Stilbene C-glucosides from Cissus repens.
Four new stilbene C-glucosides, namely trans-3-O-methyl-resveratrol-2-C-beta-glucoside (1), cis-3-O-methyl-resveratrol-2-C-beta-glucoside (2), trans-3-O-methyl-resveratrol-2-(2-p-coumaric)-C-beta-glucoside (cissuside A) (3), and trans-3-O-methyl-resveratrol-2-(3-p-coumaric)-C-beta-glucoside (cissuside B) (4), were isolated from the aerial parts of Cissus repens, along with known trans-resveratrol (5), trans-resveratrol-2-C-beta-glucoside (6) and cis-resveratrol-2-C-beta-glucoside (7). Their structures were established by spectroscopic methods. Stilbene C-glucosides were found in the genus Cissus for the first time.
