| 摘 要： | 建立了一种对油脂中花生四烯酸含量的检测方法,在加入内标的基础上,使用氢氧化钾-甲醇溶液甲酯化,生成的脂肪酸甲酯使用DB-23毛细管柱进行分离检测,结果采用内标法进行分析。结果表明：该方法的回收率在99.58%,仪器精密度RSD为0.45%,方法精密度RSD0.85%,方法重现性RSD0.74%。本方法能准确、有效地对油脂中的花生四烯酸含量进行检测,能满足实际检测工作的需要。

| Abstract: | Based on adding internal label,a method for determination of ARA oil had been established,the sample was methanol etherified by potassium hydroxide mixed with methyl hydrate,and then the methyl ester of aliphatic acid was separated by DB-23 capillary column. The results were:ARA recovery percent was 99. 58%. The relative standard deviation(RSD)of precision of instrument and method was 0. 45% and 0. 85%,respectively. The relative standard deviation(RSD)of repeatability of method was 0. 74%. This method was a... |
