Biological compounds such as crude saponin and total polyphenol were determined in Allium hookeri roots and leaves. In addition, activities of DPPH radical scavenging activity, hydroxyl radical scavenging activity, ${\alpha}$-amylase inhibition activity and nitrite scavenging were detected in concentrates of 70% ethanol extracts of Allium hookeri roots and leaves. The crude saponin content of the roots and leaves were 4.28 mg/g, and 4.17 mg/g, respectively. Total polyphenol and total flavonoid content was higher in leaves than roots. Furthermore the DPPH radical scavenging activity and hydroxyl radical scavenging activities of leaves was higher than roots. For ${\alpha}$-glucosidase inhibitory activity, 70% ethanol extracts of Allium hookeri roots and leaves showed 60% activity inhibition at a 10 mg/mL concentration. Nitrite scavenging abilities under acidic conditions were most effective for Allium hookeri leaves extracts. These results suggested that Allium hookeri leaves might be used as the components of health functional food. 삼채뿌리와 잎이 가진 기능성 식품소재로서의 활용도를 높이고자 다양한 생리활성을 평가하였다. 삼채뿌리의 조사포닌, 폴리페놀, 플라보노이드 함량은 각각 4.28 mg/g, 18.27 mg/g, 0.95 mg/g, 삼채잎의 조사포닌, 폴리페놀, 플라보노이드 함량은 각각 4.17mg/g, 35.91 mg/g, 2.79 mg/g으로 나타났다. 삼채뿌리 및 잎 부위의 70% 에탄올 추출물의 DPPH 라디칼 소거능 $IC_{50}$으로 23.01 mg/mL, 4.82 mg/mL로 나타났으며, hydroxyl radical 소거능 $IC_{50}$ 값이 각각 40.82 mg/mL, 27.24 mg/mL를 나타났다. ${\alpha}$-Amylase 저해 활성은 삼채뿌리 및 잎 부위 에탄올 추출물 10 mg/mL를 처리했을 때 억제활성이 각각 61.38%, 61.01%로 나타났다. 삼채뿌리 및 잎 부위의 아질산염 소거능을 측정한 결과, 삼채추출물의 농도가 증가함에 따라 그 활성 역시 증가하는 경향으로 나타났다. 이상의 결과로 삼채뿌리보다는 삼채잎 부위에 항산화 및 항당뇨 활성이 나타났으며, 삼채잎을 활용한 식품 소재로써 개발할 가치가 매우 높은 것으로 판단된다.

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.
