Abstract:
The extraction and purification of cephalin from the soybean phosphatide were studied in this paper. After washed by acetone to remove greases and free fatty-acids, the soybean phosphatide was treated by ethanol to remove lecithin and then extracted by petroleum ether. For extraction of cephalin with high purity，the best technological parameters were determined as follows: the ratio of solid to liquid ratio of 1:4 (W/V), extract times of 3, and extract temperature of 30 ℃. Under those conditions, the yield of cephalin was 91.9% with the purity of 93.5%.
