In the present study,
we investigated saponins from this plant except the cyclic-
bisdesmoside-type saponins, seven compounds (Fig. 1) were
isolated including three new triterpene saponins 1–3 and the
structures were elucidated. Furthermore, the cytotoxic activities
toward HCT-116, HT-29, MCF-7 and A549 cell lines in vitro were
evaluated.
