In order to understand the chemical constituents of Leucanea leucocephala, seven phenolic compounds were isolated from the ethanol extract of L. leucocephala pods. On the basis of spectral data, they were identiifed as ethyl protocatechuate (1), syringic acid (2), 3-hydroxy-1-(4-hydroxy-3-methoxyphenyl)propan-1-one (3), caffeic acid methyl ester (4), (Z)-p-coumaric aldehyde (5), 3-methoxy-4-hydroxy-phenylpropane-7,8,9-trio1 (6), and guaiacylglycerol-8-O-4′-(sinapyl alcohol) ether (7). All the compounds were obtained from L. leucocephala for the first time. Compound 1 showed in vitro antibacterial activity against Escherichia coli and Salmonella typhimurium strains.
