从大豆磷脂中分离高纯度脑磷脂的研究

研究了用有机溶剂法从大豆磷脂中提取制备高纯度脑磷脂的工艺,大豆磷脂先用丙酮萃洗溶解去除其中的油脂和游离脂肪酸,然后用无水乙醇溶解除去卵磷脂,最后用石油醚萃取沉淀物得高纯度的脑磷脂。对石油醚萃取高纯度脑磷脂的工艺进行了探讨,得到最佳工艺参数为：料液比为1：4（w／V）;萃取次数为3次;萃取温度为30℃。在此工艺条件下脑磷脂的得率为91．9％,纯度为93．5％。

Study on the Extraction Technology of High-purity Cephalin

Studied the craft of producing the high-purity Cephalin from the soybean phosphatide by organic solvent,soybean phosphatide was first washed with acetone to dissolve and remove greases and free fatty-acids,and then used ethanol to dissolve and remove lecithin,finally used petroleum ether to extract sediments and gain high-purity cephalin.Discussed the craft of producing the high-purity Cephalin,and obtained the best technological parameter: The feed liquid ratio was 1:4(W/V);The extract number of times was ...
