Two triterpenoid saponins were isolated from the methanol extract of Caltha minor leave(Ranunculaceae). The structure of these saponin were elucidated as hederagenin-3-O-$alpha$-rhamnopyranosyl(1$ ightarrow$2)-$alpha$-L-arabinopyrano side and 3-O-$alpha$-L-rhamnopyranosyl(1$ ightarrow$2)-$alpha$-L-arabinopyranosyl hederagenin 28-O-$alpha$-L-rhamnopyranosyl(1$ ightarrow$4)-$eta$-D-glucopyranosyl(1$ ightarrow$6)-$eta$-D-glucopyranosyl ester.
