The lipid compositions of buckwheats produced in Korea were analyzed. The samples used in this experiment were as follows; Kyungbuk rice buckwheat. Kangwon hull buckwheat and Kangwon rice buckwheat. The total lipids were extracted and fractionated to neutral lipids, glycolipids and phospholipids respectively by silicic acid column chromatography (SACC). As a result, neutral lipids content of these three samples were in the range of 82.77-95.65%; glycolipids in 1.97-10.83%; and phospholipids in 2.21-6.40%. The composition of neutral lipids of these three samples showed that triglyceride were in the range of 88.7-92.0%; monoglyceride in 2.3-4.0%; free fatty acid in 3.0-3.7%; diglyceride in 0.7-0.8%.; free sterol in 0-0.7%; and steryl esters in 0-2.2%. The major fatty acids of total lipid, neutral lipid, glycolipids and phospholipids of these three samples were oleic, linoleic and palmitic acids.
