Abstract
Soyasaponin III has been characterized and the structure of a new triterpenoid saponin, hispidacin, has been elucidated as soyasapogenol B-3-O-alpha-L-rhamnopyranopyranosyl(1----2)- beta-D-glucopyranosyl(1----2)-beta-D-glucuronopyranoside by a combination of fast-atom bombardment mass spectrometry, 13C NMR spectroscopy, and some chemical transformations. Mechanism of transformation of soyasapogenol B to soyasapogenols D, and F has also been rationalized.Entities:
