气相色谱法测定冬瓜子中4种脂肪酸的含量
Determination of content of four kinds of fatty acids in Benincasa hispida seed by GC
摘要
Abstract
Objective:To establish a method for the determination of the content of four kinds fatty acids in benincasa hispida (Thunb.)Cogn.from different origins. Method:The GC was performed on HP-FFAP column (0.22 mm×50 m,0.3μm),nitrogen gas was used as carrier and flow rate was 0.5 mL/min,split ratio was 23∶1,the air flow rate was 450 mL/min,the hydrogen flow rate was 45 mL/min. The column temperature was taken programmed,and the temperature of injector and FID detector was both at 250 ℃. Result:The content of palmtinic acid,octadecanoic acid,oleic acid and linoleic acid in benincasa hispida seed were 2.325%~2.985%,1.198% ~1.771%,2.212%~5.159%,7.383%~13.578%respectively. Conclusion:The method can be used to control the quality of four kinds fatty acids in benincasa hispida seed,which is accurate,convenient and repeatable.关键词
