Estimation of quail egg yolk plasma phospholipids after fragmentation by thin layer chromatography method.

The purpose of this study was the separation and dosage of quail egg yolk plasma phospholipids. The phospholipids have been fragmentised using the thin layer chromatography method, while their dosage has been made by estimating phosphorus, after the perchloric acid digestion. The obtained results have demonstrated the presence of phosphatidylcholine in large quantity (74.8%), as well as the presence of the other phospholipids: phosphatidylethanolamine (11.3%), phosphatidylserine (4.3%), sphyngomielin (6.5%) and lysophosphatidylcholine (3.1%). Due to the high level of phosphatidylcholine, as well as the presence of sphyngomielin, the use of quail eggs in diets is highly recommended, as these phospholipids contribute to the decrease of lymphatic absorption of cholesterol.
