A new bisnortriterpene quinone methide, 20-epi-isoiguesterinol (2), and a new 6-oxophenolic triterpene, 6-oxoisoiguesterin (5), as well as two known compounds, isoiguesterin (1) and isoiguesterinol (4), were isolated from the petroleum ether extract of the roots of Salacia madagascariensis. Isoiguesterin (1) and 20-epi-isoiguesterinol (2) showed potent activity against Leishmania.
