한방생약자원으로 사용되는 가죽나무(A. altissima)의 뿌리와 줄기, 잎의 열수 추출물을 농도에 따라 전자공여능, SOD유사활성, 아질산염 소거능을 측정하여 항산화 활성에 대하여 분석하였다. 그리고 통풍을 일으키는 원인으로 알려진 xanthine oxidase와 melanin 색소 합성에 작용하는 tyrosinase저해 활성을 측정하여 가죽나무의 생리활성을 분석하였다. 전자공여능은 1.0 mg/mL의 농도에서 뿌리(91.25%) > 줄기(67.03
In this study, extract of Ailanthus altissimawere prepared using hot water under high pressure. The extract were examined for election donating ability (EDA), superoxide dismuase (SOD)-like activity, nitrite scavenging ability (NSA), xanthine oxidase inhibition levels, and tyrosinase inhibition ability. The EDA, using the 1,1-diphenyl-2-picrylhydrazyl method of root extract was 91.25% at 1.0mg/mL. The SOD-like activity of leaf extract was highest at 49.07% and the NSA was 93.33% at pH 1.2, and 85.40% at pH 3.0. The xanthine oxidase inhibitory levels of extracts of A. altissima roots, stems, and leaves were 92.09 97.44% when the extract were tested at 2.0mg/mL. The highest tyrosinase inhibition levels obtained from loot extract were 67.38% at 2.0mg/mL and 63.97% at 0.1mg/mL.
