A new triterpenoid saponin, 3-O-{β-D-xylopyranosyl-(1→2)-b-D-glucopyranosyl-(1→4)-[β-D-glucopyranosyl-(1→2)]-a-L-arabinopyranosyl}-3β,16α,28α-trihydroxy-13β,28-epoxy-oleanan-30-al (ardipusilloside Ⅲ, 1), together with two known saponins,ardisiacrispins A (2) and B (3), were isolated from the whole plants of Ardisia pusilla A. DC. Their structures were elucidated by extensive spectral analysis and chemical evidences. Saponins 1 and 3 exhibited significant cytotoxicity against human glioblastoma U251MG cells.
