Three main saponins named albiziasaponins A, B, and C were isolated fr
om the barks of Albizia lebbeck. Their structures were established thr
ough spectral analyses as acacic acid lactone 3-O-beta-D-xylopyranosyl
-(1 --> 2)-alpha-L-arabinopyranosyl-(1 --> 6)-beta-D-glucopyranoside,
3-O-beta-D-glucopyranosyl-(1 --> 2)-O-[alpha-L-arabinopyranosyl-(1 -->
6)]-beta-D-glucopyranoside and 3-O-beta-D-xylopyranosyl-(1 --> 2)-alp
ha-L-arabinopyranosyl-(1 --> 6)-O-[beta-D-glucopyranosyl-(1 --> 2)]-be
ta-D-glucopyranoside.
