Abstract

Physicochemical properties and fatty acid compositions of jujube kernel oil were studied.Six main kinds of fatty acids were found in jujube kernel oil.The higher content of them were oleic acid and linoleic acid,their content were 49.1% and 26.0%,respectively.The distribution of fatty acid of triacylglycerol was confirmed in jujube kernel oil by determining the composition of Sn-2 fatty acid.The content of total tocopherol was 18.67 mg per (100 g) jujube kernel oil.The unsaponifiable matter was analyzed by using capillary gas chromatography mass spectrometer(GC/MS),and 7 compounds were determined,the content of sgualene was 39.2% based on the content of unsaponifiable matter which was the highest component in unsaponifiable matter.
