[Studies on the chemical constituents from Cissus assamica].Zhong Yao Cai. 2009 Feb; 32(2):210-3.ZY
To study the chemical constituents from Cissus assamica and obtain a more comprehensive understanding of its effective components.
Compounds were isolated by various column chromatographies with silica gel. Their structures were elucidated by spectral analysis (IR, MS, 1H-NMR, 13C-NMR) and chemical evidence.
Eight compounds were isolated and elucidated as ursolic acid (I), lupeol (II), n-hexacosinc acid (III), isolariciresinol-9-O-beta-D-glucopyranoside (IV), dauco sterin (V), 3,3'-dimethyl ellagic acid (VI), beta-Sitosterol (VII), bergenin (VIII).
Among these compounds, I-V are isolated from this plant for the first time.
