  • In this study, we investigated the effect of the amount of water added prior to fermentation on the quality of bokbunja (Rubus coreanus Miq.) wine produced. Water was added at 0-fold (A), 1-fold (B), 2-fold (C), 3-fold (D), and 4-fold (E) of the fresh bokbunja weight (w/w), prior to fermentation. Although the amount of bokbunja wine obtained after fermentation increased in proportion to the amount of water added prior to fermentation, the total acidity of the bokbunja wine, adjusted for the weight of bokbunja used in the fermentation process, increased. Moreover, the total phenol and flavonoid content (mg) per weight (g) of bokbunja, in (B), (C), (D), and (E) were 2.86-4.42 and 2.58-3.01 times higher, respectively, than those in (A). These data suggest that different types of bokbunja wines can be produced and different contents of total phenol can be obtained by simply changing the amount of water added prior to fermentation.

  • The fruit of the black raspberry (Rubus coreanus Miquel) has been employed in traditional medicine, and recent studies have demonstrated its measureable biological activities. However, the root of the black raspberry has not been studied. Therefore, in this study, we evaluated the anti-inflammatory and antibacterial properties of the root and unripe fruit polyphenols of the black raspberry. Both polyphenols proved to have anti-inflammatory activity as evidenced by the decreased nitric oxide (NO), cytokines (IL-$1{\beta}$, IL-6, and IL-10) and prostaglandin E2 ($PGE_2$) levels in lipopolysaccharide (LPS)-stimulated RAW 264.7 murine macrophages. However, root polyphenols showed stronger anti-inflammatory activity than fruit polyphenols. LPS-induced mRNA and protein expressions of inducible NO synthase (iNOS) and cyclooxygenase (COX)-2 levels were also decreased, confirming the anti-inflammatory activity. Root polyphenols showed lethal activity against methicillin-resistant Staphy-lococcus aureus (MRSA), carbapenem-resistant Acinetobacter baumannii (CRAB), and Bacillus anthracis. In contrast, the black raspberry fruit did not demonstrate these properties. These data provide the first demonstration that black raspberry root has potential anti-inflammatory and anti-superbacterial properties that can be exploited as alternatives for use in the food and cosmetic industries and/or as pharmaceuticals.

  • Bioconversion, the enzymatic process by microorganism on organic precursor to desired products. The natural extract is converted into a form that can be easily absorbed into the skin, while scaling up of to higher quantity is possible. Selection of naturally processed raw material rather than chemically processed is preferred. Therefore, fermentation was carried out by mixing Rubus coreanus Miquel, soybean, Zanthoxylum schinifolium as bioconverting materials, the possibility of inflammation, whitening material were checked. In this study, useful microorganisms were isolated from various salted fish, and 16S rDNA sequence was analyzed to confirm their genetic characteristics. Combining the three natural materials using bioconversion technology to study their activity before and after fermentation. To evaluate the antioxidant activity and the active ingredient content the DPPH radical scavenging activity and the total polyphenol content were examined. Raw 264.7 cells were used to evaluate MTT assay, NO and $TNF-{\alpha}$ production inhibitory activity. Also, to evaluate the whitening activity, tyrosinase inhibitory activity and melanin formation inhibitory activity were measured using B16F10 cells. In total 34 strains were obtained from various salted fish. The effective strains useful for the bioconversion process, showed that DPPH radical scavenging ability and polyphenol content were increased in the two kinds of microbial treatment groups compared to the untreated group. 16S rDNA sequencing analysis of the strains showed excellent in Pediococcus pentosaceus B1 in comparison. An increase of up-to 156% in anti-oxidative activity and 141% in polyphenol content was observed after bioconversion. In addition, after mixed fermentation the toxidty of Raw 264.7 and B16F10 cells tended to decrease and a significant increase was observed in anti-inflammatory activity as well. Also, tyrosinase activity and melanin significantly. synthesis decreased significantly.

  • Skin wrinkles typically appear as a result of aging processes. One of causes may be the nonenzymatic glycation followed formation of browning products called advanced glycation endproducts (AGEs), an irreversible cross-linked protein. The accumulation of glycated collagen cross-linked in skin inhibits the formation and function of skin tightening agents such as collagen and elastin. To development for anti-wrinkle ingredients from edible plants, MeOH and hot-water extracts were prepared and evaluated for their inhibitory effects of AGEs formation. The activities of both extracts from bay laurel (Laurus nobilis), cinnamon (Cinnamomum loureirii), clove (Eugenia caryophyllate), oregano (Origanum vulgare), rosemary (Rosemarinus officinalis), savory (Satureja hortensis) and star anis (Illicium verum) of western spices, and blackberry (Rubus coreanus), dayflower (Commelina communis), Epimedium koreamun (whole), termunalia frutus (Terminalia chebula) and turkestan rose (Rosa rugosa) of medicinal plants were higher than the others. Of Korean vegetables, however, MeOH and hot-water extract from only Asters caber and green tea showed higher activities, and no activity in Korean marine plants (seaweeds).

  • The inhibitory effect of Chung-Jang-Hwan (C-mix) consisted of Geranium nepalense subsp. thunbergii, Saururus chinensis, and Rubus coreanus were investigated in dextran sulfate sodium (DSS)-induced colitic mice by microarray analysis. Treatment with Cmix improved colitic symptoms, including colon shortening and myeloperoxidase activity. Treatment with DSS alone upregulated the expression levels of inflammation-related genes, including IL-$1\beta$, IL-6, CCL2, CCL4, CCL5, CCL7, CCL8, CCL24, CXCL1, CXCL2, CXCL5, CXCL9 and CXCL10, and other colitis-related genes such as COX-2, PAP, MMP family, S100a8, S100a9 and DEFA1 in mice. However, treatment with C-mix inhibited the expression levels of inflammation-associated genes induced by DSS. The increased expression levels of COX-2 and IL-$1\beta$, representative inflammatory genes, were confirmed by a quantitative realtime polymerase chain reaction analysis. These results indicate that C-mix may ameliorate colitis by the inhibitory regulation of inflammation-associated genes.

  • Ethanol extracts of 38 vegetables were subjected to an in vitro screening for their growth-inhibitory activities towards Bifidobacterium bifidum, B. longum, Clostridium perfringens, Lactobacillus acidophilus, L. casei, and Escherichia coli using paper disc agar diffusion methods under anaerobic conditions. The responses varied with both bacterial strain and vegetable species. In a test with 20 mg/disc, Zingiber officinale extracts showed significant growth-inhibitory responses against B. bifidum, and strong inhibitions against L. casei were detected in the extracts of Chrysanthemum coronarium var. spatiosum and Lactuca sativa. The extracts of Allium sativum, Capsicum annuum, L. esculentum, L. esculentum var. cerasiforme, and Z. officinale showed strong inhibitory activities against C. perfringens, while moderate growth-inhibitory responses were observed in the extracts of C. ffutescens, Cucurbita moschata, Daucus carota var. sativa, and Rubus coreanus. However, all vegetable extracts showed no inhibitions against B. longum, L. acidophilus, and E. coli. In tests with 5 mg/disc, moderate inhibitions were observed in the extracts of C. coronarium var. spatiosum and L. sativa against L. casei and Z. officinale against B. bifidum. Vegetables extracts, except for C. coronarium var. spatiosum, L. sativa, and Z. officinale, did not affect the growth of beneficial bacteria. Strong inhibitory responses against C. perfringens were detected in the extracts of C. annuum and L. esculentum var. cerasiforme. Daily intake of vegetables may be important in the prevention of human diseases caused by the intestinal bacteria.
