The petroleum ether extract of Astragalus complanatus R. Br. showed activity for lowering the transaminase levels in mice. From this extract six compounds were isolated. Among them five were identified as rhamnocitrin (I), formononetin (II), stigmasterol (IV), phosphatidylethanolamine (V) and phosphatidylinositol (VI). The other one was shown to be a new p-coumaroyl derivative, 11-O-p-coumarylnepeticin. Their structures were elucidated by spectrometric and chemical analyses. All the six compounds were isolated from this plant for the first time.
