摘    要:以深海鱼油为基础原料,将其皂化水解为游离脂肪酸,经尿素—甲醇包合粗分离后,以硫酸—甲醇甲酯化,再经硝酸银—硅胶柱层析精分离,得到高纯度的二十碳五烯酸甲酯标准物质。经定值检测,确定其化合物纯度≥98%。

关 键 词:二十碳五烯酸甲酯  鱼油  尿素—甲醇包合  硝酸银—硅胶柱层析

Abstract:Standard substance of eicosapentaenoic acid methyl ester made from a natural source of deep sea fish oil was first saponified in alkaline medium,and separated by enclosing it with urea-methanol,and methylated with sulphuric acid-methanol and separated with silver nitrate-silica gel column by chromatography.The obtained standard substance of eicosapentaenoic acid methyl ester was analyzed qualitatively and quantitatively,and its purity was greater than or equal to 98%.
Keywords:eicosapentaenoic acid methyl ester  fish oil  urea-methanol enclosing  silver nitrate-silica gel column chromatography
