The antibacterial screening of hexane, chloroform and alcohol extracts of leaves of Finlaysonia obovata was carried out against fresh water fish pathogenic bacteria viz., Aeromonas hydrophila, Pseudomonas aeruginosa, Vibrio alginolyticus, Staphylococcus aureus, Escherichia Coli, Edwardsiella tarda and Micrococcus Sp. (multidrug resistant strain) by disc-assay method. The hexane and chloroform extracts were found active against four and five pathogens, respectively. Chromatographic purification of active extracts improved the activity profiles. The GCMS analysis of extracts analysis revealed the presence of triterpenes and hydrocarbons as major constituents. The fatty acids composition of the leaf is also studied by FAME analysis. It contains palmitic acid as a major constituent (54.65%). Two important poly unsaturated fatty acids i.e., Linoleic acid (1.54%) and 9,11-Octadecadienoic acid (3.25%) are also present. © 2007 Asian Network for Scientific Information.
