신나무(Acer ginnala Max.) 껍질의 메탄올 추출물 및 분획물들의 Ames test를 이용한 항돌연변이원성 및 SRB assay에 의한 세포독성 효과를 규명하였다. 시료자체는 돌연변이원성이 없는 것으로 나타났다. MNNG ()에 대한 항돌연변이 효과에서 S. typhimurium TA100 균주에 대해 신나무 껍질 메탄올 추출물에서 시료농도 첨가시 로 가장 높게 나타났다. 동일시료 농도에서 4NQO에 대하여서는 S. typhimuri

In the present study, we investigated the antimutagenic and cytotoxic effects of Acer ginnala Max. bark extract on S. typhimurium TA98, TA100 and cancer cell lines with Ames test and SRB assay, respectively. They were extracted with methanol and then fractionated using hexane, chloroform, ethyl acetate, butanol, and water to obtain the fractions. The inhibition rate of methanol () of Acer ginnala Max. bark extract in the Salmonella typhimurium TA100 strain showed against the mutagenesis induced by N-methyl-N'-nitro-N-nitrosoguanidine (MNNG). In addition, the suppression of methanol extract with same concentration of in the Salmonella typhimurium TA98 and TA100 strains showed inhibition against 3-amino-1,4-dimethyl-5H-pyrido-(4,3-b)indol (Trp-P-1), respectively. The cytotoxicity effects of Acer ginnala Max. bark extract against the cell lines with human lung carcinoma (A549), human gastric carcinoma (AGS), human hepatocellular carcinoma (Hep3B) and human breast adenocarcinoma (MCF-7) were inhibited with the increase of the extract concentration. The treatment of 1.0 mg/mL Acer ginnala Max. bark methanol extract of methanol showed strong cytotoxicities of against A549, AGS, Hep3B and MCF-7, respectively.
