Triterpene saponins of Trigonella monspeliaca L.

Abstract

The triterpene saponin fraction was isolated from Trigonella monspeliaca tops. It consisted of ten saponosides, three of which were determined to be medicagenic acid glycosides, the other seven - soyasapogenol glucosides. Acid hydrolysis of the saponin fraction yielded medicagenic acid, soyasapogenol B and its artifacts soyasapogenol C, D and F. These data consitute the first report on the occurence of medicagenic acid and soyasapogenol glycosides in the genus Trigonella.
