Studies on the Causal Component of Rusty-Root on Panax ginseng I. Antioxidative Activity Oriented
적변인삼 유발 물질 구명 I. 항산화 활성을 중심으로
Abstract
To analyze the correlation between the rusty root and the antiokidative activity in ginseng (Panax ginseng C.A.Meyer) roots, the levels of antioxidative activity in various tissues of healthy and rusty roots. The superoxide dismutase activity in rusty roots (126.9 units/mg protein) was approximately 3.5 times higher than that in healthy roots. The catalase activity in rusty roots was approximately 1.6 times higher than that in healthy roots, whereas the peroxidase activity showed a slight low level in msty roots. The 1.1 diphenyl-2-picryl-hydrazyl(DPPH) free radical scavenging activity in rusty roots was approximately 2.0 times higher than that in healthy roots. The total ascorbate content in healthy roots was 166~240
적변인삼의 원인 물질을 구명코저 인삼뿌리의 적변현상과 항산화 활성과의 상관관계를 조사하기 위하여 적변뿌리와 건전뿌리의 각 부위별 항산화 활성을 조사하였다. 적변삼의 표피와 피층조직의 superoxide dismutase(SOD) 활성(units/mg protein)은 각각 126.9와 79.6으로 정상뿌리에 비해 각각 3.5배, 2.0배 높았다. 적변뿌리의 catalase활성은 약 1.6배 높았으나, peroxidase 활성은 오히려 약간 낮았다. 적변뿌리 각 조직의 DPPH 자유라디칼 포착활성은 정상뿌리에 비해 약 2.0배 높았다. 정상뿌리의 ascorbate 함량은 조직에 따라 약간의 차이를 나타내었지만(166~240
