This study was carried out to determine the antioxidative, antimutagenic, and anticancer effects of Rhodiola sachalinensis root using 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical donating method, Ames test and cytotoxicity, respectively. Rhodiola sachalinenis root were extracted with ethanol and then further fractionated to n-hexane, chloroform, ethyl acetate (EtOAc), butanol and water, stepwise. Among five fractions, the Etohc fractions showed the highest electron donating activities (14.3 $\mu$g/mL). The inhibition rate of ethanol extract (200$\mu$g/plate) of Rhodiola sachalinensis root in the S. typhimurium TA100 strain showed 89.1% inhibition against the mutagenesis induced by MNNG. In addition, the suppression of EtOAc fractions with same concentration of Rhodiola sachalinensis root in the S. typhimurium TA98 and TAI00 strains showed 89.7% and 91.5% inhibition against 4NQO, respectively. The suppressions under the same condition against B($\alpha$)P and Trp-P-1 in the TA98 and TA100 strains were 94.2% and 95.7%, and 92.3% and 93.8%, respectively. The cytotoxic effects of Rhodiola sachalinensis root against the cell lines with human lung carcinoma (A549), human hepatocellular carcinoma (HepG2), human gastric carcinoma (AGS) and human breast adenocarcinoma (MCF-7) were inhibited with the increase of the extract concentration. The treatment of 1.0 mg/mL Rhodiola sachalinensis root of EtOAc fraction showed strong cytotoxicities of 90.5%, 81.5%, 92.2% and 82.6% against A549, HepG2, AGS and MCF-7, respectively.
