摘要: 本文以鸡蛋的卵黄为原料,采用含水乙醇与乙醚提取,通过丙酮脱水去油,得到粗品卵磷脂;进一步以氯仿/甲醇为洗脱液,硅胶柱层析法分离纯化自制的粗品卵磷脂,得到高纯度的纯白色固体卵磷脂,由薄层色谱定性检测,仅含一个斑点;用薄层扫描仪定量检测纯度大于97.4%。

Abstract: With egg yolk as raw material,extracted with aqueous ethanol and ether,and removing water and oil with acetone,a crude phospholipids mixture was obtained.Then the thin-layer chromatography was used with column on silicic acid to purify the phospholipids mixture.Eluated with the solvent mixture(choroform/methanol),ultimately a highly pure white lecithin was obtained.Analysised by thin layer chromatography,there is only one spot.With thin-layer chromatography-scanning method to assay the purity it is higher than 97.4%.

Key words: yolk, phosphatidylcholine, extraction, purification, chromatography on silicic acid
