Abstract

A method based on silca column chromatograph purification and identification by GC-MS has been developed for the isolation of betel nut oil.The crude extract of betel nut oil dissolved in Petroleum ether was separated by TLC and eluted with cyclohexane-acetone(8:2,V/V) as mobile phase.Results showed that the purified betel nut oil comprised 18 types of fatty acids,among which fourteen acid myristic acid accounted for 26.08%,octadecenoic acid(oleic acid) for 24.20%,eighteen carbon acid(linoleic acid) for 22.70%,hexadecanoic acid(palmitic acid) for 14.09%,and dodecanoic acid(lauric acid) 7.87%.Due to diversity of unsaturated fatty acid,betel nut oil has a great potential to develop for health food with function of regulating blood fat and delaying senility.
