Abstract
|
|
|
|
To isolate new antioxidants from Panax ginseng, methanol extract of Panax ginseng was fractionated into several subfractions and their antioxidant activities were measured by using α, α-diphenyl-β-picrylhydrazyl (DPPH). Four compounds were isolated from two subfractions that showed high DPPH quenching activities by silica gel, μ Bondapak C_(18) or Sephadex LH-20 column chromatography. The four compounds were confirmed to be phenolic substances by color reaction and UV spectral analysis.
