SUPERCRITICAL CO2 EXTRACTION OF TETRAHYDROCANNABINOL AND CANNABIDIOL FROM CANNABIS PLANT MATERIAL

摘要

The invention relates to a method for producing an extract from cannabis plantmatter, containing tetrahydrocannabinol, cannabidiol and optionally thecarboxylic acids thereof. According to said method, the dried plant matter isground and subjected to a CO2 extraction and the primary extract obtained isseparated. The inventive method permits .DELTA.8 or .DELTA.9tetrahydrocannabinol to be selectively obtained both from industrial hemp andfrom drug-producing hemp, optionally after dissolving the primary extract inethanol, separating undesirable waxes and removing the solvent under reducedpressure.
