A method of obtaining vitamin D from shiitake includes a) adding ethanol to shiitake powder, followed by reflux extraction, to prepare a shiitake extract; and (b) irradiating ultraviolet (UV) light to the shiitake extract prepared in step (a). When shiitake extracts are obtained and exposed to ultraviolet light under specific conditions, the content of vitamin D2 in the shiitake extracts may be increased.

Disclosed herein are embodiments of cannabis extraction methods, apparatuses for extracting cannabis, and methods of using cannabis extracts.

The present invention relates to the field of herbal compositions. In particular, the present invention is directed to an Improved Herbal Extract Composition comprising a Melissa species extract, an Avena species extract, a Tilia species extract and a unique blend of citrus components. The composition can further comprise at least one additional extract of a plant such as Citrus species, Crataegus species, Panax species, and Lavendula species. The herbal extract composition is useful in numerous ingestible forms including an extract concentrate for food and beverage preparation, additive or enhancer for existing foods and beverages and particularly in the form of a pleasant tasting and soothing beverage.

Provided are: a citrus seed extract-containing composition, a food and a drug all of which sufficiently exert a novel function of a citrus (specifically, a citrus seed extract), and a method for producing the citrus seed extract-containing composition. The citrus seed extract-containing composition includes obacunone and nomilin both derived from a citrus seed extract. Herein, the ratio of the obacunone content to the nomilin content (i.e., obacunone content/nomilin content) is at least 0.020.

A method and system of and for extraction or removal of phytochemicals from plants, including those of the plant family Cannabaceae sensu stricto. More specifically, a method and system for extracting essential oils from plants, such as cannabis, without the use of a solvent.

The invention discloses a method for extracting high-purity asarinin and use thereof. The method comprises: putting crude asarum powder in an SFE-CO.sub.2 device; under the conditions that an extraction kettle has a pressure of 30-40 Mpa and a temperature of 45-70° C., separating kettles I and II have a pressure of 5-10 Mpa, a temperature of 30-50° C. and the flow rate of CO.sub.2 is 35-60 L/h, extracting for 60-240 min to obtain total volatile oil of asarum; standing the total volatile oil of asarum for 24-72 h at a low temperature, and carrying out suction filtration under reduced pressure to obtain crude asarinin; and re-crystallizing the crude asarinin in absolute ethanol twice to obtain pure asarinin. It is found for the first time that asarinin has a good cough-relieving activity and thus can be used in preparing medicines for treating various types of coughs.

A method of treating neurological condition in a subject by administration of a pharmaceutical composition that excludes cardiac glycoside and excludes polysaccharide obtained from Nerium species or Thevetia species. Alzheimer's disease, Huntington's disease or stroke are treated by administering a therapeutically effective amount of the pharmaceutical composition to a subject.

A method of making triterpenoids from petri dish cultured Antrodia cinnamomea includes: A. providing petri dish cultured Antrodia cinnamomea in an extracting container; B. providing a supercritical solvent to the extracting container to obtain an Antrodia cinnamomea extract; sending the Antrodia cinnamomea extract to a chromatographic column to separate impurities and triterpenoids from the Antrodia cinnamomea extract, and removing the impurities, and collecting the triterpenoids containing fraction; and C. testing the bioactivity of the triterpenoids containing fraction by cytotoxicity test, cell morphology analysis, cell cycle and apoptosis test, and cell motility test to find an anti-cancer effect of the triterpenoids.

New extracts of Nannochloropsis sp. and related species of Nannochloropsis are suggested, obtainable by treating said microalgae with a solvent selected from the group consisting of C.sub.1-C.sub.1 aliphatic alcohols, ethyl acetate, water or their mixtures, removing the dissolved extracts from the residues and recovering the pure extracts from the solvent. The extracts show excellent properties particularly in modulating the metabolism of human skin and hair follicles.

A system for producing a blended extract of cannabinoids and terpenes, which extracts terpenes using supercritical CO2, and extracts a cannabinoid concentrate from the residual material using a cold ethanol flush followed by distillation; the CO2-extracted terpenes are then added back to the cannabinoid concentrate in a final blending step. Blending terpenes at the end of extraction may enhance the flavor and effectiveness of the cannabinoid concentrate. By separately extracting terpenes and cannabinoids, optimal processes and parameters may be used for each step. Blending may combine terpenes and cannabinoids in any desired ratio; for example, a terpene-to-cannabinoid ratio of approximately 1:10 may be used. The ethanol used in the cold ethanol extraction of cannabinoids may be recovered and reused for subsequent batches. Cannabinoid concentrates may be redistilled multiple times to enhance their concentration, followed by terpene blending.
