Abstract
The invention relates to a method for producing an extract from cannabis plant matter, containing tetrahydrocannabinol, cannabidiol and optionally the carboxylic acids thereof. According to said method, the dried pint matter is ground and subjected to a CO2 extraction and the primary extract obtained is separated. The invention method permits Δ8 or Δ9 tetrahydrocannabinol to be selectively obtained both from industrial hemp and from drug-producing hemp, optionally after dissolving the primary extract in ethanol, separating undesirable waxes and removing the solvent under reduced pressure.
Claims25
A process for producing an extract containing Tetrahydrocannabinol (THC) and/or cannabidiol (CBD), and optionally the carboxylic acids thereof, from a cannabis plant material or a primary extract thereof, said process comprising:
- (1) subjecting the cannabis plant material or primary extract thereof to CO2 in liquefied form under subcritical pressure and temperature conditions to extract cannabinoid components;
- and
- (2) reducing the pressure and/or temperature to separate tetrahydrocannabinol and/or cannabidiol, and optionally the carboxylic acids thereof, from the CO2.
A process for producing an extract containing Tetrahydrocannabinol (THC) and/or cannabidiol (CBD) from a cannabis plant material or a primary extract thereof, said process comprising:
- (1) decarboxylating cannabinoid carboxylic acids in the cannabis plant material or primary extract thereof;
- (2) subjecting the decarboxylated cannabis plant material or primary extract thereof to CO2 in liquefied form under subcritical pressure and temperature conditions to extract cannabinoid components;
- and
- (3) reducing the pressure and/or temperature to separate tetrahydrocannabinol and/or cannabidiol from the CO2.
