A new clnnamylphenol, machaistol(1), along with a known pterocarpan, (+)-medicarpin(2), were isolated as cytotoxic constituents from the stems of Machaerium aristulatum. In addition, a known pterocarpan, (+)-maackiain(3), and a known isoflavone, formononetin(4), were identified as inactive constituents. Compound 1 was eveluated in the in vivo hollow fiber assay with KB, Col-2, and hTERT-RPE1 cells and found to be inactive at the highest does(25 mg/kg body weight) tested.
