摘要：

Seven steroidal glycosides have been isolated from the fruits of Solanum torvum Swartz. Their structures were established by 2D NMR spectroscopic techniques (H-1,H-1-COSY, TOCSY, NOESY, HSQC, and HMBC) and mass spectrometry as (25S)-26-(beta-D-glucopyranosyloxy)-3-oxo-5 alpha-furost-20 (22)-en-6 alpha-yl-O-beta-D-xylopyranoside (1), (25S)-26-(beta-D-glucopyranosyloxy)-3-oxo-22 alpha-methoxy-5 alpha-furostan-6 alpha-yl-O-beta-D-xylopyranoside (2), (25S)-26-(beta-D-glucopyranosyloxy)-3 beta-hydroxy-22 alpha-methoxy-5 alpha-furostan-6 alpha-yl-O-alpha-L-rhamnopyranosyl-(1 -> 3)-beta-D-glucopyranoside (3), (25S)-3 beta-hydroxy-5 alpha-spirostan-6 alpha-yl-O-beta-D-xylopyranoside (4), (25S)-3-oxo-5 alpha-spirostan-6 alpha-yl-O-beta-D-xylopyranoside (5), (25S)-3 beta-hydroxy-5 alpha-spirostan-6 alpha-yl-O-beta-D-glucopyranoside (6), (25S)-3 beta,27-dihydroxy-5 alpha-spirostan-6 alpha-yl-O-beta-D-glucopyranoside (7).
