Abstract

Aiming to know the fatty acid composition of areca nut seed oil,the oil extraction from areca nut seeds was carried out with ethyl acetate as solvent.The optimum extraction parameters were ratio of material/solvent 1∶8,temperature 60℃ and time 2h.After methyl-esterification,11 compounds and their relative contents were identified by GC-MS.Results:The main fatty acids of areca nut seed oil are linoleic acid 32.12%,oleic acid 29.50%,and palmitic acid 27.70%.It is indicated that areca nut seed oil has both high level of saturated fatty acid,palmitic acid,and high level of multi-unsaturated fatty acid,linoleic acid.
