The 70% ethanol extract of the roots of Millettia speciosa gave two new oleanane-type saponins along with two known pterocarpans, medicarpin and maackiain. The structures of new compounds were established on the basis of chemical and spectroscopic evidences. Medicarpin and maackiain showed cytotoxicity against leukemia cells (HL-60) and inhibited leukotrine secretion from RBL-2H3 cells.
