Gas chromatography of cannabinoids

Gas chromatography of cannabinoids. Gas chromatographic behaviour of cis- and trans- tetrahydrocannabinol and isotetrahydrocannabinol.

Estimation of Biologically Active Cannabinoids in Cannabis indica by Gas Chromatography-mass Spectrometry (GC-MS)

Cannabis indica was collected from five different localities of Pakistan and analyzed for medicinally active compounds by GC-MS. The biologically active chemical compounds amongst the naturally occurring cannabinoids are delta 9-tetrahydrocannabinol (THC) and cannabidiol (CBD) which were present in all samples in high percentage. The highest percentage of THC present was 23.84% and that of CBD ...

(tetrahydrofuran) at 703C for 16 h. The ester residue is then converted to a 6,6-dideuteriohexose residue, the O-methyl ethers of which are easily distinguishable by GC-MS of the derived alditol acetates. An alternative to acid hydrolysis that is applicable to most polysaccharides and glycoconjugates, including those containing acid-labile residues or glycosidic linkages resistant to hydrolysis...
