Abstract

Shimadzu 2010 gas chromatograph equipped with DB-WAX capillary column,37 fatty acid standards and the equivalent chain length(ECL) method were used to identify the fatty acid composition and Δ5-unsaturated fatty acids in Pinus armandii kernel.The results indicated that Pinus armandii kernel abundantly contained unsaturated fatty acid(92.83%),mainly linoleic acid(46.12%) and oleic acid(22.68%).Moreover,large amounts of Δ5-unsaturated fatty acids were also contained,mainly pinolenic acid(16.11%).The ECL method was found to enable effective identification of Δ5-unsaturated fatty acids in Pinus armandii kernel.
