Four triterpenoidal saponins, prosaikogenin A and saikosaponins b₁, n and o, were isolated from the roots of the title plant for the first time. Saikosaponin O is a new compound, which was identified as 3β,16β,23,28- tetrahydroxyolean-11,13(18)-diene-3-O-β-D-glucopyranosyl-(1 → 2)-β-D- glucopyranosyl-(1 → 6)-[β-D-glucopyranosyl-(1 → 2)]-β-D-glucopyranoside.
