Abstract

This study was performed to determine the antimutagenic and anticancer effects of ethanol extract of buckwheat sprout using Ames test and SRB assay, respectively. An ethyl acetate fraction (200 ${\mu}/plate$) from the ethanol extract of buckwheat sprout showed inhibition rate of 80.6% against the mutagenesis induced by N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) in Salmonella typhimurium TA100 strain. Also the ethyl acetate fraction (200 ${\mu}/plate$) showed higher antimutagenic activity than other fractions against the mutagenesis induced by 4-nitroquinoline-1-oxide (4NQO) in Salmonella typhimurium TA98 and TA100. In addition, the ethyl acetate fraction (200 ${\mu}/plate$) showed high antimutagenic effect of 80.9% and 85.9% against the mutation of TA98 and TA100 strains induced by 3-amino-1,4-dimethyl-5H-pyrido-(4,3-b)indol (Trp-P-1), respectively. The cytotoxic effects of each solvent fraction from the ethanol extract of buckwheat sprout against human cancer cell lines including lung carcinoma (A549), gastric carcinoma (AGS), breast adenocarcinoma (MCF-7), hepatocellular carcinoma (Hep3B), and colon adenocarcinoma (Colo 205) were investigated. The ethyl acetate fraction of buckwheat sprout ethanol extract at the concentration of 1.0 mg/ml showed strong cytotoxic activities of 70.3, 94.8, 79.6, 82.3, and 73.2% against A549, AGS, MCF-7, Hep3B and Colo 205 cancer cell lines, respectively.

메밀싹 에탄올 추출물의 항돌연변이 실험 결과, 직접변이원인 MNNG를 처리한 S. typhimurium AT100 균주에 대해 메밀싹 에탄올 추출물의 에틸아세테이트 분획(200 ${\mu}g/plate$)이 80.6%로 가장 높은 억제율을 보였으며, 4NQO를 처리한 TA98 및 TA100 두 균주 모두 에틸아세테이트 분획에서 다른 분획보다 높은 85% 이상의 돌연변이 억제율을 나타내었다. Trp-P-1에서는 TA98과 TA100 두 균주 모두 에틸아세테이트 분획물이 각각 80.9와 85.9%의 억제율을 나타내었다. 암세포 성장 억제 효과를 검토한 실험에서는 A549 와 Colo 205 세포에 1.0mg/ml 농도의 에틸아세테이트 분획물 처리 시 모두 70.3% 이상의 증식 억제효과를 보였으며, MCF-7 과 Hep3B 세포의 경우 부탄올과 에틸아세테이트 분획(1.0mg/ml)에서 80% 이상의 암세포 성장억제효과를 나타내었다. 특히, AGS는 1.0mg/ml농도의 에틸아세테에트와 부탄올 분획물에서 90% 이상의 강한 암세포 성장 억제효과를 나타내었다.
