摘要：

From the dichloromethane extract of leaves of Macaranga pleiostemona, four antibacterial prenylated flavanones were isolated. Their structures were elucidated by analysis of their spectral data. One, macarangaflavanone A, is a new compound, the remaining three are previously reported natural products. Macarangaflavanone B is clearly shown not to be euchrestaflavanone A. Euchrestaflavanone A and lespedezaflavanone B are revealed to be identical natural products.
