制备

方法一、醇-醚分离

提取胆固醇和卵磷脂 取新鲜或冷冻大脑或脊髓，去膜及血丝等杂质，绞碎，用1.2倍量丙酮浸渍4.5h，不断搅拌，过滤，反复浸渍5次，滤液制胆固醇。滤饼真空干燥，加入2-3倍量乙醇，于35-40℃提取12h，过滤，再提取1次，滤液制卵磷脂，滤饼真空干燥。

沉淀物的制备 滤饼中加入乙醚提取12h，过滤，再提取1次，合并两次滤液，滤液浓缩，得浓缩液。将浓缩液0℃放置12h，离心，取上清液加入60℃乙醇，边加边搅拌，过滤，收集沉淀物。

滤饼[乙醚]→[12h]滤液[浓缩，离心]→上清液[乙醇]→沉淀物

脑磷脂成品的制备 在沉淀中加入乙醚，0℃静置，过滤，得滤液。滤液中加入乙醇，沉淀，过滤，收集沉淀物，真空干燥，即得脑磷脂成品。

沉淀物[乙醚]→[0℃]滤液[乙醇]→脑磷脂成品

方法二、氯化钙沉淀

粗制脑磷脂的制备 取大脑干加3倍量乙醚，加热至沸，过滤，滤渣再提取一次，合并两次滤液，将滤液浓缩至1/3体积，得浓缩液。
