Panax ginseng CA Meyer, a herb from the Araliaceae, has traditionally been used as a medicinal plant in Asian countries. Ginseng extract fermented by ginsenoside-${\beta}$-glucosidase treatment is enriched in ginsenosides such as Rh2 and Rg3. Here we show that a fermented ginseng extract, BST204, has anti-proliferative and anti-invasive effects on HT-29 human colon cancer cells. Treatment of HT-29 cells with BST204 induced cell cycle arrest at $G_1$ phase without progression to apoptosis. This cell cycle arrest was accompanied by up-regulation of tumor suppressor proteins, p53 and p21$^{WAF1/Cip1}$, down-regulation of the cyclin-dependent kinase/cyclins, Cdk2, cyclin E, and cyclin D1 involved in $G_1$ or $G_1/S$ transition, and decrease in the phosphorylated form of retinoblastoma protein. In addition, BST204 suppressed the migration of HT-29 cells induced by 12-O-tetradecanoylphorbol-13-acetate, which correlated with the inhibition of metalloproteinase-9 activity and extracellular signal-regulated kinase activity. The effects of BST204 on the proliferation and the invasiveness of HT-29 cells were similar to those of Rh2. Taken together, the results suggest that fermentation of ginseng extract with ginsenoside-${\beta}$-glucosidase enhanced the anti-proliferative and the anti-invasive activity against human colon cancer cells and these anti-tumor effects of BST204 might be mediated in part by enriched Rh2.

Allium hookeri, a member of the onion family, has long been mainly cultivated for food and medicinal use in Southeast Asian countries, owing to its various biological properties. However, no studies of the anti-oxidative effects of fermented A. hookeri root extracts have been conducted to date. Therefore, this study investigated the effect of different starter cultures on the antioxidant activities of hot water extract of A. hookeri root by using the following five strains: Lactobacillus acidophilus, Bifidobacterum longum, Enterococcus faecium, Streptococcus thermophilus, and Saccharomyces cerevisiae. DPPH and ABTS radical scavenging activity, total phenolic acid contents, and total antioxidant capacity were higher in the hot water extract of A. hookeri root fermented with starter cultures than those of A. hookeri root. Among hot water extract of A. hookeri root fermented with starter cultures, fementing with S. cerevisiae showed the highest antioxidant activities. The results of this study provide new evidence of the anti-oxidative properties of A. hookeri root with starter cultures, indicating that it may be highly valuable as a natural product owing to its high-quality functional components.

GABA (γ-aminobutyric acid) has various beneficial effects on human health such as anti-hypertension, diuretic, tranquilizer, sleep induction and anti-stress functions. In this study, the properties and the antioxidizing effects of a fermented solution was investigated by applying GABA producing lactic acid bacteria (LAB) from kimchi to corn silk extract. Lactobacillus plantarum LAB459 was identified by physiological properties, carbohydrate fermentation pattern and 16s rRNA sequence analysis. Also, the GABA production ability of the separated L. plantarum LAB459 was confirmed through TLC and HPLC analysis. Moreover, from the fermentation of corn silk extract with skim milk, it was revealed that approximately 1 ㎍/mg of GABA produced by lyophilized ferments was yielded. Lastly, the flavonoid content and DPPH radical scavenging activity were found to be high in the lyophilized ferments than in the aqueous extracts. Therefore, L. plantarum LAB459 is considered to be used as a starter culture for various fermented foods or in food and medicinal materials.

Dodok (Codonopsis lanceolata Bench. et Hook) root contains abundant pharmaceutical substances and is widely used as a food and a medicinal herb. To identify the major components, fermented Codonopsis lanceolata was analyzed for its chemical compositions prior to their pharmaceutical substances, which were used as the fundamental data. The contents of carbohydrate, crude protein, crude lipid and ash are 79.3%, 13.0%, 2.40% and 5.3%, respectively. The calories of fermented Codonopsis lanceolata was 390.5 kcal. Total dietary fiber was 47.4% of total carbohydrates. The protein was composed of 18 different amino acids. The contents of essential and non-essential amino acids were 8,118.18 mg and 10,913.42 mg. The K was the largest mineral followed by P, Ca and Mg, which means fermented Codonopsis lanceolata is alkali material. The contents of saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids were 37.76%, 3.84%, and 35.64%, respectively. Therefore, the amount of the total unsaturated fatty acid was higher than that of any other plant. The content of crude saponin in fermented Codonopsis lanceolata was 60.1 mg/g. It is expected that a follow up study on fermented Codonopsis lanceolata through development and evaluation of processed foods for their functional properties would provide useful information as a source of medicinal foods.

The purpose of this study was to develop a mouthwash product with solid fermented oriental medicinal herb (OMH). Solid fermentation of magnolia, liquorice, and cnidium by Phellinus linteus mycelium was carried out successfully when 30% water was added to the medium, whereas 10% brown rice powder was required as an extra nutrient for solid fermentation of mint besides water. The amount of total phenol compounds and DPPH radical scavenging activity of OMH increased significantly (P<0.05) upon solid fermentation. Anti-microbial activities of fermented OMH also increased and were approximately 100-fold greater than those of unfermented samples. Oral pathogens such as Staphylococcus epidermis, Streptococcus pyogenes, Candida albicans, or Streptococcus mutans were used for determination of anti-microbial effects of OMH. Formulation of the mouthwash was developed based on the results of the sensory evaluation. Among seven formulas, the best formula chosen by the sensory evaluation was as follows: mouthwash prepared with 0.075% ethanol extract of solid fermented OMH as a main ingredient, 83.64% hot water extract of mint and clove (100:15, v/v) as a mouthwash base component, and other miscellaneous ingredients, including sodium fluoride, menthol, and surfactants. Data from a consumer's preference test with 30 participants, overall acceptance, and willingness to buy the product developed in this study were all significantly higher for the tested mouthwash compared to mouthwash on the market manufactured with OMH but with a different formula. Duration of freshness of the mouthwash after usage as determined by Breath Checker was not significantly different between the two samples, although the duration of our product was slightly longer than that of the commercial product mentioned above.

Hemp seed (Cannabis sativa L.; HS), an annual herbaceous plant in the Cannabis genus, has been reported to play various biological functions in immunity increase, atherosclerosis, constipation, hyperlipidemia prevention, anti-inflammatory, and anti-cancer. In recently years, as superfood, the growing interest in the health care benefits of hemp seed has led to increased consumption. In this study, we investigated the effect of an ethanol extract of HS fermented with lactic acid bacteria (Lactobacillus plantarum KCTC 3107, L. plantarum KCTC 3108, L. brevis BHN-LAB128, L. paracasei BHN-LAB129). An antibacterial activity against Staphylococcus aureus and Bacillus cereus were 13.99 mm and 15.17 mm, respectively. The ethanol extracts of fermented hemp seed by lactic acid bacteria that the contents of total polyphenol, total flavonoid content, DPPH radical scavenging activity, SOD-like activity, and ${\alpha}$-glucosidase inhibitory activity were increased compared to non-fermented hemp seed. Also, tyrosinase inhibitory activity of the fermented hemp seed (FHS), known to melanin increasing substance was increased. In these results, we suggested that FHS have effects of anti-oxidant, ${\alpha}$-glucosidase inhibitory activity, and tyrosinase inhibitory activity. Hence, we proposed that FHS has possible to development as functional foods and cosmetics.

Barley (Hordeum vulgare L.), of the Poaceae/Gramineae family, is a common grain in the surrounding area. It has been used in Ancient Egyptian medicine and it has been used worldwide for many years as food and as an ingredient in beer. Barley has been reported to have anti-inflammatory, anti -carcinogenic and anti-diabetic effects. So far, a lot of research has been done on barley but the effects of fermented barley seeds with lactic acid bacteria have not been studied largely. In this study, we investigated the effects of ethanol-extracted barley seeds after their fermentation with lactic acid bacteria. The biological activities of fermented barley seeds with lactic acid bacteria and non-fermented barley seeds were analyzed for total polyphenol content, total flavonoid content, DPPH radical scavenging, superoxide dismutase-like activity and tyrosinase inhibition. These results showed that fermented barley seeds with lactic acid bacteria have more advanced anti-oxidant and whitening properties than non-fermented barley seeds. Hence, we suggest that fermenting barley seeds with lactic acid bacteria can be an impressive material in the food and cosmetic industries.

Objective : This study set out to combine the treatment efficacy of Taraxacum with Dongchimi fermentation and investigate Taraxacum's effects on protection of liver cell and controlling nitric oxide(NO) through experiments, thus checking whether it had values as a physiological active matter. The experimental materials include Taraxacum Dongchimi (TD) and Taraxacum fermented by Dongchimi (TDF). As for methodology, experiments were carried out to compare TD and TDF in components, protection effects for liver cells, anticancer effects on liver cells, and protection effects for brain cells in the aspects of liver function and immunity enhancement. Method : The experimental materials include Taraxacum Dongchimi (TD) and Taraxacum fermented by Dongchimi (TDF). As for methodology, experiments were carried out to compare TD and TDF in components, protection effects for liver cells, anti-cancer effects on liver cells, and protection effects for brain cells in the aspects of liver function and immunity enhancement. Results : As shown in the chromatogram results, each valid component content increased in Taraxacum fermented by Dongchimi (TDF) for each time section. Of them, the valid component content at 36.80 minutes was approximately 2.7 times higher in TDF at 21.8% than in Taraxacum Dongchimi (TD) at 8.28%. TDF generated more excellent protection effects against the toxicity that caused oxidative damage to the liver cell(HepG2) with t-BHP than TD. The survival rate was low in TD of $100{\mu}g/m{\ell}$ and $300{\mu}g/m{\ell}$ and increased to 23.3% in TDF of $100{\mu}g/m{\ell}$. The survival rate was the highest at $300{\mu}M$ with a significant difference of 68.1%(P<0.05). Both TD and TDF showed effects of controlling nitric oxide production according to concentration with TDF recording a higher rate of controlling nitric oxide production than TD. There were significant differences(P<0.05) in the effects of controlling nitric oxide production at 200 ug/ml, 400 ug/ml in both groups. Especially the result TDF of $400{\mu}g/m{\ell}$ was thus similar to those of butein, the positive control group. Conclusion : The result of this studies is that Taraxacum fermented by Dongchimi (TDF) increased the valid component content compared with the simple mixture(TD). The findings clearly show that it is a material with the effects of improving immunity and liver cell protection. If fermentation methods are further developed to use it as a functional material, it will be subject to more opportunities of being used in other functional foods and make a contribution to integrated medicinal food development.

Imwonshibyukji(1827) is an important and stupendous ancient scientific book, which is much like an encyclopedia, that can discern the dietary life of the latter period of Choseon. This article is assorted, which is mentioned in this book, as Cho(Misutkaru-in parched grain that is weed out into powder) to the main material of grain Youmicho, Wandoocho, Youcho, also the medicinal plant as the main material Youkhangcho, Backyupcho, Chungumcho, Unyoungcho, and Naecho, Haengcho, Eicho, Imgumcho, Joyou, Bokbunjacho, made by fruit. The results of inquiring the property by the assortment is as you see in the following. Youmicho, Wandoocho, Youcho, Youkhyangcho, Backyupcho, and Chungumcho, which consist of glutinous rice, nonclutinous rice, barley, buckwheat, pea, and black soybean are among 13 kinds of methods to make Cho. The manufacturing process is similar to that of Misutkaru, but in the case of Unyoungcho 6 different medicinal powders are mixed with Chundang and Sookmill to form a hard portable taffy substance, which is quite unique. Naecho, Haengcho, Eicho, Imgumcho, Joyou, and Bokbunjacho are extracted from pulp and processed in a powder form like Misutkaru, which can also be considered as a fruit tea. Youcho is unique in its sense, since it is fermented by maggots that are bred in order to obtain the juice. Cho is known to calm thirst and empty stomachs, and has various medicinal materials to act as food to aid virility. It is also known to have multiple functions as an alternative staple, refreshment to aid virility, portable food, and preferable beverage. There are ten references on Cho, 37% are Korean in Ongheejobji and 63% Chinese in Jaeminyosool, Bonchogangmok, Chungmoonbobang, Nongjungchunsuh, Wangshinongsuh, Shikgyung, Sukmyung, Bonchoseupyou, and Wisaengbogam. The citations are in the general introduction and 13 types of Cho are cited 19 times overall, but citations based on Chinese references are non existe.

In order to develop a new traditional liquor by using Paecilomyces japonica, alcohol fermentation condition was investigated. Ethanol was produced maximally when 1% P. japoniea and 10% koji were added into mash and fermented by Saccharomyces cerevisiae at $25^{\circ}C$ for 15 days. Sensory evaluation and physiological functionalities of P. japonica traditional liquors made by different addition ($0.1{\sim}2.0%$) of the fungus were also determined and compared. As 0.1% P. japonica was added to mash, the liquor was best acceptable, and its fibrinolytic activity and nitrite scavenging activity were 11.2U and 19.8%, respectively.
