Minor oxygenated cannabinoids from high potency Cannabis sativa L.

“Nine oxygenated cannabinoids were isolated from a high potency Cannabis sativa L. variety. Structure elucidation was achieved using spectroscopic techniques, including 1D and 2D NMR, HRMS and GC-MS.

These minor compounds include four hexahydrocannabinols, four tetrahydrocannabinols, and one hydroxylated cannabinol, namely 9α-hydroxyhexahydrocannabinol, 7-oxo-9α-hydroxyhexa-hydrocannabinol, 10α-hydroxyhexahydrocannabinol, 10aR-hydroxyhexahydrocannabinol, Δ9-THC aldehyde A, 8-oxo-Δ9-THC, 10aα-hydroxy-10-oxo-Δ8-THC, 9α-hydroxy-10-oxo-Δ6a,10a-THC, and 1’S-hydroxycannabinol, respectively.

The latter compound showed moderate anti-MRSa (IC50 10.0μg/mL), moderate antileishmanial (IC50 14.0μg/mL) and mild antimalarial activity against Plasmodium falciparum (D6 clone) and P. falciparum (W2 clone) with IC50values of 3.4 and 2.3μg/mL, respectively.”

Biologically active cannabinoids from high-potency Cannabis sativa.

Journal of Natural Products

“Nine new cannabinoids (1-9) were isolated from a high-potency variety of Cannabis sativa. Their structures were identified as (+/-)-4-acetoxycannabichromene (1), (+/-)-3”-hydroxy-Delta((4”,5”))-cannabichromene (2), (-)-7-hydroxycannabichromane (3), (-)-7R-cannabicoumarononic acid A (4), 5-acetyl-4-hydroxycannabigerol (5), 4-acetoxy-2-geranyl-5-hydroxy-3-n-pentylphenol (6), 8-hydroxycannabinol (7), 8-hydroxycannabinolic acid A (8), and 2-geranyl-5-hydroxy-3-n-pentyl-1,4-benzoquinone (9) through 1D and 2D NMR spectroscopy, GC-MS, and HRESIMS. The known sterol beta-sitosterol-3-O-beta-d-glucopyranosyl-6′-acetate was isolated for the first time from cannabis. Compounds 6 and 7 displayed significant antibacterial and antifungal activities, respectively, while 5 displayed strong antileishmanial activity.” http://www.ncbi.nlm.nih.gov/pubmed/19344127
