This study was conducted to investigate the effect of mycelia of Lentinus edoes mushroom-cultured Lonicera japonica Thunberg (LLJ) on proliferation of the cancer cell lines (Hep3B, MCF-7 and HeLa), sarcoma 180 (S-180) and antiallergy. In an anti-cancer test using Hep3B (hepatic cancer cell), MCF-7 (breast cancer cell) and HeLa (uterine cancer cell), LLJ extract showed higher antiproliferating effect than that of LJ (Lonicera japonica Thunberg) extract. In an anti-cancer testing using Hep3B cells, LLJ extract showed growth-inhibitory effect of $85.60{\pm}4.66%$ at 3mg/rnL. In an anti-cancer testing using MCF-7 cells, LLJ and LJ extracts showed high antiproliferating effect. LLJ showed the tumor suppressive effect in mice injected with S-180 cells. The growth-inhibitory rates against tumor cells were 61% for LLJ, 37% for LJ. LLJ inhibited histamine release from rat peritoneal mast cells activated by compound 48/80. These results suggest that Lentinus edodes mushroom-cultured herb has an antiproliferating effect against cancer cell lines (Hep3B, MCF-7 and HeLa) and S-180 tumor, and will be beneficial in the treatment of allergic reaction.

In this study, we evaluated antioxidant and antiproliferating effects of Setaria italica extract (SIE), Panicum miliaceum extract (PME) and Sorghum bicolor extract (SBE). Antioxidant effects of these extracts were determined by assessing DPPH radical scavenging activity, $ABTS^+$ radical scavenging activity, reducing power and superoxide dismutase (SOD)-like activity. From high concentrations ($1,000{\mu}g/mL$) of each extract at DPPH radical scavenging activities of SIE, PME and SBE were 10.5%, 5.5% and 86.8% respectively, $ABTS^+$ radical activities were 4.92%, 5.9% and 62.3% respectively, reducing powers (OD 700) were 0.15, 0.18 and 1.7 respectively, and SOD-like activities were 17.0%, 15.9% and 38.6% respectively. In addition, SBE significantly decreased the cell viability of androgen-sensitive lymph node metastasis type of prostate cancer (LNCaP) cells in a dose-dependent manner. Morphological study of SBE-treated LNCaP cells revealed distorted and shrunken cell masses. SBE-induced cell death was confirmed by observation of nuclear condensation and increased formation of apoptotic bodies. The antiproliferative effect of SBE seems to be associated with the antioxidant activity of its polyphenol content. The results of this study indicate that SBE can exert antioxidant and antiproliferative effects and may be as a useful food material.

This study was conducted to investigate the effect of mycelia extracts of mushroom-cultured ginseng by-product on electron donating ability and proliferation of hepatic cancer cell (Hep3B) lines and sarcoma 180(S-180). The ginseng by-product was obtained from ginseng residues generated in processing of ginseng water extract. Mushroom strains used for preparation of mushroom mycelia cultured with ginseng residue were Phellinus linteus, Ganoderma lucidum, Coriolus versicolor and Lentinus edodes. The electron donating abilities of the test samples were increased in a dose-dependent manner in the range of 500ppm to 10,000ppm, and Coriolus versicolor extract showed the most potent activity among four mycelia extracts. In an anti-cancer test using Hep3B cells, ethanol extract showed higher antiproliferating effect than water extract. Ethanol extract of Lentinus edodes showed growth-inhibitory effect of 99.1% at 5,000ppm. All of mycelia extracts of mushroom showed the tumor suppressive effect in mice injected with S-180 cells. The growth­inhibitoy rates against tumor cells were 59% for Phellinus linteus, 61% for Ganoderma lucidum, 65% for Coriolus versicolor, 56% for Lentinus edodes. In conclusion, these results suggest that mycelia extracts of mushroom cultured with ginseng by-product have an antiproliferating effect against Hep3B cell and S-180 tumor cells.

Under the active search for biologically active novel agents for cancer prevention and treatment, some agents have been found from plants which are easily available. Our previous research on them revealed that C. annuum L. var. angulosum Mill have high antiproliferating effect on cancer cells. However, it has not been known whether the anticancer efficacy is different according to each part of C. annuum L. var. angulosum Mill or whether it can be changed by timing of harvest or solvent for extraction. Thus we compared the efficacy of each part of C. annuum L. var. angulosum Mill and assessed how much difference in the efficacy can be made according to the time of harvest or solvents for extraction. We observed the morphologic change and apoptosis 48 hr after treatment with the extract of each part of C. annuum L. var. angulosum Mill in MCF-7 mammary gland adenocarcinoma cells and human hepatoma cells. We also counted cancer cells by trypan blue method and MTT method to check the cytotoxicity. The leaf extract showed the highest anticancer effect among all the parts of C. annuum L. var. angulosum Mill; 50％ and 70％ reduction in the number of cancer cells was observed at 25 $\mu\textrm{g}$/mι and 50 $\mu\textrm{g}$/mι, respectively. It was more than 2 times as potent as 5-fluorouracil (5-FU). We found chromosomal fragmentation, clumping, and destuction by PI staining, and DNA fragmentation by electrophoresis. In conclusion, this study suggests that leaf extraction using water as solvent has the highest antiproliferative and apoptotic activity in cancer cells compared with other parts of extraction.

This study was performed to investigate the effect of the water-extract from non-fermented or fermented Chaga mushrooms (Inonotus obliquus) on the proliferation and apoptosis of the NIH3T3 mouse normal fibroblast cells and various human cancer cell lines including HCT-15 human colon carcinoma, AGS human gastric carcinoma, MCF-7 human breast adenocarcinoma, Hep3B human hepatocellular carcinoma and HeLa human cervical carcinoma using MTT(3-[4,5-dimethylthiazol-2-yl] -2,5-diphenyl tetrazolium bromide) assay and DNA fragmentation. In an anti-cancer test using various human cancer cells, fermented Chaga mushroom extract showed higher antiproliferating effect than that of non-fermented Chaga mushroom extract. Mouse normal NIH3T3 cells were exhibited 80% above survival under fermented or non-fermented Chngn mushroom extract of various concentrations(0, 0.5 and 1 mg/ml). Fermented Chaga mushroom extract significantly inhibited cell growth on HCT-15 cells in a dose-dependent manner. HCT-15 cells treated with non-fermented or fermented Chaga mushrooms extract produced a distinct oligonucleosomal ladder with different sizes of DNA fragments, a typical characteristic of cells undergoing apoptosis. These results suggest that fermented Chaga mushroom extract suppresses growth of HCT-15 human colon carcinoma cells through apoptosis.

The present study was performed to evaluate the anti-oxidant and anti-proliferating activity of the water extract mixture of Cordyceps militaris (CM) and Allium tuberosum (AT). The water extract mixture rate of CM and AT was optimized by means of a sensory evaluation test. The optimized mixture rate were decided at 70% of CM, 30% of AT, and 10% of apple concentrate as an additive. The values of total acidity, pH, sugar contents, and turbidity of the water extract mixture were 0.1%, 4.28, 9.10 °Brix, and 1.48 respectively. The water extract mixture had effective DPPH radical scavenging activity, reducing power effect, and ABTS radical activity. DPPH radical activities of the water extract and the water extract mixture were 43.2% and 51.7% respectively; their reducing power (OD₇₀₀) was 1.14 and 1.43 respectively; and ABTS^.+ radical activities were 47.1% and 62.2% respectively. Also, the water extract mixture showed a higher anti-proliferating effect than the AT extract on human prostate cancer cells. These results provided experimental evidence that the water extract mixture of CM and AT is a better source of anti-oxidant and anti-cancer ingredients than a single extract of CM. In conclusion, the water extract mixture of CM and AT will be beneficial in development of a functional drink.

Prunus mume Sieb. et Zucc is widely distributed in East Asia (Korea, Japan, and China), and its fruit is often used as a medication and food material. However, because most previous studies have only investigated the state of Prunus mume fruit extract, studies on the various ways of processing this extract are still needed to increase its utilization. In this study, we evaluated the physicochemical properties and physiological activities of spray-dried Prunus mume vinegar powder (SPP). The sugar content, pH, total acidity, and moisture content of the SPP were 8.90 °Brix, 3.19, 1.05%, and 3.07%, respectively. The SPP exhibited significantly high antioxidant activity in terms of DPPH radical scavenging activity (65.55%), reducing power (1.48), and hydrogen peroxide scavenging activity (48.07%). In addition, the SPP remarkably decreased the cell viability of human breast MDA-MB-231 and human skin cancer SK-MEL-28 in a dose-dependent manner. The morphological results of the treatment of MDA-MB-231 cells with SPP were distorted, shrunken cell masses. Furthermore, apoptotic bodies and nuclear condensation formed in the SPP-treated MDA-MB-231 cells. The total polyphenol and flavonoid contents of the SPP were 59.58 ㎍/g (gallic acid equivalent) and 57.56 ㎍/g (quercetin equivalent). The results of this study indicate that SPP, which has antioxidant activity and anticancer effects, can be useful in the development of natural medicines and functional food ingredients.

This study was conducted to investigate the anticancer (in vitro) and antiallergy effects of rice bran extracts. In an anticancer test using Hep3B cells and HeLa cells, water and 60% ethanol extracts of rice bran inhibited the growth of Hep3B and HeLa cell lines and morphological changes were also observed. In Hep3B cell lines, water extract of rice bran showed a higer antiproliferating effect than 60% ethanol extract. The growth-inhibitory effect against HeLa cells were 30.9% for $1,000{\mu}g/mL$, 88.8% for $3,000{\mu}g/mL$ rice bran water extract. The expressions of $Fc{\varepsilon}RI$ mRNA and c-kit in HMC-1 (human mast cell) were decreased by 60% ethanol treatment but tryptase mRNA was not changed. The extracts of rice bran inhibited histamine release from RPMC (rat peritoneal mast cell) activated by compound 48/80. Rice bran water extract showed inhibitory effect of 87% at $0.01{\mu}g/mL$ concentration and 60% ethanol extract inhibited the release of histamine by 86% at $100{\mu}g/mL$ concentration.
