Abstract

|
|
The antioxidative action of petroleum ether, chloroform, chloroform-methamol (2 : 1, v/v), methanol and methanol-water extracts of Panax ginseng roots in the autoxidation of mixed methyl esters of unsaturated fatty acids (MEUFA) was investigated in vitro.
All of the extracts of Panax ginseng roots possessed antioxidative activity and inhibited the formation of hydroperoxides in the autoxidation of mixed methyl esters of unsaturated fatty acids (MEUEA). The induction period in the autoxidation of MEUFA was extended by the addition of each extract. The antioxidative activity was more prominent with chloroform and chloroform-methanol (2 : 1, v/v) extracts than with other extracts. The antioxidative activity of each extract estimated by Olcott´s oven test and the measurement of peroxide value (POV) showed a similar tendency. From the results obtained, it was conclude that extracts of Panax ginseng roots had remarkable antioxidative activity in the autoxidation of MEUFA in vitro.
