建立了一种简便、快速的鸡蛋总脂提取方法，用于鸡蛋中有机氯农药（OCPs）的检测。将蛋黄与无水硫酸钠混合后，用正己烷-乙腈（2：1，v/v）进行提取。没有出现麻烦的乳液。使用本方法，从10 g蛋黄中平均收集3.03 g蛋脂质。与传统方法相比，该方法操作简便，分析时间短，对溶剂的要求低，具有较高的卵脂提取效率和有机氯农药的回收率。(C)1999 Elsevier Science B. V.保留所有权利。
A simple and rapid extraction method of total egg lipids for determination of organochlorine pesticides (OCPs) in the egg was developed. After being mixed with anhydrous sodium sulphate, the extraction of lipids in egg yolk was performed using n-hexane-acetonitrile (2:1, v/v). Troublesome emulsions did not occur. Using the present method, an average of 3.03 g of egg lipids was collected from 10 g of egg yolk. Compared with classical methods, the present method is handy; needs much shorter analysis time and less requirement of solvents and has higher efficiency of egg lipid extraction and higher recoveries of OCPs.
