Abstract:
Objective:To study the chemical components in the root of Asparagus cochinchinensis(Lour.)Merr.Methods:Chemical components of Asparagus cochinchinensis root were isolated by column chromatography on macroporous resin,Sil-gel,Sephadex LH-20,ODS,etc.and the structures of the components were identified by physiochemical and spectral analysis,such as MS,1HNMR,and 13CNMR.Results:The following 5 components were isolated and identified:diosgenin-3-O-?-D-glucopyranoside(Ⅰ),smilagenin(Ⅱ),26-O-?-D-glucopyranosyl-furost-3?,22,26-triol-3-O-?-D-glucopyranosyl(1→2)-O-?-D-glucopyranoside(Ⅲ),26-O-?-D-glucopyranosyl-furost-5,20-en-3?,2?,26-triol-3-O-\[?-?-rhamnopyranosyl(1→2)\]-\[?-?-rhamnopyranosyl-(1→4)\]-?-D-glucopyranoside(Ⅳ),and 26-O-?-D-glucopyranosyl-furost-3?,26-diol-22-methoxy-3-O-?-L-rhamnopyranosy(1→4)-O-?-D-glucopyranoside(Ⅴ).Conclusion:All the 5 compounds isolated from Asparagus cochinchinensis in this study is reported for the first time.
