Isolation and identification of chemical constituents from stems of Smilax glabra Roxb.
Objective To study the chemical constituents of the stems of Smilax glabra Roxb. Methods Com-pounds were isolated by the silica gel,macroporous resin,polyamide,ODS and Sephadex LH-20 columns, and their structures were identified on the basis of the physicochemical characters and the spectral analysis. Results Nine compounds were obtained and identified as β-sitosterol palmitate(1),β-sitosterol(2), dau-costerol (3), 1-O-hexadecanoyl-3-O-β-D-galactopyranosyl-glycerol (4), astilbin (5), quercetin (6), taxifolin (7), quercetin-4'-O-β-D-pyranglucoside (8), isoastilbin (9). Conclusions Compounds 1 and 4 are obtained from Smilax L. for the first time, Compound 8 is isolated from this plant for the first time.
