In order to investigate polar lipid ingredients and fat쇼 acid compositions in corn embryo, lipids were extracted with n-hexane (HX), pet. ether (PE), chloroform-methanol (2:1, v/v) (CM), dichoromethane-methanol (2:1, v/v DM) and hexane-diethyl ether (5:1, v/v HD). Of the glycolipid in polar lipids were separated by thin layer chormatogarphy (TLC), monoglycosyl diacyglycerol was most efficient with CM, HD, and monoglycosy sterol and monoglycosyl ceramide were similar to five solvents, but HX, PE and DM, HD were somewhat superior, respectively. Of the phospholipid, phosphatidyl inositol was most efficient with CM, DM, and phosphatidyl choline was similar to five solvents as well. Phosphatidyl serine was superior PE, HD, CM to HX, and phosphatidyl ethanolamine was inferior CM to HX. The major fatty acid in the glycolipid was linoleic acid, and it was most efficient with CM the same as plamitic acid, but oleic acid was superior in using HX, PE. The major fatty acids in the phospholipid were palmitic, heptadecanoic aicds, and they were superior in using HX and PE, respectively. Also oleic acid was most efficient with HX and CM, but HD was somewhat inferior.
