Abstract

This study was performed to determine the antimutagenic and cytotoxic effect of Aster scaber root ethanol extract on Salmonella typhymurium TA98, TA100 and cancer cell lines using Ames test and cytotoxicity assay, respectively. Cancer cell lines include chronic myelogenous leukemia(K562), human gastric carcinoma(KATOIII), human hepatocellular carcinoma(Hep3B) and human breast adenocarcinoma(MCF-7). Futher fractionations with hexane, chloroform, ethyl acetate, butanol and water from ethanol extract of Aster scaber root were performed to obtain effective fraction. Ethanol extract and ethyl acetate fraction showed 79% and 82% inhibitory effect on the mutagenesis induced by N-methyl-N'-nitro-N-nitrosoguanidine(MNNG) against TA100, while 48% and 60% inhibition was observed on the mutagenesis induced by 4-nitroquinoline-l-oxide(4NQO) against TA98. In the meanwhile, ethyl acetate fraction showed 78% and 85% inhibitory effect on the mutagenesis induced by benzo(${\alpha}$)pyrene[B(${\alpha}$)P] against TA98 and TA100, respectively, while 83% inhibition was observed on the mutagenesis induced by 3-amino-l,4-dimethyl-5H-pyrido(4,3-b) indole(Trp-P-1) against TA98. Ethyl acetate fraction (0.125 mg/ml) showed the strongest cytotoxic effect against K562, KATOIII, Hep3B and MCF-7 at the same concentration compared to those of other fractions. Ethanol extract and water fraction showed the least inhibitory effect.

참취뿌리의 에탄올 추출물과 용매 분획물에 대한 생리활성 효과를 밝히기 위해 항돌연변이성 및 암세포 성장억제효과를 실시한 결과 에탄올 추출물 자체의 돌연변이성은 없었다. 직접변이원인 N-methyl-N'-nitro-N-nitrosoguanidine(MNNG)에 대해서는 Salmonella typhimurium TA100의 경우 에탄올 추출물이 79%, 에틸아세테이트 분획물은 82%의 억제효과를 나타내었다. 4-Nitroquinoline-1-oxide(4NQO)에 대해서는 Salmonella typhimurium TA98에서 에탄올 추출물이 48%, 에틸 아세테이트 분획물은 60%의 억제효과를 보였다. 한편 간접 변이원인 benzo(${\alpha}$)pyrene[B(${\alpha}$)P]에 대해서는 에틸아세테이트 분획물의 경우 TA98에서는 78%, TA100에서는 85%의 높은 억제활성을 나타내었다. 그리고 3-amino-1,4-dimethyl-5H-pyrido(4,3-b)indole(Trp-P-1)에 대해서는 TA98에서 89%의 높은 억제효과를 보였다. 한편 참취 에탄올 추출물에 대한 암세포 성장억제 실험에서도 chronic myelogenous leukemia (K562), human gastric carcinoma (KATOIII), human hepatocellular carcinoma (Hep3B) 및 human breast adenocarcioma (MCF-7)에 대하여 높은 세포독성을 나타내었으며 용매 분획물의 경우 KATOIII 세포에서는 모든 분획물이 높은 세포독성을 나타내었으나 그외세포에 대해서는 물분획물을 제외한 에틸아세테이트, 부탄올 및 클로로포름 분획물이 높은 세포독성을 나타내었다.
