This work identifies the chemical components of Azadirachta indica (neem plant) leave extracts . A. indica is a vascular plant which belongs to the Meliaceae family and its use as herb in folk medicine is widely acclaimed. Essential oils were extracted from leaves of A. indica. Steam and solvent extraction methods were used with two sol- vents: Ethanol and Hexane. The crude oil extracted using both extraction methods were analyzed using GC–MS. The result of the analyses show that the major con- stituents were Eicosane (9.7662%), Diacenaphtho[1,2-j:1 � ,2 � -l]fluoranthene (11.301%), Phenol, 4-[[(4-methoxyphenyl)methylene]amino]- (11.84%) and (3Ar,6S,9ar)-1,2,3,4,5,6,7,9a- octahydro-8-methyl-3a,6-methano-3ah-cyclopentacycloocten-10-one (36.883%) in steam extracted oil; Eicosane (10.259%), Diacenaphtho[1,2-j:1 � ,2 � -l]fluoranthene (13.51%) and Butanamide, N-(2-methoxyphenyl)-3-oxo- (16.615%) in the ethanol extracted oil, and (3Ar,6S,9ar)-1,2,3,4,5,6,7,9a-octahydro-8-methyl-3a,6-methano-3ah-cyclopentacycloocten- 10-one (10.72%), n-Hexadecanoic acid (14.688%) and 9,12,15-Octadecatrienoic acid, (Z,Z,Z)- (34.719%) in the hexane extracted A. indica essential oil.
