Abstract
Phytochemical investigation of the fruit of Acronychia pedunculata (L.) Miq. led to the isolation of a new prenylated flavone, acroflavone A (1), together with eight known compounds (2–9). Their structures were elucidated by thorough analysis of mass spectrometric and NMR spectroscopic data. The isolated compounds were evaluated against several bacterial strains. Three known compounds (3–5) demonstrated antibacterial activities. Among them, acrovestone (5) proved equally or more potent than chloramphenicol against three out of the four strains tested.
