Abstract
The fatty acids contents of different solvent extracts of Dennettia tripetala leaves were characterized using GC/MS. Methanol, ethanol and benzene extracted eleven, ten and five fatty acid compounds respectively in varying amounts. The fatty acids extracted by the different solvents identified include: caprylic, capric, lauric, myristic, myristoleic, palmitic, palmitoleic, stearic, oleic, linoleic and linolenic acids. Benzene extracted the highest composition of linolenic acid (omega-3-fatty acid) with percentage composition of 97.76%, while methanol and ethanol extracted highest composition of palmitic acid with percentage compositions of 26.17% and 25.64% respectively. This study revealed that solvent used in extraction has great influence on the type and amount of fatty acids extracted.
