Abstract:
Objective: To study the steroidal saponins from Allii Macrostemonis Bulbus. Methods The silica gel and ODS column chromatographies were used for the isolation and purification of compounds from Allii Macrostemonis Bulbus. Their structures were identified through comparing with references and spectral analyses. Results: Three steroidal saponins were isolated from the 70% ethanol extract from Allii Macrostemonis Bulbus and identified as 5β-spirostane-25(27)-en-3β, 12β-diol-3-O-β-D-glucopyranosyl- (1→2)-β-D-galactopyranoside (1), (25R)-5β-spirostane-3β, 12β-diol-3-O-β-D-glucopyranosyl- (1→2)-β-D-galactopyranoside (2), and 5β-spirostane-25(27)-en-2β, 3β-diol-3-O-β-D-glucopyranosyl- (1→2)-β-D-galactopyranoside (3). Conclusion: Compound 1 is a new compound named macrostemonoside S. Compound 2 is isolated from Allii Macrostemonis Bulbus for the first time.
