Objective: To study the chemical constituents of Akebia trifoliata.Method: The compounds were separated and purified by column chromatography and their structures were established by spectroscopic methods. Result: Fifteen compounds were isolated from the extract of A. trifoliata

whose structures were determined as 3-O-β-D-glucopyranosyl(1→3)-α-L-rhamnopyranosyl-(1→2)-α-L-arabinopyranosyl hederagenin(1)

3-O-β-D-xylopyranosyl-(1→2)-α-L-arabinopyranosyl hederagenin(2)
