of acid extraction of NS seeds; bio-fermentation of the extract; and incubation of the extract as a continuous process that take place over a period of time ranging from few hours to 40 days and beyond up to 1 year.

(30) The solvent used for the extraction of NS seeds is Ethanoic acid (vinegar, carboxylic acid) in a range of concentration from 0.1% to 20%, preferably 1% to 5%, with or without the mother of vinegar, preferably with the mother of vinegar and incubation of the extract under aerobic or anaerobic conditions.

(31) What are the chemicals that are being extracted by the novel process of this invention?

(32) The chemical composition of Nigella sativa seeds has been extensively studied in published research. The seeds contain 20-85% of protein, 38.20% of fat, 7-94% of fiber, and 31.94% of total carbohydrates (Yimer et al., 2019).

(33) According to Forouzanfar et al., (2014) To identify the composition of the Nigella sativa (NS) seeds sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) was used. The fractionation of whole NS seeds was done which shows the bands ranged from 94 to 100 kDa molecular mass and the results are as follows:

(34) The fixed oil (32-40%) contains: unsaturated fatty acids which includes: arachidonic, eicosadienoic, linoleic, linolenic, oleic, almitoleic, palmitic, stearic and myristic acid as well as beta-sitosterol, cycloeucalenol, cycloartenol, sterol esters and sterol glucosides.

(35) The volatile oil (0.4-0.45%) contains saturated fatty acids which includes: nigellone that is the only component of the carbonyl fraction of the oil, Thymoquinone (TQ), thymohydroquinone (THQ), dithymoquinone, thymol, carvacrol, α and β-pinene, d-limonene, d-citronellol, p-cymene volatile oil of the seed also contains: p-cymene, carvacrol, t-anethole, 4—terpineol and longifolene.

(36) Total oil refers to a product that contains both fixed and volatile NS oil.

(37) NS seed have two different forms of alkaloids: isoquinoline alkaloid that includes: nigellicimine, nigellicimine n-oxide and pyrazol alkaloid that includes: nigellidine and nigellicine. As an alkaloid, Nigellidine is soluble in acid media. Hence, it can be extracted with the current method using ethanoic acid. Nigellidine have not been extracted according to google search. Alkaloids form salts with acids, and those salts are water soluble. A solution of acetic acid in ethyl acetate may, possibly, be also effective for the acid extraction of the considered alkaloid (Wiki).

(38) NS seeds also have saponin and alpha-hederin which is it is a triterpenoid saponin present in the defatted seeds of NS and is water soluble (El-Tahir and Bakeet, 2006; Wiki). Alpha-hederin have bronchiolytic pharmacologic action is related to symptoms of mucus, wheezing, shortness of breath and chest discomfort as symptoms of bronchitis or bronchial hypersensitivity and asthma. The anti-inflammatory effect of alpha-hederin is possibly through mediators synthesized by T-lymphocytes, endothelial cells through the IFN induced innate and adaptive immunity against viral and some bacterial infections (Muhammad, 2017).

(39) Total synthesis of Nigellidine is described by Khan and Afzal, 2016, and synthesis of alpha-hederin is described by Plé et al., 2004.

(40) Most of the pharmacological activity of the entire seed or their extract are mainly ascribed to its volatile oil, of which thymoquinone (2-isopropyl-5-methyl-1,4benzoquinone) is the most profuse component (Iqbal et al., 2018). Thymoquinone can be quantified using RP-HPLC and authentic standards of thymoquinone purchased from Sigma-Aldrich. One serious drawback with thymoquinone is its toxicity at high doses and poor water solubility which limit its usage as a therapeutic agent (Khan and Afzal, 2016).

(41) The nutritional compositions of NS are vitamins, carbohydrates, mineral elements, fats and proteins that include eight or nine essential amino acids. Most of the pharmacological effects are due to quinine constituent, of which TQ is the mainly abundant. TQ possess antioxidant, anti-inflammatory, antibacterial and antifungal activity (Forouzanfar et al., 2014).

(42) The seed have an intensely bitter taste due to the presence of a seed protein nigellin and bitter principle (Kalidasu et al., 2017), the oil and/or the solvent (Bornare et al., 2015).

(43) Microscopical location of the bioactive phytochemicals of NS: The grey colored albumen consisting of thin-walled cells, with several oil droplets (Margout et al., 2013). The saponin α-hederin accumulate both in the seed coats and the inner seed tissues at different ratios (Botnick et al., 2012).

(44) The most important compounds due to which medicinal value of these seeds increased are saponins, flavonoids, volatile oil. Phytochemical analysis of NS extracts is detailed by Amir et al., 2018).

(45) According to Gholamnezhad et al., 2015 Nigella sativa Chemical compounds PubChem CID is the following Thymoquinone (PubChem CID: 10281), Dithymoquinone or Nigellone (PubChem CID: 398941), Thymol (PubChem CID: 6989), Carvacrol (PubChem CID: 10364), p-Cymene (PubChem CID: 7463), 4-Terpineol (PubChem CID: 11230), Trans-anethol (PubChem CLD: 637563), Alpha-pinene (PubChem CID: 6654), Alpha-hederin (PubChem CID. 71464054), Kaempferol glucoside (PubChem CID: 12358425).

(46) Material and Methods

(47) Materials Used 1—In the acid extraction process of this invention carboxylic acids are used because they are organic acids, week and soluble in water. Carboxylic acids contain a functional group called the carboxylic group (—COOH), with a general formula C.sub.nH.sub.2n+1COOH including 20 straight-chained saturated carboxylic acids and others (chemistry yolp website). By way of example, and for practical purposes acetic acids was selected because it is available commercially and it serves the purpose of safety for human consumption. The trivial name acetic acid is the most commonly used and preferred IUPAC name. The systematic name ethanoic acid, a valid IUPAC name, is constructed according to the substitutive nomenclature. The name acetic acid derives from acetum, the Latin word for vinegar, and is related to the word acid itself. Vinegar is an aqueous solution of acetic (ethanoic) acid and trace chemicals and flavors. Vinegar typically contains 5-8% acetic acid by volume. Usually the acetic acid is produced by the fermentation of ethanol or sugar by acetic acid bacteria. There are many types of vinegar, depending on source materials including fruit, palm, balsamic, cane, grains, spirit, white wine vinegar and the white distilled vinegar. FIG. 4A demonstrates the extraction solvent used is the commercially available raw apple cider vinegar (16), purchased from local groceries. The solvent has a concentration of ethanoic acid in water 5% acidity. The vinegar is either raw unfiltered with the “mother of vinegar” in an amount of about %-1 cubic centimeters per liter of vinegar, or it is filtered and pasteurized without a mother of vinegar. The vinegar acidity of both raw and filtered is 5% acidity as it is diluted in water. The raw apple cider vinegar used in the experiment is of 3 Trade names: Bragg, Nature Intent and Simple Truth. The filtered pasteurized apple cider vinegar is Trade named Market Pantry (17). Ethanoic acid, also known as acetic acid, is one of the carboxylic acids. Ethanoic acid is a liquid organic compound with the chemical formula CH.sub.3COOH. It is colorless with sharp acrid smell. The “mother of vinegar” that is present in the commercially available 1-liter vinegar bottle (MV) is a brownish sedimented powder about ½-1 CC.sup.3 in volume, that settles on the bottom of the container. The vinegar can be stored for months without any detectable changes, activity or multiplication of this mother of vinegar. The raw apple cider vinegar is mostly apple juice, but adding yeast turns the sugar in the juice into alcohol. This is a process called fermentation. Bacteria turn the alcohol into acetic acid. That's what gives vinegar its sour taste and strong smell, i.e., the raw unpasteurized unfiltered apple cider vinegar contains both yeast and acetic acid bacteria. 2—Nigella is a genus of 18 species of annual plants in the family Ranunculaceae, native to Middle East, South Asia, North Africa, Southern Europe and Southwest Asia. Common names applied to members of this genus are caraway, Nigella, black seed and black cumin, Kala Jeera, Cumin Noir. In this invention and by the way of example we will refer to Nigella sativa because it is available and is safe for human consumption. Nigella sativa (NS) is an annual flowering plant in the family Ranunculaceae. The plant grows to 20-30 cm tall, with finally divided linear leaves. The flowers are delicate, and usually colored pale blue and white. The fruit is a large and inflated capsule composed of three to seven united follicles, each containing numerous seeds which are used as a spice and folklore medicine. The genus name Nigella is a diminutive of the Latin niger (black), referring to the seed color. Any part of the plant can be extracted for its bioactive phytochemicals of this invention, preferably the seeds of Nigella sativa. Nigella sativa L. is classified by the United States Department of Agriculture (USDA) in the buttercup family—Ranunculaceae, genus Nigella L. and species Nigella sativa L.—Black cumin. Pharmaceutical Name: Semen Nigellae sativae. Other names: black caraway, Nigella, black cumin kalojeera, kalonji or kalanji, Habat al-baraka, Ketash, Schwarz kummel, and ‘Hak Jung Chou’ and many others. In the following discussion the name Nigella sativa or NS are being used alternatively. FIGS. 4A and 4B demonstrate Nigella sativa dried seeds (18) purchased from local grocery stores under the Trade name Sadaf (www.sadaf.com), Azure (www.westcoastpita.com), Al Attar Spices, Crescent, online black seed purchased under the Trade name Terrasoul Superfood, Adonis and Deep (depicted in FIG. 4B). All the NS seeds are packed in the USA. NS seeds are used without any further treatment. FIG. 5 depicts grinding sizes of NS seeds including coarsely grinded seed (19) and finely grinded seed (20) placed on a graph paper to compare the grind size to the whole seed (18) 3—Spring water (21) Trade named Crystal geyser that have a total mineral contains of 90 mg/liter, including: sodium 13 mg, potassium 2 mg, calcium 27 mg, magnesium 6 mg, sulfate 36 mg, chloride 6 mg. Distilled water can be used. 4—Nigella sativa cold-pressed oil Trade named Hemani (Kalonji, Black Seed oil) (www.haemanitrading.ae). 5—Olive oil as control

The glass jar (22) have a lid that can clamp down on foods with vulcanized rubber gaskets (23) for an airtight seal. The container and can be filled to the top (arrowed) for anaerobic bio-fermentation of NS seeds. Different sizes of glass jars were used including a large jar volume is 1 gallon and a small jar volume is 1 liter. 2—Domestic spice grinder, electric, high speed, or any grinder known in the art. 3—Glass stirring rods. 4—PH Indicator Strips Trade named Oakton with 1.0 interval. Reading on a scale on 1-14, where a PH value of a neutral solution is 7.0. Solutions with PH value below 7.0 are considered acidic.

(49) Experimental Design of Extracting Nigella sativa Seeds using Ethanoic Acid

(50) The experimental variables included in the design are: 1. Seed type: using 6 locally available NS seeds and online available seeds packed in the USA. 2. Seed grind size: including whole seed, coarse grind, fine grind, crushed seeds and powder. 3. Solvent type: using 3 locally available ethanoic acid (vinegar) either unfiltered unpasteurized with the mother of vinegar (16) or pasteurized without the mother of vinegar (17). 4. Solvent dilution: in a range from 0.1% to 20%, preferably 5%, 1.66 or 1.25% diluted in mineral spring water (21) or distilled water. 5. Seed to solvent ratio: measured as weight/volume, using a range of different ratios. 6. The availability of oxygen: with either experiments being performed in an anaerobic condition with vulcanized rubber gaskets (23) for an airtight seal or under aerobic condition. 7. Bio-fermentation of the composition: by the effect of the presence of the mother of vinegar (MV), i.e., acetic acid bacteria observed from day 1 until day 40 and beyond up to 1 year. 8. The effect of incubation time on the composition: starting from few hours, to few weeks, to 40 days up to 1 year.

(51) Why Selecting Ethanoic Acid?

(52) There are several unique features of ethanoic acid as a solvent over prior art solvents. Theoretically speaking, ethanoic acid can produce different effects, not simple extraction, for example, but not limited to: a. Ethanoic acid is a powerful polar solvent, although it is considered as a weak acid, but actually ethanoic acid is still a powerful polar organic solvent, that dissociates about 10{circumflex over ( )}11 times more than ethanol, and is stronger than methanol. b. Commercially available ethanoic acid in vinegar is diluted in water (5% acidity), therefore it has the advantage of an aqueous extraction in acid medium. Aqueous solution id ideal to dissolve the saponin alpha-hederin from NS seeds c. Commercially available ethanoic acid (vinegar) (16) contains Acetobacter aceti (mother of vinegar) (MV) that will produce a bio-fermentation process during the incubation of the composition. d. Ethanoic acid can expand and loosen the plant cell wall cellulose for a better extraction of intracellular phytochemicals. e. Ethanoic acid is a safe solvent for human consumption; there is no need to use excessive heat to remove it, that could have a deleterious impact on the composition. f. Ethanoic acid does not leave undesirable smell or taste in the composition. g. Ethanoic acid does not extract the undesirable black pigment. h. Vinegar act as a preservative for the composition that keep it stable for long time.

(53) Step-by-Step Acid Extraction; Bio-Fermentation; and Incubation of Nigella sativa Seed of this Invention

(54) The steps for the preparation of NS extract in acid solvent and bio-fermentation of the extract include: select the type of NS seeds and vinegar as the starting material; grinding the seed; place the NS seeds in a container; soak NS seeds in ethanoic acid solvent for few hours; fill up the container with either ethanoic acid or water (21) to reach the desired acidity % of the composition; close the container under either anaerobic or aerobic conditions; incubate the composition at room temperature under either daylight or dark room; produce a composition ready for use as a therapeutic agent either within few hours or after incubation over days, weeks up to 40 days and beyond up to 1 year to allow time for the bio-fermentation process.

(55) FIGS. 4A-4B demonstrate the 2 starting materials: First, a solvent ethanoic acid present in apple cider vinegar solutions 5% acidity with the mother of vinegar that is raw unpasteurized and unfiltered (16) or pasteurized without the mother of vinegar (17). Second, Nigella sativa Linn dry herbal seeds (18).

(56) FIG. 5 demonstrates whole NS seeds (18) coarse grinded NS seeds (19) and fine grinded NS seeds (20) used in this process.

(57) Grinding Nigella dried seeds: A small electric coffee grinder was used to chop up the NS seeds (18). Small batches of the seed were grinded, approximately 50 grams each time.

(58) Fine grind: For the fine grind, the Nigella seeds were chopped up for 20 seconds (19).

(59) Coarse grind: For the coarse grind, the Nigella seeds were chopped up for 10-15 seconds (20).

(60) Powdered NS seed: For the powder, the Nigella seeds were chopped up for 30 seconds.

(61) The time between grinding and the use of the seed is variable. Crushed or flaked NS seed can also be used.

(62) FIG. 7 demonstrate soaking NS seeds: Place 200-grams of grinded NS seeds in 1—liter glass container (22); add ½ liter of 5% ethanoic acid with the mother of vinegar (16); mix the content manually using a glass stirring rod. The grinded seeds are left to soak in the solvent for 2-8 hours preferably 4-hour period at room temperature. During the soaking time, the contents are mixed manually 4-8 times, using a glass stirring rod until the seed absorb almost all the solvent.

(63) After the NS seeds absorb most of the solvent, “fill up” the container to the top by adding ethanoic acid 5%. The final concentration of the solvent is 5% acidity. Close the container airtight with its lid that contains the rubber vulcanized gasket (23) to generate an anaerobic environment.

(64) Incubate the mixture at room temperature either in daylight or in dark room.

(65) The composition is incubated over a period of either 8-24 hours, or few days up to 40 days and beyond up to 1 year.

(90) Experimental Results:

(91) Changes in the Physical Properties

(92) Experimental Results of Acid Extraction/bio-fermentation process of Nigella sativa Seed

(93) The results of extracting the bioactive phytochemical composition from NS seeds using ethanoic acid in different concentrations with or without the mother of vinegar (MV) have been described under FIGS. 8-16; detailed in table 2. Most of the physiochemical properties of the bioactive phytochemical composition of NS in ethanoic acid were assessed by visual observations. The immediate changes in the physical properties of the novel composition as compared to the starting materials (solvent and the NS seed) was observed and recorded during the first day of mixing. Later, the gradual changes of the physical properties in the resultant composition were observed and recorded on daily and weekly intervals. The physiochemical properties of the composition are described under the following topics: A—The effect of different variables on the outcomes, the most significant variables are: Ethanoic acid concentration (% acidity), wherein an acidity of 5% resulted in an opaque pale-yellow emulsion. the light is absorbed, and is not allowed to pass by the particles present in the solution including water miscible oil, protein, cell structure and other particles as depicted in FIGS. 14A and 14B. On the other hand, an acidity less than 5% resulted in a honey-colored, clear, homogeneous mixture that contains many solutes extracted from NS bioactive phytochemicals in ethanoic acid as a solvent, the composition is only of one phase, no black pigment is extracted into this composition, the composition is optically transparent, allowing much of the day light that falls on them to be transmitted through the material with a brilliant shining color as depicted in FIG. 9. NS seed grind size, wherein the finer the grind size the higher the concentration of the composition as judged by the depth of the color, and a thicker emulsion obtained. Availability of oxygen for bio-fermentation, wherein an airtight container with a vulcanized rubber gasket produce either no or minimal new NS mother (24 of FIGS. 11 and 15)) formation while availability of oxygen, even to the minimum amount allows the development of thick (0.1-5 cm thick), multi-layered new NS mother as shown in FIG. 11 (24). The presence of the mother of vinegar (FIGS. 11 and 15) that initiate a “dynamic” process of fermentation and all the subsequent changes in the composition and the formation of new NS mother that can be used as a complimentary therapy versus the absence of the mother of vinegar that resulted in a “static” acid extraction on NS seeds. The seed/solvent ratio affect the concentration of the solutes within the composition and is visualized by the depth of the honey-colored extract; the higher the ratio the deeper the color. The seed and solvent type also affect the resultant composition, as some seed have higher extraction of oil and some seeds flocculate heavier than the others in concentrated solvent. The duration of incubation is vital factor that allows for the effect of bio-fermentation and for the changes that results herewith. B—Timewise observations on the outcomes of mixing NS and ethanoic acid: Immediate results, that are seen within few hours of mixing, wherein, the composition is classified into either clear, honey-colored composition (FIG. 9, 11) or an opaque, milky pale-yellow colored composition (FIG. 14A, 14B, 15). This immediate result is believed to be dependent on the % acidity of the solvent. It is noticeable that the composition consists of a solute that is completely dispersed throughout the solvent. The total volume of the mixture in the jar is fixed. The composition resulted from extraction of NS seeds using ethanoic acid solvent is very much different than the starting material. Delayed onset result that are the outcomes of bio-fermentations including the liberation of gas bubbles and the formation of a new NS mother (24) that are seen within few days up to 40 days and beyond up to 1 year indicating the activity of bio-fermentation that is continuously going-on within the composition. Wherein gas bubbles are either continuously produced and can be seen whenever the jar is moved as depicted in FIG. 17 (27) over period of 4-7 weeks or at the time of soaking the seeds. Wherein, thick multi-layered new NS mother (24) is formed as seen in FIG. 11 and at the top of the composition or on the mouth of the container as seen in FIG. 18A (24). In the anaerobic container a thin new NS mother is formed as seen in FIG. 18B (24). Bio-fermentation is linked to the availability of oxygen and it results in the formation of a new thick new NS mother; this indicate that the composition keeps the acetic acid bacteria viable, provide the necessary food and oxygen for multiplication. will have effective bioactive phytochemical ingredients such as those discussed in the prior art. The “mother” is described as molecules of organic acids and enzymes connected in strand-like chains” that contain acetic acid bacteria (Acetobacter aceti). Stability over-time of the composition, wherein, incubating the composition for 40 days and beyond up to 1 year at room temperature and day light make no changes in the physical characteristics of the composition including color, clarity and opacity, aroma, taste and preservation. Layering of the composition as time passes, in addition to the black pulp on the bottom, and the composition appears to have two liquid phases with different color and different opacity. is happening over time as a result of precipitation, fermentation and conversion. Two new layers are being formed a white layer and a transparent layer. Wherein, the white layer seen in FIG. 15 (26) is present in almost all the jars, formed within 7-12 days, which is about 1-cm thick that is formed when the fine particles (Grinded NS or mother) floating in the suspension settles down. Wherein, the transparent layer is described as “zone of transformation” from opaque to semi-opaque phase as seen in FIGS. 21 and 20 (28), wherein, the lowest part of the composition that lies in contact with the white layer (26) make a dramatic change; allowing light to pass through and changes its phase, appearance, and character in this particular location of the composition. wherein, this change in the liquid phase is possibly due to a bio-fermentation process! C—Reproducibility of the type of the composition: reproducible results refers to changes in the physical properties that are capable of close imitation of each other, can be made again each time in different experiments in multiple containers where the solvent and NS seeds were treated as in the flow chart. Wherein, several compositions are prepared under identical ethanoic acid concentration, grind size of NS seeds and oxygen availability produce similar physical characteristics of their composition. FIG. 19 demonstrate coarsely grinded NS seed extracted with 1.25-1.66% acidity, and FIGS. 20 and 15 demonstrate finely grinded NS seed extracted with ethanoic acid 5% acidity. D—Pure compounds extracted from NS composition by this novel method that have never been part of the prior art. The pure compounds can be chemically characterized, quantified and studied for safety and efficacy for use in pharmaceutical preparation: A. Novel white solid precipitate depicted in FIG. 20 (29) that is formed in the jar referred to as example #2 of FIG. 10. Crystallization indicates that the composition reaches a saturation point in relation to one constituent. At this point, a process of precipitation is occurring at the mouth of the container with the formation of a white precipitate sticking to the rubber topper and the glass rim. The taste of this which precipitate is neutral. Precipitation occurs at room temperature. Possible components of NS composition in acid solvent are either alpha-hederin or Nigellidine alkaloid or others. B. Novel water-miscible (mixable) NS oil in the composition (30) which is a lighter clearer oil, wherein, the NS seed oil that forms 30-40% of the seed content is not forming a defined layer floating above the aqueous composition of the bio-fermentation jar. It is rather dispersed in the acid-aqueous phase of the composition. The water-miscible oil (30) can be felt and shines on the cover of the jars depicted in FIG. 23A, when placed on the fingertip as depicted in FIG. 23B, when the composition is evaporated, it leaves the NS water-miscible oil (30) behind as depicted in FIG. 32C and as small dispersed droplets on a glass surface depicted in FIG. 23D. This water miscible oil is thin easily washed away. C. Pure novel white crystal-like oil droplets (32) are formed when commercially available NS oil (31) is mixed with ethanoic acid 5% acidity (16) and incubated. The oil droplets are 1-3 millimeters in diameter are moving down into the polar solvent and are not mixable with the solvent. The oil droplets are adherent to the inner glass surface of the container and are scattered as depicted in FIG. 23F. As the droplets grows bigger they settle to the bottom of the container as depicted in FIG. 23G. As a control experiment, olive oil was mixed with vinegar (16), no observable oil droplets were seen. When the NS commercial oil and ethanoic acid solvent are mixed manually for 15-30 minutes a caramel colored emulsion is formed and the crystal-like oil drops appears within the first 30-minutes. Possible components of NS composition that is extracted is the thymoquinone volatile oil or another component. D. Thick multi-layered new NS mother (24). E. Floaters that are formed in the composition during the incubation period in both the clear composition and the emulsion (34) (FIGS. 24A and 24B) F. Sticky viscous component that is felt when the composition is concentrated. G. Bitter component that can be tested when the composition is concentrated. H. Mucilage (33) seen in FIG. 21. I. Novel component specifically formed during the acid extraction/bio-fermentation process that can be chemically characterized and are unknown in the prior art. E—Changes in the volatile oil aroma, wherein the strong acidic stringent aroma of the vinegar and strong NS aroma of the grinded seed become very mild and neutral immediately. F—Change in the bitter spicy taste of the NS seeds and the acidic vinegar to a milder neutral palatable test.

(94) Mechanisms of the Formation and Stabilization of NS Emulsion Composition

(95) As obvious with other herbal medicines, the extraction methods influence the chemical composition, and consequently, the pharmaceutical activity of a specific NS preparation (Khan and Afzel, 2016).

(96) The NS seed emulsion in ethanoic acid 5% is depicted in FIGS. 10, 14, 15, 20 and 21 and is explained in experiments #2, 4 and 5.

(97) NS emulsion composition consists of two liquids ethanoic acid solvent and NS oil in a mixture that is stable for weeks and months.

(98) I would hypothesize that the extracted composition is both an emulsion and a suspension.

(99) The suspension may refer to fine solid particles floating in the liquid remains dispersed in this thick emulsifies oil-in-liquid extract which make it less clear than pure ethanoic acid solvent.

(100) The emulsion may refer to oil that is suspended in solution.

(101) The solution further comprises oils that are dissolvable in acidic medium of ethanolic acid. The degree of emulsification also affects the color/clarity of the solution. The opacity of the solution increases more insoluble oils are emulsified making the solution have a color that is more milky than marketed ethanolic acid (vinegar) and samples that have suspended solids and dissolved solids. Soluble oils are oils that are extracted from NS and dissolve in the ethanolic acid or the aqueous solution.

(102) The stability of the emulsion can be explained on the following physical/chemical mechanisms: 1—The composition has a high viscosity that is attributed to the presence of the water miscible oil; 2—The Extraction/bio-fermentation of an esterified oil that is water soluble. Esterification is the result of combination of a fatty acid with an alcohol, even ethanoic acid (as a carboxylic acid) can be esterified! It is known that Linn seed oil can be esterified to become water soluble and then used in water paints. 3—Alpha-hederin is a saponin and when it is extracted in the NS composition of this invention can act as stabilizer for NS emulsion extracted by ethanoic acid.

(103) Conversion/Transformation of NS Composition

(104) Some samples appear to have two liquid phases in that have different colors or different opacity. The two-phase liquid system may result from the presence of water in the vinegar which may cause a separation of an aqueous phase in another phase that maybe the vinegar insoluble droplets or oils that are initially dispersed or emulsified in the solution start to agglomerate and form a second and distinguishable liquid phase below the solution. It can be speculated that an oil rich phase comprising vinegar insoluble forms as a separate and independent second liquid phase below the solution that make a thorough or dramatic change in the form, appearance, or character of the product of a transformation.

(105) Gas is liberated from fermentation, both aerobic and anaerobic. which gas? depends on the type of fermentation happening. Gas is liberated from fermentation of sugars and carbohydrates present in NS seeds, both aerobic and anaerobic, it could be CO2 or CO or methane or hydrogen . . . based on the type of fermentation happening, it might be making alcohols too like ethanol or butanol.

(106) It must be noted and appreciated that the instant Invention has been discussed and described in terms of theoretical and experimental aspects to emphasize practical and enabling details. However, our process(s) and product(s) comprise a complex and dynamic bio-organic environment that further includes and comprises: diffusion of liquids (water and acid) into the particles to extract solubles, diffusion of insoluble liquids into the acid/water solvent, agglomeration of insoluble liquid drops to from emulsion into the acid/water phase, dissolution of solubles into acid water, agglomeration of acid/water insoluble to form a second liquid phase that is partially or completely Immiscible with the acid/water phase, aerobic fermentation that may or may not occur concurrently with extraction of oxygen from the solution of vinegar and water to provide oxygen for the aerobic fermentation of carbohydrates, and/or anaerobic fermentation.

(107) In conclusion, broader chemical and biochemical interactions are occurring which allows one of ordinary skill in the art to describe and/or characterize the instant process(s) and product(s) in terms of reaction kinetics, thermodynamic equilibriums, and/or mass transfer rates or limitations. In one aspect, the instant invention comprises reaction kinetic, thermodynamic, and mass transfer characterization of the disclosed process(s) and product(s). Furthermore, chemical identity/structure identification and/or characterizations are also included within the scope of the instant invention.

(114) Advantages of Ethanoic Acid Extraction/Bio-Fermentation of Nigella sativa Seed Over Current Solvents

(115) In conclusion, this novel process of extracting the bioactive phytochemical constituents from NS seeds using acid extraction/bio-fermentation have demonstrated multiple advantages over existing processes.

(173) Expected Onset of Therapeutic Action

(174) The importance of the onset of INF responses relative to virus replication is vital is key factor in determines coronavirus outcomes:

(175) The current inventor in previous patent, treating virus-induced asthma exacerbations and allergic rhinitis with Nigella sativa or AM3, have found that the onset of clinical improvement in cough, sputum and shortness of breath of Nigella sativa or AM3 started in day 3 ((UK patent publication #GB2348139, granted in 2004, PCT, and U.S. Pat. No. 7,592,327, B2).

(176) According to Salem and Hossain. 2000; Forouzanfar et al., 2014, treatment of murine cytomegalovirus (CMV) infection with intraperitoneal NS oil for 7 days strikingly inhibited the virus titers in spleen and liver on day 3 of infection. This coincided with an increase in serum level of IFN-gamma. On day 10 of infection, the virus titer was undetectable in spleen and liver. increased numbers of CD4+ helper T cells.

(177) The importance of the onset of INF responses relative to virus replication is vital is key factor in determines coronavirus outcomes; INF-1 administration within 1 day after infection (before virus titer peak) protected mice from lethal SARS-CoV infection. If present early and properly localized, IFN-1 can effectively limit CoV infection (Channappanavar et al., 2019). Differences in the dynamics of interferon-related innate immune responses in children, adults and elderly may explain the reported difference in fatality rates; earlier induction of interferons in children could be the reason behind zero fatality (Nezhad et al., 2020). An early burst of type I IFN leads to protection. In contrast, a delay in IFN production causes an inability to control viral replication, leading to cellular damage and cytokine storm. The delay in response often predominates in older adults making them more susceptible to emerging infections Nikolich-Zugich et al., 2020. Interferons orchestrate local and systemic antiviral state (Denney and Ho, 2018).

(178) Assessment of Beneficial Outcomes

(179) Clinical Primary Endpoints:

(180) There are general endpoints that are used in ongoing clinical trials, e.g., Honey & Nigella sativa Trial Against COVID-19 (HNS-COVID-PK); Clinicatrials.gov Identifier: NCT04347382. Investigators will follow up with participants every 4th day to access clinically the severity of symptoms along with RT-PCR and HRCT chest or X-ray to access the disease progression. Those positive on 8th day will be followed up further for monitoring of primary end points. Findings of this trial are expected to help establishing a new remedy for the treatment of this pandemic giving mortality benefit along with earlier decrease in viral load and lesser complications rate caused by SARS-Cov-2 virus. Other clinical and laboratory endpoints known in the art can be used.

(181) Specific laboratory endpoints in vivo and in vitro: A—Interferon serum level measurement performed using patient's blood samples B—Complete blood count to demonstrate reversal of the lymphopenia C—Flow cytometry can be conducted to detect the number of specific cell type of the innate immune cells in patient's blood samples D—Viral RNA level using polymerase chain reaction (PCR). E—Activation status of natural killer cells as an early responder to virus infection and their level is significantly reduced in the lung of COVID-19 patients (Duijf P., 2020). F—The composition can be studied for activation status of natural killer cells (described by Grudzien and Rapak, 2018) or maturation of dendritic cells and the inhibition of viral replication in cell line known in the art.

(182) Nigella sativa Safety for Human Use

(183) The safety of Nigella sativa is based on the Code of Federal Regulation (CFR21) and published studies (Aftab et al, 2013; Barakat et al, 2013 and Yimer et al., 2019).

(190) The combination is speculated to prove effective either in an additive manner, or a synergistic manner, or as a booster to the immunomodulatory therapeutic effects of this invention in the treatment or prevention of COVID-19 illness.

(191) As part of the patent filed by the current inventor in 1999 (U.S. Pat. No. 7,592,327) AM3 was selected because it is an immunomodulator that induce interferon production, activate NK, and induce DCs maturation. AM3 is described in the Martindale Extended Pharmacopeia). AM3 is known as glycophosphopeptical marketed by Industrial Farmaceutica Cantabria. Also known as glicofosfopeptical, polysubstituted polycarboxylic phosphamide biopolymers or GPP and produced by Industria Farmaceutica Andromaco. The difference in the method of use of AM3 in the prior vs. the current use is that AM3 was used continuously for periods of months vs. in the current invention AM3 combination with extracts of the current invention is preferably used for a short duration of days or 2-3 weeks. In one embodiment, the instant Nigella sativa product can be used in combination with glycophosphopeptical (AM3). The disclosure of US patent (U.S. Pat. No. 7,592,327, B2) is considered relevant and is incorporated herein in its entirety. The combination is speculated to prove effective either in an additive manner, or a synergistic manner, or as a booster to the immunomodulatory therapeutic effects of this invention in the treatment or prevention of COVID-19 illness.
