摘要
二亚油酰磷脂酰胆碱是重要的药物辅料,本研究使用冷冻分提的方法提高产品中二亚油酰磷脂酰胆碱的含量。在研究试验条件下,取分提溶剂乙醇的体积分数为95%,液固比为2.5,结晶温度为-7℃,以二亚磷脂酰胆碱含量为49.8%的大豆磷脂酰胆碱为原料,制备得到二亚磷脂酰胆碱含量为59.4%的产品,该产品二亚磷脂酰胆碱含量大于国外同类产品。并通过MS对二亚油酰磷脂酰胆碱进行了进一步确证。
Dilinoleoylphosphatidylcholine is used as important raw material in medicine. The content of dilinoleoylphosphatidylcholine in the product was increased by low temperature enrichment of raw material containing 49.8% dilinoleoylphosphatidylcholine. Under the condition of alcohol content 95% （V/V） ,liquid/solid rate is 2.5 and crystallizing temperature is -7 ℃, the content of dilinoleoylphosphatidylcholine reaches 59.4%.
