| Abstract: | Seven phenolic compounds were isolated from the ethanol extract of the pods of Leucanea leucocephala. On the basis of spectral data, they were identified 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 Escherich. coli and Salmonella typhimurium strains. |
