From the methanol extract of the fruit pulp of Lagenaria breviflora, three new saponins were characterized as 3-O-β-galactopyranosyl 28-O-β-xylopyranosyl(1-4)-α-rhamnopyranosyl(1-3)-β-xylopyranosyl(1-3)-α-arabinopyranopsylolean-12-en-28-oic acid ester, 3-O-β-galactopyranosyl 28-O-β-galactopyranosyl(1-4)-α-rhamnopyranosyl(1-3)-β-xylopyranosyl(1-3)-α-arabinopyranosylolean-12-en-28-oic acid ester and 3-O-β-galactopyranosyl 28-O-α-arabinopyranosyl(1-6)-β-galactopyranosyl(1-4)-α-rhamnopyranosyl(1-3)-β-xylopyranosyl(1-3)-α-arabinopyranosylolean-12-en-28-oic acid ester.Oleanolic acid and 3-O-acetyloleanolic acid were identified from the hydrolytic products of the pulp.
