Abstract
|
|
|
|
The antioxidant activities of Korean Red Ginseng Extract(RGE) and α-tocopherol, as reference compound, were tested with HPLC and fluorometry which measure the MDA after reacting an aqueous 1% linoleic acid buffer solution, and LDL(1 ㎎ protein/㎖) buffer solution with H₂O₂ and FeCl₂. The generation of conjugated-dime in LDL(0.25 ㎎ protein/㎖) was also measured by spectrometry. MDA determination showed the antioxidant effect on linoleic acid oxidation with oxidation inhibition ratio of 71.8% and 76.1%, respectively, by addition of 1000 ppm RGE and 100 ppm α-tocopherol. LDL(1 ㎎ protein/㎖) oxidation was inhibited by 25.2% and 21.2%, respectively, by addition of 200 ppm REG and 100 ppm α-tocopherol. The generation of conjugated diene in LDL(0.25 ㎎ protein/㎖) was also inhibited by 44.2%, by addition of 50 ppm RGE.
