  Furostanol saponins from the fruits ofTribulus terrestris

  摘要：

  Two new steroidal saponins were isolated from the fruits of Tribulus terrestris. Their structures were assigned by spectroscopic analysis and colour reaction as 26-O--D-glucopyranosyl-(25R)-5-furostane-12-one-3,22,26-triol-3-O--D-glucopyranosyl(14)--D-galactopyranoside (1); 26-O--D-glucopyranosyl-25(R)-5-furostan-12-one-3,22,26-triol-3-O--L-rhamnopyranosyl-(12)-O-[-D-glucopyranosyl-(14)]--D-galactopyranoside (2).
