- SYNTHESIS OF PHYTOCANNABINOIDS INCLUDING A DECARBOXYLATION STEP
-
method for decarboxylating a carboxylated phytocannabinoid compound of Formula I to form a phytocannabinoid compound of Formula II: Formula I Formula II wherein: R1 is selected from the group consisting of: substituted or unsubstituted C1-C5 alkyl; R2 is selected from the group consisting of: OH or O, and R3 is selected from the group consisting of: a substituted or unsubstituted cyclohexene, a substituted or unsubstituted C2-C8 alkene, or a substituted or unsubstituted C2-C8 dialkene; or R2 is O, and R2 and R3 together form a ring structure in which R2 is an internal ring atom; wherein the method includes heating a reaction mixture comprising the carboxylated phytocannabinoid compound and a polar aprotic solvent in the presence of a LiCl for a time sufficient to decarboxylate at least a portion of the carboxylated phytocannabinoid compounds and form the phytocannabinoid compound.

- METHOD FOR PURIFYING CANNABINOID COMPOUNDS
-
The present invention relates to methods for purifying one or two cannabinoid compounds using simulated moving bed chromatography, wherein the cannabinoid compound(s) is/are obtained in the extract and/or the raffinate with the total amount of isomeric impurities being below detection level. In particular, the present invention relates to methods for the purification of cannabidiol, trans-(-)-delta-9-tetrahydrocannabinol, cannabidivarin, trans-(-)-delta-9-tetrahydrocannabivarin and cannabigerol which have been obtained by enantiopure synthesis.

- Cannabis. X. The isolation and structures of four new propyl cannabinoid acids, tetrahydrocannabivarinic acid, cannabidivarinic acid, cannabichromevarinic acid and cannabigerovarinic acid, from Thai cannabis, Meao Variant
-
Four new cannabinoids acids, tetrahydrocannabivarinic acid, cannabidivarinic acid, cannabichromevarinic acid and cannabigerovarinic acid were isolated from Thai Cannabis 'Meao variant' and these structures were elucidated on the basis of chemical and spectral data. This is the first example of the isolation of propyl cannabinoid acid from Cannabis.
