Abstract

A novel acetylated triterpene bisdesmoside saponin is elucidated as named Hederagenin 3-O-α-L-rhamnopyranosyl ( 3 1 )-[2,4-O-diacetyl-α-L-arabinopyranosyl]-28-O-β-D-glucopyranosyl-( 2 1 ) [3-O-acetyl-β-D-glucopyranosyl] ester (1) along with two known saponins, hederagenin 3-O-(α-L-arabinopyranoside-( 1 3 )-α-L-rhamnopyranosyl-(1→2)-α-L-arabinopyranoside (2) and hederagenin 3-O-[β-D-xylopyranosyl-( 1 3 )-α-L-rhamnopyranosyl-( 1 2 )-α-L-arabinopyranoside] (3), from the pericarps of Sapindus mukorossi. The structures of these saponins were characterized by means of chemical and spectral methods including advanced 2D NMR studies.
