인삼(人蔘) 및 유연(類緣) 생약류(生藥類)의 유리(遊離) 및 결합(結合) 지방질(脂肪質)의 지방산(脂肪酸) 결성(結成)

An attempt was made to investigate free and bound lipid contents and fatty acid compositions of ginseng and its eveven kinds related crude drugs. Contents of free and bound lipids of ginseng were 1.23% and 0.47%, and those of the related crude drugs were $0.31{\sim}13.05%$ and $0.26respectively. Fourteen even-numbered and 4 odd-numbered fatty acids were identified by GLC in those lipids from ginseng, and the major fatty acids were linoleic, palmitic, oleic and linolenic acids. The crude drugs are notably different from ginseng in kinds and compositions of fatty acids of free and bound lipids. Composition ratios of unsaturated fatty acids were higher in free lipids from ginseng than those of the crude drugs except 'Won-ji' Polygalae Radix.
