title: New saponins from Mangifera indica.
abstract: Two new terpenoidal saponins, indicoside A [1] and indicoside B [2], were isolated from Mangifera indica. Their structures were determined as 28-hydroxylupa-12,20(29)-diene-3-O-[beta-glucopyranosyl-(1-->2)] [-beta-glucopyranosyl-(1-->3)]-alpha-L-arabinopyranoside [1] and 28-hydroxylupa-12,20(29)-diene-3-O-[beta-glucopyranosyl-(1-->3)-al pha-L-rhamnopyranosyl-(1-->2)][beta-glucopyranosyl(1-->3)]-alpha-L- arabinopyranoside [2] on the basis of chemical and spectroscopic studies.
