Authors: UGOCHI O. NJOKU1 AND MARTINS O. OGUGOFOR1*

ABSTRACT
Lantana camara is one of the medicinal plants of verbenacea family, used extensively in herbal medicine to treat several diseases. The present study was carried out to determine the possible phytochemical components present in ethyl acetate fraction of Lantana camara leaves and evaluate the bioactive compounds using Gas Chromatograph-Mass spectrometry. Gas chromatography-mass spectroscopy was used to carry out analysis. Mass spectra of the unknown compounds found in the fraction were matched with standard mass spectra of known components stored in National Institute of Standards and Technology (NIST) library. Result: GC MS analysis produced 19 peaks, corresponding to constituent compounds present in the sample. The eight major phytoconstituents identified were 2,2,4-trimethyl-3-(3,8,12,16-tetramethylheptadeca- 3,7,11,15-tetraenyl)-cyclohexanol, 9,12,15 octadecatrienoic acid, 2, 3- dihydroxypropyl ester, phytol, aromadendrene oxide(-2) and its isomer, spathulenol, 3,7,11,15- tetramethyl-2-hexadecen-1-ol, 6- epi-shyobunol, hexadecanoic acid, and 1-(hydroxymethyl)-1,2- ethanediyl ester. These major compounds add up to 80.15 % of total constituents. Minor constituents identified were caryophyllene, ledene oxide-(II), cycloheptasiloxane tetradecamethyl, propanoic acid,2-[3-acetoxy-4,4,14-trimethylandrost-8-en-17yl], 1,6,10- dodecatrien-3-ol,3,7,11-trimethyl-[s-(z)], humulene, 13-heptadecyn-1-ol, ?- acorenol, ergosta-5,22-dien-3-ol, acetate, [3?, 22E] and 1-heptatriacotanol, all summing up to 19.84 % of total constituents. The presence of various bioactive compounds identified in ethyl acetate fraction of Lantana camara leaves, justifies the use of the plant for diverse ailments by traditional practitioners and can be proposed as a plant of phyto-pharmaceutical relevance. Keywords: Bioactive compounds, GC MS, Lantana camara, medicinal properties
