Studies on the Lipid Components of Fresh Ginseng, Red Ginseng and White Ginseng

수삼(水蔘), 홍삼(紅蔘) 및 백삼(白蔘)의 지방질성분(脂肪質成分)에 관한 연구(硏究)

Lipid and fatty acid compositions of free lipids and bound lipids from fresh ginseng, red ginseng and white ginseng were studied by means of silicic acid column chromatography, thin-layer chromatography and gas-liquid chromatography. Free lipid and bound lipid contents in those three samples were 1.21 to 1.45% and 0.32 to 0.45%. Neutral lipid fractions in free lipids from the samples were 76.6 to 79.7%, while glycolipid and phospholipid fractions were 11.6 to 14.7% and 8.5 to 8.7%, respectively. The major lipids were triglycerides, sterol esters and hydrocarbons, diglycerides and free sterols in neutral lipids, sterol glucoside, monogalactosyl diglyceride, esterified steryl glycoside, digalactosyl diglyceride in glycolipids and phosphatidyl ethanolamine, phosphatidyl glycerol, phosphatidyl choline and phosphatidyl inositol in phospholipids. Fourteen kinds of even numbered and four kinds of odd numbered fatty acids were identified in the four lipid fractions (TL, NL, GL and PL) by GLC, and the main fatty acids were linoleic acid, palmitic acid, oleic acid and linolenic acid.
