This invention relates to the extraction of psychoactive compounds from organisms for use in medicine. Extraction is carried out with a strong acid or strong base to either promote or inhibit dephosphorylation. The extract in the slurry form is standardized with added excipient so that when it is dried the powdered composition has a specified total psychoactive alkaloid concentration, with a known ratio of phosphorylated to dephosphorylated psychoactive alkaloids.

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.

Botanical materials are treated by processes utilizing a solvent system that includes the use of acetone solvent with or without a CO.sub.2 co-solvent wherein the solvent system is allowed to process the botanical material under certain conditions to obtain extracts (including Whole Plant Extracts) of the botanical materials that are substantially free of pigments, waxes, fats, lipids, and the like.

The system and method of the present invention provides an automated washing and extraction system and method to removed trichomes from cannabis product to create hash resin. Inconsistency is removed from the hash extraction process by automating the washing and extraction cycles thereof. The system and method records the data and tracks all user functions. Manual labor is removed or significantly reduced and time to create the final product is greatly lessened. Thus, more hash can be produced in a shorter amount of time. Moreover, the present invention allows the end user a controlled and accurate and efficient way of producing large quantities of solvent-free hash in a short amount of time while doing so in a consistent, repeatable and cost-effective manner.

The invention provides a method for extraction of at least one extract compound from a material, comprising: a. contacting carbon dioxide with the material to dissolve an amount of the at least one extract compound from the material into the carbon dioxide; b. contacting the carbon dioxide comprising the at least dissolved extract compound with a sorbent to sorb the at least one extract compound onto the sorbent and for regenerating the carbon dioxide; c. recirculating the regenerated carbon dioxide; and d. repeating said recirculating at a constant density of said carbon dioxide of between 100 and 1000 kg/m.sup.3, and repeating said recirculating for at least 10 cycles.

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.

A system, machines and methods for extracting select moieties, flavonoids, and essential oils from plant material without co-extracting chlorophyll, lipids and other undesirable constituents from plants. Super-cooled extraction techniques are taught. Likewise, according to embodiments methods provides 100% grain ethyl alcohol extract with a concentration of chlorophyll that is below 1%.

An extraction device that can include a first solvent chamber, an extraction chamber, a collection chamber and a second solvent chamber. The various chambers of the extraction device are connected in fluid communication with one or more chambers of the device through one or more connectors. A connector can include one or more flow control elements that control flow of fluid from one chamber to one or more other connected chambers. Additionally, the various chambers of the extraction device can be arranged in multiple configurations and connections between the chambers.

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.
