Abstract:
OBJECTIVETo study the chemical constituents from the roots and rhizome of Cynanchum atratum.
METHODThe chemical constituents were isolated and repeatedly purified by silica gel chromatography and the structures were elucidated by the NMR spectra and physicochemical properties.
RESULTTwelve compounds were obtained and nine of them were identified as 2, 4-dihyroxyacetophe none (1), 2, 6-dihyroxyacetophenone (2), 4-hydroxybenzenemethanol (3), benzoic acid (4), beta-amyrin acetate (5), palmitic acid (6), beta-sitosterol (7), beta-daucosterol (8), glaucogenin C-3-O-alpha-D-oleandropyranosyl-(1 --> 4)-beta-D-digitoxopyranosyl-(1 -->4)-alpha-D-oleandropyranoside (9).
CONCLUSIONSeven compounds were obtained from C. atratum for the first time.
