Studies on chemical constituents of Asparagus cochinchinensis / 第二军医大学学报

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, Silgel, Sephadex LH-20, ODS, etc. and the structures of the components were identified by physiochemical and spectral analysis, such as MS, 1HNMR, and 13 CNMR. Results: The following 5 components were isolated and identified diosgenin-3-O-p-β-glu- copyranoside(I), smilagenin(II), 26-O-β-D-glucopyranosyl-furost-3β, 22, 26-triol-3-0-p-D-glucopyranosyl(1→2)-O-β-D-glu- copyranoside(JU) 26-0-β-D-glucopyranosyl-furost-5, 20-en-3β, 2α, 26-triol-3-O-[α-α-rhamnopyranosyl (1[2)]-[α-α-rhamnopyranosyl-(1→4)]-β-D- glucopyranoside(IV), and 26-O-β-D-glucopyranosyl-furost-3β, 26-diol-22-methoxy-3-0-α-L-rhamnopyranosy (1-4)-O-β-D-glucopyranoside (V). Conclusion: All the 5 compounds isolated from Asparagus cochinchinensis in this study is reported for the first time.
