Chemical constituents in the extracts of Leucaena leucocephala (Lamk.) de Wit. and Salix babylonica L. foliage were identified by gas chromatography-mass spectrometry and their relative concentrations determined. L. leucocephala extract contained 44 compounds: 2(H)-benzofuranone-5,6,7,7a-tetrahydro-4,4,7a-trimethyl (23.1%), pentadecanoic acid-14-methyl-methyl ester (8.2%), and 6,10,14- trimethyl-2-pentadecanone a ketone (4.2%) were the principal constituents. Fifty nine compounds were identified in S. babylonica leaves, but the main constituents were tritetracontane (15.2%), octadecenoic acid-1,2,3-propanetriyl ester (11.1%), hexadecanoic acid-methyl ester (10.5%), and 1,3-dioxane-4-(hexadecyloxy)-2-pentadecyl (10.3%). Results suggest that the alcohol extract is mainly composed of oxygenated hydrocarbons of C10 to C60 compounds and contains predominantly phenolic hydrocarbons.Downloads
