Phytochemical investigation of Aglaia odorata var. microphyllina led to the isolation of two new rocaglamide derivatives and three known ones. The structures of the two new compounds were elucidated as 8b-methoxy-desmethylrocaglamide (1) and 3′-hydroxy-8b-methoxy-rocaglamide (2) by spectroscopic techniques (IR, MS, 1D and 2D NMR) and comparing with published data. All the five compounds were evaluated for cytotoxic activity against K562 cell line by MTT method. The results indicated that the OH at 8b position was a decisive group for cytotoxic activity.
