Abstract

Three main saponins were isolated from the seeds of Albizzia lucida. Their structures were established by spectral analyses and chemical and enzymatic transformations as 3-O-[beta-D-xylopyranosyl(1 --> 2)-alpha-L-arabinopyranosyl (1 --> 6)][beta-D-glucopyranosyl (1 --> 2)]beta-D-glucopyranosyl echinocystic acid; 3-O-[alpha-L-arabinopyranosyl (1 --> 6)][beta-D-glucopyranosyl (1 --> 2)]-beta-D-glucopyranosyl echinocystic acid and 3-O-[beta-D-xylopyranosyl (1 --> 2)-beta-D-fucopyranosyl (1 --> 6)-2-acetamido-2-deoxy-beta-D-glucopyranosyl echinocystic acid, characterized as its methyl ester.
