The chemical characteristics of seed oils of Asian ginseng (Panax ginseng C.A. Meyer) at different ages grown in Korea (3, 4 and 5-year old) and China (5-year old), and American ginseng (Panax quinquefoliu L., 5-year old) grown in China were compared. Total fatty acid composition showed a significantly higher oleic acid content in American (87.50%) than in Korean (68.02~69.14%) and Chinese ginseng seed oils (61.19%). At the sn-2 position, the highest oleic acid (81.09%) and lowest linoleic acid (15.77%) were found in American ginseng seed oil. The main triacylglycerol species in ginseng seed oils were triolein (OOO) and 1,2-dioleoyl-3-linoleoyl-glycerol (LOO)/1,3-dioleoyl-2-linoleoyl-glycerol (OLO). In addition, the seed oils possessed an ideal oxidative stability showing 16.55~23.12 hr of induction time by Rancimat test. The results revealed that ginseng seed oil could be developed as a new healthy edible oil, and that the oil's chemical characteristics were strongly associated with the ginseng species and habitats.
