The phytochemical constituents of the leaf and bark of the varieties of Terminalia catappa Linn (red, pink, and white) was analyzed using gas chromatography/mass spectrometry method. A total of 80 constituents were identified in the six methanolic extracts. Cis-oleic acid was identified with highest percentage, 40.85% in the leaf Terminalia cattapa red variety followed by erucic acid, 31.76% in the leaf of T.cattapa pink variety, 25.82% in the leaf of T.cattapa white variety and methyl(16E)-16-octadecanoate, 21.84% in the leaf of T.cattapa white variety. Methyl tridecanoate and methyl heneicosanoate are present in all the six crude extracts. All the six extracts were found to be active against Escherichia coli, Klebsiella pneumonia, Proteus aeruginosa, Streptococcus agalactiae, Staphylococcus aureus, Salmolenella typimurium and Proteus mirabilis at a concentration of 1000, 500 and 250μgml-1 except staphylococcus aureus at 250μgmol-1 in the leaf of T.catappa pink variety. This study, therefore, serves to justify the use of the leaf and bark of this plant in herbal medical practice.
