Abstract: A new saponin, named as Congmuyanoside I {3-O-[β-D-glucopyranosyl (1→3)-β-D-glucopyranosyl] caulophyllogenin}, together with three known compounds, Congmuyanoside A, Congmuyenoside B and 3-O-[β-D-glucopyranosyl (1→2)-β-D-glucopyranosyl] hederagenin were isolated in continuing studies on the buds of Aralia elata (Miq.) Seem. The structure of the new saponin was assigned by NMR spectral data using various 2D techniques.

Key words: structure identification, Aralia elata, triterpenoidal saponin, Congmuyanoside I
