The disclosure relates to decarboxylated cannabis resins and methods of making the decarboxylated cannabis resins by extraction and decarboxylation of cannabinoids from Cannabis species using microwaves and solvents. The disclosure also relates to use of the decarboxylated cannabis resins for making pharmaceutical products comprising same.

An example method of extracting phytocannabinoids from plants includes obtaining plant parts from at least one plant, the at least one plant including one or more of Cannabis, Turmeric, Ginseng, Ginkgo, Ginger, Vinca, and Bacopa. The plant parts are cooled, and are incubated in an incubation mixture of cellulose, pectinase, amylase, and proteinase dissolved in a buffer. The incubation mixture is evaporated in an evaporation chamber to obtain a phytocannabinoid extract.

A system and method for extracting and separating botanical oils and compounds from botanical material without the use of solvents, having a vaporizing section which is further coupled to a centrifugal electrostatic precipitator for collection and segregation. The vaporizing section receives the botanical material through which a temperature-controlled inert gas is passed to evaporate specific vaporization temperature oils or compounds from the botanical material. The extracted vapor passes to the centrifugal electrostatic precipitator where the oil or compound is reduced back to the liquid state and is collected and segregated. The oils having the lower vapor temperature are collected first and the remaining oils are collected by specific and progressive vaporization temperature control. In some examples, selected vaporized compounds are waste exhausted as vapor by bypassing the centrifugal electrostatic precipitator at specific known vapor temperatures, thereby eliminating potentially toxic or undesirable oils or compounds from being collected.

The disclosure also relates to use of the decarboxylated cannabis resins for making pharmaceutical products comprising same.

The disclosed articles, apparatus, methods, and compositions provide for the integration of different and environmentally-friendly processes for extraction, stabilization, and formulation of active compounds with health and/or other benefits from lignocellulosic by-products of food processes. The active compounds can include one or more of polyphenols, flavonoids, o-diphenols, anthocyanins, and phenolic acids. A high-pressure, high-temperature extraction process provides a means to recover a substantial portion of the active compounds from a biomass feedstock. The corresponding extract can be encapsulated, which provides a convenient form for stabilization and delivery of the active compounds into a final product, for example an active packaging material or corresponding actively packaged food item.

Disclosed is a microwave chemical method for totally extracting fluorine and rare earth from bastnaesite concentrate, including: alkaline conversion defluorination of bastnaesite through microwave irradiation, microwave-assisted leaching of fluorine, solid-liquid separation of leaching solution and microwave-assisted leaching of rare earth. The rare earth hydrochloric acid solution for leaching contains no fluorine ion, so that the fluorine interference of subsequent processes such as impurity removal can be completely avoided; the fluorine and the rare earth are leached with microwaves, which does not need the stirring, so that the automatic control is easy to implement; the fluorine and rare earth leaching speed is high, the leaching time is short and the complete leaching of fluorine and little residual alkali in the slag can be realized by two-time leaching; and no fluorine-containing waste water is discharged, and the total extraction of the rare earth can be realized by one-time leaching.

An automatic extraction device for extracting a liquid substance (e.g., oil) from plant material, is disclosed. The device comprising: an ethanol source, a mixing tank, in liquid connection with the ethanol source, comprising: an entrance for providing the plant material; a mixer, and an exit for extracting a mixture of the ethanol and the liquid substance, an evaporation system, in liquid connection to the mixing tank's exit, for evaporating the ethanol; and a condenser, for condensing the evaporated ethanol, the condenser. In some embodiments, the condenser may include: an entrance in gas connection with the evaporation system; a housing having a maximum external volume of at most 1 liter; and an internal array of heatsinks, located inside the housing, providing a surface-to-volume ratio of 4-0.5 [1/mm]; and a collecting tube, in liquid connection to the mixing tank, for collecting the condensed ethanol.

The disclosure provides embodiments processing and extracting compounds from cannabis. In one embodiment, the method includes providing a composition comprising the cannabis; inserting the composition into a treatment zone; applying a pulsed electric field to the composition within the treatment zone, wherein a portion of the cell membranes of the cannabis are lysed by electroporation to provide a product comprising a lysate; and separating at least a portion of a compound within the lysate from a remainder of the product.

Methods for isolation of ferulic acid and/or p-coumaric acid from lignin paste that may be a resulting waste product from the bioethanol process using sugarcane bagasse or corn stover.
