%X A new triterpenoid saponin, 3-O-¦Â-D-glucopyranosyl-(1¡ú2)-¦Â-D-glucopyranosyl subprogenin D (1), together with six known triterpenoids: subprogenin D (2), abrusgenic acid (3), triptotriterpenic acid B (4), abruslactone A (5), abrusogenin (6) and abrusoside C (7) were isolated from the leaves and stems of Abrus precatorius. Their structures were elucidated on the basis of physical and NMR analysis, respectively. Compounds 5 and 6 showed moderate cytotoxicity against MCF-7, SW1990, Hela, and Du-145 cell lines. Compounds 1, 2 and 4 were isolated from this plant for the first time.
