Abstract
Two new triterpenoid saponins, designated sigmoside C and D, have been isolated from the methanol extract of the stem bark of Erythrina sigm oidea in addition to the known soyasapogenol-B and 3-O-[beta-D-glucopy ranosyl]-sitosterol. The structures of the saponins were determined by chemical and spectroscopic means as 22-O-[beta-D-glucopyranosyl]-soya sapogenol-B and 22-O-[alpha-L-rhamnopyranosyl]-soyasapogenol-B, respec tively.
