Composition and structure of "group B saponin" in soybean seed.

M Shiraiwa1, K Harada, K Okubo.   

Abstract

The composition of "group B saponin" in soybean seed was analyzed by HPLC, and six kinds of "group B saponin," named Ba, Bb, Bb', Bc, Bd and Be according to elution order from HPLC, were detected. Of these saponins, Ba, Bb, Bb' and Bc were identified with soyasaponin V, I, III and II, respectively. Bd and Be were novel saponins possessing soyasapogenol E as the aglycone and the same sugar chain as Ba and Bb, respectively. These saponins were very unstable in the isolated state and had a tendency to form Ba and Bb, respectively. From these results, Bd and Be are presumed to be the precursors of Ba and Bb in soybean seed.
