The lipid and fatty acid compositions of neutral lipid, glycolipid and phospholipid were identified and quantified by thin-layer chromatography and gas chromatography. Main constituents of the neutral lipid were triglyceride, free sterol and esterified sterol in the free lipid, and free fatty acid and monoglyceride in the bound lipid. In the outer part, there existed 25.7% triglyceride in the free lipid and it was not nearly found in the bound lipid. Main constitutents of the glycolipid were digalactosyl diglyceride and esterified steryl glycoside in the free lipid, and digalactosyl diglyceride in the bound lipid. Free lipid didn`t contain trigalactosyl diglyceride but bound lipid contained 2.0% of it. Main constituents of the phospholipid were lysophosphatidyl choline, phosphatidyl inositol, phosphatidyl choline, phosphatidyl glycerol and phosphatidyl ethanolamine in the free lipid, and phosphatidyl choline and phosophatidyl inositol in the bound lipid. The predominant fatty acids of three fractions, neutral lipid, glycolipid and phospholipid showed almost the same pattern as that of the total free and bound lipids. The content of palmitic acid was relatively higher in the polar lipids(glyco and phospholipid). Therefore, saturated fatty acid ratio of polar lipid was higher than that of neutral lipid. found lipid contained more saturated fatty acids as compared with the free lipid.
