Abstract: Five triterpenoid compounds (Ⅰ~Ⅴ): saikogenin D, saikosaponin g, prosaikogenin H, saikosaponin b2 and saikosaponin p were separated from Bupleurum smithii Wolff var. parvifolium for the first time, the last one being a new saponin. On the basis of the physical, chemical properties and spectral analysis, its structure was identified as 3β, 16β, 23, 28-tetrahydroxyoleana-ll, 13 (18)-diene-3-O-β-D-glucopyranosyl (1→6)-[β-D-glucopy-ranosyl- (1→2) ]-β-D-glucopyranoside.

Key words: Bupleurum smithii var. parvdfolium, Triterpenoid saponin, Saikosaponin p
