From the roots of Caragana sinica (Buc'hoz) Rehder (Leguminosae), a new saponin named caraganoside A was isolated and elucidated as 3-0-$\beta$-D-xylopyranosyl (1$\rightarrow$2)-[$\beta$-D-glucopyranosyl (1$\rightarrow$3)]-$\alpha$-L-arabinopyranosyl oleanolic acid 28-O-[$\beta$-D-glucopyranosyl ester by means of chemical and spectral studies. Kalopanax-saponin F, hemsloside Ma3 and araloside A were also isolated and characterized. The former two compounds were separated as their methylesters.
