Abstract: In this study,content of the lecithin was determined with HPLC,and L9(34) orthogonal design was employed to optimize the extraction technology of lecithin from egg yolk. The results showed that the optimum parameters are as follows:extraction time 2.0 h,alcohol concentration 100% and ratio of solid to liquid 1:7,and under these conditions the purity of lecithin reaches 72.12%.

Key words: lecithin, HPLC, extraction technology
