This study was carried out to investigate the mutagenic, antimutagenic, cytotoxicity and antitumor effect of Codonopsis lanceolata (CL). CL was extracted with 70% ethanol and then further fractionated to hexane, chloroform, ethyl acetate, butanol and water. Antimutagenic, cytotoxicity and antitumor effects of CL extracts were measured by using Ames test, SRB method, and the tumor growth inhibition test. CL extracts did not show any mutagenicity in the Ames test; however, 70% ethanol extracts and its fractions had strong antimutagenic effects against mutation induced by N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) and 4-nitroquinoline-1-oxide (4NQO). The ethyl acetate fraction of CL (200 ${\mu}g$/plate) showed approximately 72.1% inhibitory effect on the mutagenesis induced by 4NQO against TA98 strain, whereas 69.6% and 67.0% inhibitions were observed on the mutagenesis induced by MNNG and 4NQO against TA100 strain. In anticancer effects, the cytotoxicity of CL extract and its fractions against cancer cell lines including human cervical adenocarcinoma (HeLa), human hepatocellular carcinoma (HepG2), human breast adenocarcinoma (MCF-7), human lung carcinoma (A549) and transformed primary human embryo kidney (293) were investigated. The treatment of 1 mg/mL CL ethyl acetate fraction had the highest cytotoxicity of 74.5%, 70.7% and 80.3% against HeLa, MCF-7 and A549 cells, respectively. In contrast, the extract and its fractions showed only 2$\sim$31% cytotoxicity for a normal human kidney cell line (293). In vivo anticancer effect of CL extract was tested using Balb/c mice transplanted sarcoma-180 cells. CL ethyl acetate fraction showed the highest inhibition rate of 56.4% at the 50 mg/kg concentration.

This study was performed to determine the antimutagenic and anticytotoxic effects of soybean paste (doenjang) added deep sea water salt and see tangle in Salmonella Typhimurium TA98, TA100 and human cancer cell lines. In the Ames test, methanol extract of doenjang did not exhibit any mutagenicity but showed substantial inhibitory effects against mutation induced by N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) and 4-nitroquinoline-1-oxide (4NQO). The methanol extracts of doenjang ($200{\mu}g$/plate) added deep sea salt and see tangle (doenjang C) showed approximately 89.1% and 70% inhibitory effect on the mutagenesis induced by MNNG and 4NQO against TA100 strain, whereas 84.4% inhibitions were observed on the mutagenesis induced by 4NQO against TA98 strain. The cytotoxic effects of doenjang methanol extracts against the cell lines with human cervical adenocarcinoma (HeLa), human hepatocellular carcinoma (Hep3B), human gastric carcinoma (AGS), human lung carcinoma (A549) and human breast adenocarcinoma (MCF-7) were inhibited with the increase of the extract concentration. The treatment of 1.0 mg/mL doenjang C of methanol extracts showed strong cytotoxicities of 71%, 74.4%, 66.2%, 77.3%, and 71.2% against HeLa, Hep3B, AGS, A549, and MCF-7, respectively. In contrast 1 mg/mL treatment of doenjang C methanol extracts had only $10{\sim}40%$ cytotoxicity on normal human embryonal kidney cell (293). Doenjang methanol extract inhibited significantly the tumor growth in mice injected sarcoma-180 cells. Especially, doenjang C methanol extract showed an inhibition of tumor cell activity of 33% by the administration of 25 mg/kg methanol extracts.

This study was performed to measure the antioxidative, antimutagenic, and cytotoxic properties of Prunus armeniaca using the DPPH (1, 1-diphenyl-2-picrylhydrazyl) free radical donating method, the Ames test, and cytotoxicity measurements, respectively. Electron-donating abilities were 48.3, 43.9, 14.8 and 12.9 per g dry matter of P. armeniaca seed (PAS), P. armeniaca flesh(PAF), butylated hydroxytoluene, and ${\alpha}-tocopherol$, respectively. The direct antimutagenic effects of an ethanol extract of P. armeniaca were examined in Ames tests using Salmonella typhimurium TA98 and TA100 as reporter organisms. In the Ames test, the ethanol extract of P. armenicaca alone did not exhibit any mutagenicity but the extract did show substantial inhibitory effects against mutations induced by N-methyl-N'-nitro-N-nitrosoguanidine(MNNG) and 4-nitroquinoline-1-oxide(4NQO). The ethanol extract of PAS(200g dry matter/plate) inhibited strain TA98 mutagenesis induced by 4NQO by ca. 37.9%, and mutation inhibition values of 42.1% and 69.4%, respectively, were observed when 4NQO and MNNG acted on the TA100 strain. The cytotoxic effects of ethanol extracts of P. armeniaca against cell lines of human lung carcinoma(A549), human breast adenocarcinoma(MCF-7), human hepatocellular carcinoma(Hep3B), human cervical adenocarcinoma(HeLa), and human gastric carcinoma(AGS) rose with increases in extract concentration. An ethanol extract(4mg/mL dry matter) of PAF showed strong cytotoxicities of 88.2%, 58%, 72.8%, 89.4%, and 91.9% against A549, AGS, MCF-7, HeLa, and Hep3B cells, respectively. In contrast, the same extract showed only 13 37% cytotoxicity for a nomal human kiney cell line(293). It is suggested that P. armeniaca possesses useful antioxidative, antimutagenic, and anticancer properties.

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 ($200\;{\mu}g/plate$) of Acer ginnala Max. bark extract in the Salmonella typhimurium TA100 strain showed $83.3\%$ 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 $80.3\%\;and\;92.7\%$ 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 $77.3\%,\;90.4\%,\;88.9\%,\;and\;83.7\%$ against A549, AGS, Hep3B and MCF-7, respectively.
