  • The growth inhibitory effects of kimchi prepared with solar salt were investigated. Chinese cabbages were brined with purified salt, four year-old solar salt, and Topan solar salt, and then mixed with other ingredients. The final salt concentration was adjusted to 2.2~2.4% (w/v) for each salt, and the kimchi was fermented at $7^{\circ}C$. When the acidity reached around 0.5~0.6%, the kimchi was used as a sample for further experimentation. MTT assay was used to measure the growth inhibitory effect of kimchi extracts (water, methanol) on BJ human foreskin normal cells, AGS human gastric adenocarcinoma cells, and HT-29 human colon carcinoma cells. Water extracts of all the kimchi samples showed growth inhibitory effects on cancer cells; however, there was no significant difference among the used salts. Methanol extracts of all the kimchi samples showed higher growth inhibitory effects compared to the water extracts. The methanol extracts of four year-old solar salt kimchi (AGS: 73%, HT-29: 48%) and Topan solar salt kimchi (AGS: 62%, HT-29: 46%) showed higher growth inhibitory effects than that of purified salt kimchi (AGS: 52%, HT-29: 39%). In addition, morphological changes of cancer cells (AGS, HT-29) and decreased cell numbers were observed when methanol extract of four year-old solar salt kimchi was treated to AGS and HT-29 cells. However, none of the kimchi extracts showed any growth inhibitory effect on BJ normal cells.

  • This study compared the cytotoxic effect of extracts from four different sea bream species (Pagrus major, Acanthopagus schlegeli, Oplegnathus fasciatus, and Girella punctata) in human cancer cell lines. Cytotoxic activity against the growth of human gastric adenocarcinoma (AGS) and HT-29 human colon cancer cell lines was determined using a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Treatment with acetone/methylene chloride (A+M) and methanol (MeOH) extracts from the four sea bream species dose-dependently increased cytotoxicity against the growth of AGS and HT-29 cancer cells (p < 0.05). As shown by a cell viability assay, treatment with A+M and MeOH extracts from red sea bream (P. major) had the highest cytotoxic effect (p < 0.05) among the sea bream species. The IC50 values of an 85% aqueous methanol (85% aq. MeOH) fraction from red sea bream (P. major) against AGS and HT-29 cancer cells was 0.33 and 1.58 mg/ml, respectively, suggesting that the 85% aq. MeOH fraction had the highest cytotoxic effect among the fractions (p < 0.05). Our results demonstrate that four different sea bream species exhibited cytotoxic activity, as well as high-quality amino acids and fatty acids. Among the sea bream species, red sea bream (P. major) showed the greatest cytotoxic effect. The results could be used to improve nutrition information available to consumers.

  • Increased antimutagenic and in vitro anticancer effects were observed by the fermentation process during Kochujang manufacturing. In order to confirm the increased functionality, wheat grain, first fermented wheat grains (FFWG), second fermented wheat grains (SFWG), final fermented wheat grains (FiFWG), red pepper powder (RPP), and commercial Kochujang (CK) were prepared. Kochujang manufactured with final fermented wheat grains and red pepper powder were further fermented for 15 days and 30 days. The antimutagenic effects were determined by counting the number of revertants in Salmonella Typhimurium TA100 against N-methyl-N'-nitro-nitrosoguanidine (MNNG, 1.0mg/mL). The final fermented wheat grains (52% inhibition) showed higher antimutagenic effects than the wheat grain (34%), and the commercial Kochujang showed the highest antimutagenic effects (55%). We tested the inhibitory effect on the growth of HT-29 human colon carcinoma cells and AGS human gastric adenocarcinoma cells by using MTT (3-(4,5-dimethyl-thiazol)-2,5-diphenyltetrazolium bromide) assay. The results showed that increased fermentation process continually increased the growth inhibitory effect on both cancer cells. The further fermentation for 15 days of the Kochujang product also increased inhibitory growth of the AGS cancer cells. In conclusion, the methanol extract from fermented wheat grains and commercial Kochujang showed sequentially increased antimutagenic and in vitro anticancer activity, and thus the final commercial Kochujang revealed the highest effect.

  • This study was carried out to determine the inhibitory effects of methanol extracts from Korean Orysa sartiva and Coix lachryma-jobi var. ma-yuen on mutagenicity using Ames test and growth of AGS human gastric adenocarcinoma and HT-29 human colon cancer cells. Both treatments of methanol extracts (5 mg/assay) from Orysa sartiva and Coix lachryma-jobi var. ma-yuen to Ames test system inhibited aflatoxin $B_1$ ($AFB_1$) induced mutagenicity by 76%. In case of N-methyl-N'-nitro-N-nitrosoguamidine (MNNG) induced mutagenicity, the methanol extracts (5 mg/assay) from Orysa sartiva and Coix lachryma-jobi var. ma-yuen showed 79% and 69% inhibitory rate, respectively and the inhibitory effect was a little stronger in Orysa sartiva Inhibitory effects of methanol extracts from Orysa sartiva. and Coix lachryma-jobi var. ma-yuen on the growth of AGS and HT-29 human cancer cells were increased as dose dependent patterns and the inhibitory effects on AGS and HT-29 cells were similar. The above results indicate that the consumption of these cereals, which contain many nutrients with good quality, may be recommended as potent functional foods for improving health.

  • We investigated a method to improve anticancer activities of Acer mono by ultra high pressure extraction process. The extract yields by ultra high pressure were 9.49% and 9.87% for 5 min and 15 min processing time, respectively, which were relatively higher than 3$\sim$4% of conventional extraction processes due to their resid bark structure. The extract for 15 minutes extraction (HPE15) showed higher potent scavenging effect as 94.56% than the control, BHA as 93.24%. On SOD-like test, HPE15 also showed the highest activity as 38.6% at 1.0 mg/mL concentration. The cytotoxicity of HPE15 on normal human lung and kidney cell were below 23.54% in adding 1.0 mg/mL. Generally, human cancer cell growth stomach adenocarcinoma (AGS), lung adenocarcinoma (A549), breast adenocarcinoma (MCF-7), colon adenocarcinoma (Caco-2) and liver adenocarcinoma (Hep3B) were inhibited up to 75% with higher selectivity of above 4.0. High antioxidant activity of HPE15 resulted in high anticancer activity, and its activity was also due to higher yields of Acer mono by ultra high pressure extraction process. It was also proved by HPLC comparison analysis.

  • The growth inhibition effect of $Doenjang$ that was prepared with various kinds of solar salt was investigated. $Doenjang$ was prepared using the bacterial koji and five kind of salt with 12% salt concentration (w/w): purified salt $Doenjang$, one-year aged solar salt $Doenjang$, four-year aged solar salt $Doenjang$, topan solar salt $Doenjang$, and boiled solar salt $Doenjang$. The $Doenjangs$ were fermented and aged for 18 months. The growth inhibition effects of the water extracts and the methanol extracts of the $Doenjangs$ were measured on AGS human gastric adenocarcinoma cells, HT-29 colon carcinoma cells, and BJ human foreskin normal cells using MTT assay. The water and methanol extracts of the $Doenjang$ samples showed growth inhibition effects on the cancer cells, in the following order of the samples with the strongest to the weakest effect: the four-year aged solar salt $Doenjang$, the topan solar salt $Doenjang$, the boiled solar salt $Doenjang$, the one-year aged solar salt $Doenjang$, and the purified salt $Doenjang$. The methanol extracts of the four-year aged solar salt Doenjang (AGS: 55% and HT-29: 48%) showed the strongest growth inhibition effect. In addition, decreased cancer cell numbers and morphological changes in the cancer cells (AGS and HT-29) were observed when the methanol extract of the four-year aged solar salt $Doenjang$ was treated. None of the $Doenjang$ extracts showed a growth inhibition effect on the BJ normal cells, though.

  • In order to determine chemical components of onion flesh and peel, general nutrients, vitamin C, and total flavonoids were measured. Onion peel showed less moisture (14.3%) and no vitamin C compared to onion flesh. Onion peel contained more amounts of total flavonoids compared to onion flesh. In addition, the inhibitory effects of solvent extracts from onion flesh and peel on $H_2O_$-induced oxidative stress and growth of cancer cell lines (AGS human gastric adenocarcinoma and HT-29 human colon cancer cells) were investigated. Acetone with methylene chloride (A+M) and methanol (MeOH) extracts from onion flesh and peel appeared to significantly reduce the levels of intracellular reactive oxygen species (ROS) (p<0.05) and a greater antioxidant effect was observed in onion peel. Among fractions, 85% aq. methanol showed a higher protective activity against oxidative stress in both flesh and peel and there was no effect in the water and hexane fractions. The growth of cancer cells exposed to medium containing extracts and fractions from onion flesh and peel was inhibited dose-dependently. The growth of AGS was inhibited more in both flesh and peel compared to HT-29, and onion peel was more effective than onion flesh. Among fractions, 85% aq. methanol showed the greatest effect on growth inhibition in both flesh and peel. $IC_{50}$ values of 85% aq. methanol fraction from onion flesh and peel on AGS were 0.04 and 0.03 mg/ml, respectively, while those on HT-29 were 0.23 and 0.04 mg/ml. From our results, 85% aq. methanol fraction had an inhibitory effect against oxidative stress and growth of cancer cells, suggesting that it may contain biological active compounds.

  • 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.

  • This study was performed to determine the antioxidative, antimutagenic, and anticancer effects of vaporized liquid of water-boiled pine needle(VLP) using DPPH free radical donating method, Ames test, and cytotoxicity. VLP showed the highest electron donating activities $(18.4\;{\mu}L)$. The inhibition rate of VLP $(200\;{\mu}L/plate)$ in the Salmonella. typhimurium TA100 strain showed $45.9\%$ inhibition against the mutagenesis induced by MNNG. In addition, the suppression of with same concentration of VLP in the S. typhimurium TA100 strains showed $85.5\%$ inhibition against 4NQO, respectively. The suppressions under the same condition against Trp-P-1 in the TA98 and TA100 strains were $91.0\%$ and $62.1\%$, respectively. The cytotoxic effects of VLP against the cell lines with human lung carcinoma (A549), human hepatocellular carcinoma (HepG2) , human gastric carcinoma (AGS), human breast adenocarcinoma (MCF-7) and human cervical adenocarcinoma (HeLa) were inhibited with increase of the VLP concentration. The treatment of $50\;{\mu}L/well$ VLP showed strong cytotoxicities of $78.7\%,\;90.3\%,\;90.8\%,\;62.3\%$ and $93.7\%$ against A549, HepG2, AGS, MCF-7 and HeLa, respectively.

  • In this paper, we investigate to determine quality characteristics, fatty acid composition and cytotoxic effect of extracts and fractions from whole Lycopus lucidus Turcz. roots. Additionally, we evaluated cytotoxic activity against the growth of human fibrosarcoma cells (HT-1080) and human gastric adenocarcinoma (AGS), human colon cancer cell (HT-29) lines using a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Acetone+methylene chloride (A+M) and methanol (MeOH) extracts from L. lucidus Turcz. were obtained through solvent extraction. Then we further fractionated both extracts with n-hexane, 85% aq. MeOH, n-butanol (n-BuOH) and water. In fatty acid composition, L. lucidus Turcz. contained 33.2% of 18:1n-9 and 1.81% of 18:3n-3, respectively. The incorporation of treatment with A+M and MeOH extracts and n-hexane, 85% aq. MeOH, n-butanol (n-BuOH) and water fractions dose-dependently increased cytotoxicity against the growth of HT-1080 and AGS, HT-29 cancer cells (p<0.05). The A+M extract had a higher inhibitory effect on the growth of all cancer cells in comparison to MeOH extract. Among the fractions, the 85% aq. MeOH and n-hexane fractions showed a higher inhibitory effect after proliferating the three cancer cells. These results suggest that the 85% aq. MeOH and n-hexane fractions have a potential to inhibit the growth of human cancer cell lines.
