직접 돌연변이원에 대한 가시오갈피 추출물의 항돌연변이 효과

Inhibitory Effect of Methanol Extract of Eleutherococcus senticosus Maxim. on the Direct Mutagen Mutagenicity

초록

Ames test (S. typhimurium TA98, TA100)에서 6종의 직접변이원에 대한 가시오갈피(뿌리, 줄기, 잎)의 메탄을 추출물 및 용매 분획물의 항돌연변이 효과를 고찰하였다. Salmonella typhimuriun TA98, TA100에서, 6종의 직접변이원으로 유도된 각각의 변이원성에 대한 가시오갈피 뿌리, 줄기 및 잎의 메탄을 추출물의 돌연변이 억제효과를 검색한 결과 1-nitropyrene의 변이원성에 대하여 선택적으로 강한 억제효과를 나타내었다. 따라서 1-nitropyrene 변이원의 돌연변이원성에 대한 용매분획물의 활성을 비교한 결과 클로로포름 분획물이 가장 강한 억제효과를 나타내었다. S. typhimurium TA98, TA100에서, 뿌리의 클로로포름 분획물은 세포내 항돌연변이 효과를 강하게 나타낸 반면 줄기와 잎은 세포내 돌연변이 억제효과를 나타내지 않았다. 이 결과로부터 가시오갈피 뿌리에는 주로 세포내 항돌연변이 효과를, 줄기와 잎에는 세포외 항돌연변이 효과를 강하게 나타내는 활성 성분이 함유되어 있음을 알 수 있었다.

Abstract

Antimutagenic effects og Eleutherococcus senticosus Maxim. on the mutagenicty induced by mutagens, 4-NQO, MNNG, $\textrm{NaN}_{3}$, 2-NF, and 1-NP was studied by the Ames test with Salmonella typhimurium TA98 and TA100. The methanol extract ($500\mu\textrm{g}$/plate) of E. senticosus Maxim. showed inhibitory effect on the mutagenicty induced by 1-NP only among the tested mutagens. In S. typhimurium TA98, the methanol extracts of the root, stem and leaf showed inhibitory effects of 54.9, 29.5, and 32.9% inhibition on 1-NP mutagenicity, respectively. In S typhimurium TA100, the methanol extracts of the root, stem, and leaf showed inhibitory effects of 593, 30.2, and 43.6%, respectively. The methanol extract were further fractionated by a subsequent liquid-liquid partition technique with chloroform, butanol, and water. The chloroform ($300\mu\textrm{g}$/plate) fraction of the root, stem and leaf showed the strong antimutagenic effects on the mutagenicity induced by 1-NP in S typhimurium TA98 and TA100. But none or weak antimutagenicities were observed in the butanol and aqueous fraction. The chloroform fractions of root, stem and leaf showed the antimutagenic effects of 61.6~88.6% in a dose-dependent manner. In the antimutagenic mode test, the inhibition effect of root was mainly bio-antimutagenic, whereas stem and leaf were desmutagenic.
