摘要：

Two new furostanol saponins, together with two known steroidal saponins, were isolated from the seeds of Trigonella foenum-graecum L. The structures of the new compounds were determined by detailed analysis of 1D NMR, 2D NMR, MS spectra and chemical evidences as 26-O-beta-D-glucopyranosyl-(25S)-5-en-furost-3 beta, 22 alpha, 26-triol 3-O-alpha-L-rhamnopyranosyl-(1 -> 2)-[beta-D-glucopyranosyl-(1 -> 6)-beta-D-glucopyranosyl-(1 -> 3)-beta-D-glucopyranosyl-(1 -> 4)]-beta-D-glucopyranoside (1) and 26-O-beta-D- glucopyranosyl-(25R)-5-en-furost-3 beta, 22 alpha, 26-triol 3-O-alpha-L-rhamnopyranosyl(1 -> 2)-[beta-D-glucopyranosyl-(1 -> 6)]-beta-D-glucopyranosyl-(1 -> 3)-beta-D-glucopyranosyl-(1 -> 4)]-beta-D-glucopyranoside (2).
