二十二碳五烯酸

目的：用毛细管气相色谱法测定海狗油中二十碳五烯酸（EPA）、二十二碳五烯酸（DPA）和二十二碳六烯酸（DHA）的含量。

Objective : To determine the contents of eicosapentaenoic acid ( EPA ) , docosapentaenoic acid ( DPA ) and docosahexaenoic acid ( DHA ) in harp seal oil by capillary gas chromatography .

海狗油是从海狗中提取出来的一种油脂，其主要活性成分为多不饱和脂肪酸，如二十碳五烯酸（EPA）、二十二碳五烯酸（DPA）、二十二碳六烯酸（DHA）等。
