The disclosure provides methods and compositions for providing shatter formulations taking the form of crystalline polymorphs, where methods of preparation include preparing tetrahydrocannabinol acid (THCA) powder followed by decarboxylating THCA and removal of terpenes.

A method of extracting one or more chemical extracts from a plant product includes mixing at least a first phytochemical-bearing part of a phytochemical plant product with an oil-bearing plant product, producing an oil mixture from the first phytochemical-bearing part and the oil-bearing plant product using a press device, and extracting at least a chemical extract from the oil mixture.

The present invention relates to a method for the chlorination of a sucrose-6-acylate to produce a 4,1′,6′-trichloro-4,1′,6′-trideoxy-galactosucrose-6-acylate wherein said method includes steps of: (i) combining the sucrose-6-acylate with a chlorinating agent in a reaction vehicle comprising a tertiary amide to afford a mixture; (ii) heating said mixture for a heating period in order to provide chlorination of sucrose-6-acylate at the 4, 1′ and 6′ positions thereof; and (iii) quenching the product stream of (ii) to produce a 4,1′,6′-trichloro-4,1′,6′-trideoxy-galactosucrose-6-acylate;
wherein before said quenching, a portion of said tertiary amide is removed by extraction into a solvent in which said tertiary amide is at least partially soluble.

Centrifugal contactors that can be used for mixing or separating materials are described. The contactors include a sensing system including a communications fiber within the shaft of the contactors and access ports providing access from the communications fiber to the mixing/separating zone of the contactor. The sensing system can be utilized during operation of the contactor and can provide for detailed and accurate on-line characterization of a protocol, as well as process control and system modification as necessary during operation.

The present invention provides an annular centrifugal contactor, having a housing to receive a plurality of liquids; a rotor inside the housing; an annular mixing zone, with a plurality of fluid retention reservoirs; and an adjustable stem that can be raised to restrict the flow of a liquid into the rotor or lowered to increase the flow of liquid into the rotor. The invention also provides a method for transferring moieties from a first liquid to a second liquid, the method having the steps of combining the fluids in a housing whose interior has helically shaped first channels; subjecting the fluids to a spinning rotor to produce a mixture, whereby the channels simultaneously conduct the mixture downwardly and upwardly; and passing the mixture through the rotor to contact second channels, whereby the channels pump the second liquid through a first aperture while the first fluid exits a second aperture.

The problem addressed by the present invention is providing a fluid processing method including extraction that can extract material to be extracted continuously with high efficiency. In a thin film fluid formed between at least two processing surfaces (1, 2) disposed facing each other so as to be able to approach to and separate from each other such that at least one rotates relative to the other, a fluid processing that extracts at least one kind of material to be extracted in at least one kind of the extraction solvent that can extract that material to be extracted is carried out. In addition, the fluid containing at least one kind of material to be extracted and a fluid for extraction that contains the at least one kind of extraction solvent are mixed in the thin film fluid formed between the at least two processing surfaces (1, 2) disposed facing each other so as to be able to approach to and separate from each other such that at least one rotates relative to the other, and a fluid processing process that extracts the at least one kind of material to be extracted into the at least one kind of extraction solvent is carried out.

A method for preparing a Hovenia dulcis Thunb extract rich in dihydromyricetin includes the following steps: (1) crushing Hovenia dulcis Thunb seeds to obtain a Hovenia dulcis Thunb powder; (2) adding a 10-95% ethanol solution in an amount of 3-15 times of an amount of the Hovenia dulcis Thunb powder, stirring and extracting at 20° C-80° C. twice; (3) filtering to obtain an extract solution; (4) concentrating the extract solution by evaporating ethanol under reduced pressure to obtain a crude extract, the crude extract having a solid content of 10%-40%; (5) placing the crude extract at −20° C. to 8° C. for 0.5 to 12 hours; (6) centrifuging the crude extract to obtain a supernatant; and (7) spray-drying the supernatant to obtain the Hovenia dulcis Thunb extract.

A method of extracting one or more chemical extracts from a plant product includes mixing at least a first phytochemical-bearing part of a phytochemical plant product with an oil-bearing plant product, producing an oil mixture from the first phytochemical-bearing part and the oil-bearing plant product using a press device, and extracting at least a chemical extract from the oil mixture.
