Abstract:
The total fatty acid in adipose tissue and total and free fatty acid in plasma, using tridecanoic (Cl3:0) and heptadecanoic acid (Cl7:0) as the internal standard (IS) respectively, were analysed by GC. In analysing total fatty acid, the esterification rate was 103.53% (IS Cl3:0) and 102.86% (IS C17:0); the recovery of lauric, myristic, stearic and arachidic acid was 101.0-103,3%, 102,1-494.1%, 103,1-104.5% and 100,0-105.0%; the CV of individual fatty acid were within the range of 2.24-8.46%. In analysing free fatty acid, the esterification rate in use of C17: 0 as the IS was 102.99%; the recovery of lauric, myristic, stearic and arachidic acid was 83.5-87.3%, 96.4-99.6%, 94.3-101.9%, and 82.0-105.0% respectively, the CV of individual fatty acid were within the range of 1.41-6.21%. The procedure analysing total fatty acid is especially simple, speedy, and reliable.
