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.
