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$\rightarrow$2)-$\alpha$-L-arabinopyrano side and 3-O-$\alpha$-L-rhamnopyranosyl(1$\rightarrow$2)-$\alpha$-L-arabinopyranosyl hederagenin 28-O-$\alpha$-L-rhamnopyranosyl(1$\rightarrow$4)-$\beta$-D-glucopyranosyl(1$\rightarrow$6)-$\beta$-D-glucopyranosyl ester.
