Further monitoring of the fraction with antihepatotoxic activity led to the isolation of an hepatoprotective saikosaponin identified as buddlejasaponin IV and the new malonylbuddlejasaponin IV, determined as saikogenin F-3-O-[6-O-malonyl-β-D-glucopyranosyl-(1→2)-β-D-glucopyranosyl(1→3)]-β-D-fucopyranoside. The structures were elucidated on the basis of the chemical and spectroscopic data.
