From immature seed of Phaseolus vulgaris L., a novel phytosteryl glucoside was isolated. Strong ion peaks at m/z 613 $[M+Na}^{+},;696;[M+Matrix]^{+}$ in positive F AB- MS and at m/z 589 $[M-1]^{-}$ in negative F AB- MS indicated the molecular weight of the compound is 590. Four hundred MHz $^IH-NMR$ analysis revealed that the compound canys a 24-hydroxy-24-vinyl-cholesterol (saringosterol) as an aglycone and a ${eta}-D-glucopyranose$. Four hundred MHz $^IH-NMR$ analysis of the acetate derivate of the compound revealed that hydroxyls at C-1' in glucose moeity and at C-3 in aglycone have been condensed. Therefore, the phytosteryl glucoside was characterized to be $3-0-{eta}-D-glucopyranosyl-24-hydroxy-24-vinyl-cholesterol$ (saringosteryl glucoside). This is the first demonstration for the presence of saringosterol in higher plants. Also this is the first identification of saringosteryl glucoside in natural materials.erials.
