The existing method for the isolation of cephalin from the animal material is not readily applicable to the isolation of the same substance from the plant material. For the isolation of cephalin from the plant material, we have divised a new method involves the precipitation of cephaline by basic lead acetate. The new method is free from such an undesirable result as we had in the existing method. Experimeut I. Egg-yolk cephalin was isolated from egg-yolk oil by precipitating it with CdCl2. Experiment II. Soybean cephalin was isolated from the “Soybean lecithin” (obtained by extraction with benzine) by precipitating it with CdCl2 with basic lead acetate. Experiment III. Soybean cephaline was isolated from the “Soybean lecithin” (obtained by extraction with the mixture of benzine and alcohol) by precipitating it with CdCl2 and with basic lead acetate. Experiment IV. Soybean lecithin and, cephalin were isolated from the “Soybean lecithin” (obtained by extraction with benzine) by precipitating it with basic lead acetate. From these results we can conclude that the precipitation method by means of basic lead acetate is applicable for the separation of cephalin and lecithin and for the isolation of cephalin from the plant material.
