Abstract

Two dammarane-type saponins with a novel aglycon derived from the parent 16,22-epoxy-24-methylidenedammarane and lotoside A, a new lotogenin deriv., were isolated from the MeOH ext. of the stem bark of the Brazilian medicinal plant Zizyphus joazeiro, in addn. to the known saponin 3beta -{[O-[O-[alpha -L-arabinofuranosyl-(1 -> 2)]-O-[beta -D-glucopyranosyl-(1 -> 3)]]-alpha ...
