  Steroidal saponins from the fruits of Solanum torvum

  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).
