研究了以3种淡水鱼（鳊、草、链鱼）的内脏鱼油中提取及纯化多烯脂肪酸（PUFA）的工艺，其药用质量标准拟参照鱼脂酸质量标准制定。

Methods for the extraction and purification of poly-unsaturated fatty acid(PUFA)from visceral oil of three fresh-water fish(bream,grass carp and silver carp)were studied. It was suggested that the medicinal quality standard of PUFA could be laid down by referring to the quality standard of Acidummorrhuicum.
