An improved method for preparing persimmon leaf extract. Dried persimmon leaves are obtained and are crushed. Ethanol is added to the dried crushed persimmon leaves and ethanol extraction is used to produce a persimmon leaf extraction solution. The persimmon leaf extraction solution is introduced into a concentrator and a first concentrated solution is produced while the ethanol is recycled. The first concentrated solution is filtered to produce a filtrate. The filtrate is introduced into the concentrator to produce a second concentrated solution. The second concentrated solution is repeatedly extracted with ethyl acetate to produce a second persimmon leaf extraction solution. The second persimmon leaf extraction solution is introduced into a concentrator to produce a third concentrated solution while recycling the ethyl acetate. Vacuum drying is used to dry the third concentrated solution to produce a dried persimmon leaf extract.

The present document describes a system and a process for the extraction of several products from apple peel. There are several unit operations involved including an ultrafiltration unit, concentration unit, and a three stage counter current separator centrifuge wherein water is used as the solvent. The final products that are extracted from apple peel include pectin, syrup, fibers, as well as soluble and dried retentate fractions.

A closed loop extraction system for extracting desired components from raw plant matter and method of use is disclosed. The closed loop extraction system features a solvent source, a chill tank, a wash tank, a rinse tank, a centrifuge, and a feed tank all in fluid communication via a series of interconnected pump systems. The method of extracting the desired products from raw plant matter uses this system to perform the extraction with a reduced amount of solvent in an energy-efficient manner.

The present invention provides a solid phase extraction method using a micro device having a dam forming portion including a dam, the solid phase extraction method comprising the steps of: (i) injecting a solvent and a filler into the micro device, moving the solvent to the dam forming portion, the dam allowing the solvent to flow therethrough and preventing the filler from passing therethrough, and adsorbing a material to be separated onto the filler in the dam forming portion; and (ii) extracting, from the filler, the adsorbed material, wherein the micro device is rotated with respect to a central axis during one of steps (i) and (ii), and the rotation of the micro device is performed at an angular velocity defined by equation 1.

Processes are described herein for the extraction of cannabinoids from cannabis using lipids as an extraction solvent.

A method for modifying the composition of essential oils to be used as such or as ingredients for flavour and fragrance formulations, the process using carbon dioxide and suitable solvents in combination with specific supports; Flavours and fragrances containing ingredients produced by the method and applications using the flavours and fragrances.

The present disclosure relates to non-acidic extracts or fractions selected from a Boswellia low polar gum resin extract fraction (BLPRE), a Boswellia volatile oil fraction (BVOIL), and a Boswellia oil fraction (BOIL) and their compositions. BLPRE, BOIL, and BVOIL are each derived from the gum resin of a Boswellia species. These compositions are useful for improving mental condition, enhancing brain functions such as cognition, memory, learning, communication and brain health, for treating impaired memory, and for preventing, control or treating memory and cognition related disorders/diseases. Additionally, BOIL, BVOIL, and mixtures of BOIL and BVOIL are useful for enhancing the bioavailability of a biological agent.

Embodiments described herein relate generally to plant extract compositions and methods to isolate cutin-derived monomers, oligomers, and mixtures thereof for application in agricultural coating formulations, and in particular, to methods of preparing plant extract compositions that include functionalized and non-functionalized fatty acids and fatty esters (as well as their oligomers and mixtures thereof), which are substantially free from accompanying plant-derived compounds (e.g., proteins, polysaccharides, phenols, lignans, aromatic acids, terpenoids, flavonoids, carotenoids, alkaloids, alcohols, alkanes, and aldehydes) and can be used in agricultural coating formulations.

A useful substance is extracted from botanical feedstock by mechanically compressing the feedstock and pumping a solvent through the compressed feedstock at high pressure while applying compressive mechanical force against the feedstock. Movement of pressurized solvent through the compressed feedstock may increase the volume of solvent in contact with the feedstock. Flow of solvent under pressure may also present a shearing force that facilitates dissociation of the useful substance from the feedstock.

A screen for an extractor system can have a top surface that a solid material contacts during operation of the extractor, a bottom surface opposite the top surface, and a plurality of apertures extending from the top surface through the bottom surface. In one example, the bottom surface of the screen is coated with a non-stick coating while the top surface of the screen is devoid of the non-stick coating.
