Abstract: Based on relative indissolubility of phospholipid in acetone,phospholipids in egg yolk were extracted in this research. The content of phosphorus was determined with spectrophometry at 630nm. Group X in phospholipid was detected by paper chromatography. At least four fractions of the phospholipids were separated by thin layer chromagraphy and the phenomena was explained.

Key words: lecithin, extract, paper chromatography, thin layer-chromatography
