Abstract


This study was conducted to investigate the antioxidant activities on hydropoic-cultured ginseng roots (HGR) and leaves (HGL). The samples were lyophilized, extracted with 80% ethanol, and then evaluated the antioxidant activities compare with conventional-cultured ginseng. Total polyphenol content of ginseng, HGR, and HGL were 128.85±0.41, 115.74±1.28, and 282.15±5.15 mg/g, respectively. The DPPH radical scavenging activity(IC50) was the highest value of 6.47±0.13 mg/mL in the HGL. The ABTS radical scavenging activity was the highest value of 29.37±0.37 mg AA eq/g in HGL, and ginseng and HGR were 10.23±0.49 and 8.18±0.37 mg AA eq/g, respectively. The reducing power of ginseng, HGR, and HGL were 0.56±0.01, 0.53±0.01, and 0.68±0.01, respectively. Chelating effect was the highest value of 92.65±3.42% in HGL. The results of this study suggest that antioxidant activities in hydropoic-cultured ginseng leaves could have significant health benefits. Key words: hydropoic-cultured ginseng, root and leaves, antioxidant activity, polyphenol content, reducing power
