  • In order to fine antioxidant and whitening agent source from nature, the comparisons of antioxidative activity and tyrosinase inhibitory activity were carried out for various ethanol extract on Polygoni Multiflori Radix, Polygonati Rhizoma and Ephedrae Herba. Comparing for three ethanol extracts, the highest electron donating ability was found at Polygonati Rhizoma (86.6%), but, the highest SOD-like ability, at the Ephedrae Herba (47.8%). Xanthine oxidase experiment exhibited 95.7% of hindrance effect in Ephedrae Herba, and 84.0% in Polygonati Rhizoma. A tyrosinase inhibitory activity assay was conducted to evaluate the whitening effects of the extracts, The tyrosinase inhibitory activity was 6.5% in the Polygoni Multiflori Radix, 32.6% in the Polygonati Rhizoma, 64.0% in the Ephedrae Herba. Based on these results, we suggest that the ethanol extracts of Polygoni Multiflori Radix, Polygonati Rhizoma and Ephedrae Herba can be used as food and cosmetic ingredients.

  • Background: Astragali radix (A) and Lithospermi radix (L) have long been used as traditional medicines due to their known anti-inflammatory effects. This study aimed at evaluating, their optimal mixing ratio and their functional compounds by investigating the inhibitory effects of mixed extracts of A and L and their active compounds on matrix metalloproteinases (MMPs). Methods and Results: A and L extracts were obtained by extraction at $80^{\circ}C$ using 50% and 70% fermented alcohol, respectively, and then mixed at a ratio of 5 : 5, 6 : 4, 7 : 3 and 8 : 2 (w/w). The activities of MMP-1, MMP-3, and MMP-13 were evaluated in interleukin-1beta ($IL-1{\beta}$)-induced SW1353 cells. The extract mixtures showed synergistic inhibitory effects on MMP-3 and MMP-13, higher than the effects of the individual A and L extracts. The 7 : 3 mixture (ALM16) showed the most effective MMPs inhibitory activity, while among the active ingredients, calycosin-7-O-${\beta}$-D-glucoside and lithospermic acid exhibited excellent MMPs inhibitory activity. Additionally, an HPLC method was established for simultaneous quantification of the effective components of the extract mixtures, and validated by measuring the linearity, precision and accuracy of the limit of detection (LOD) and limit of quantification (LOQ). Conclusions: ALM16 showed the most effective MMPs inhibitory activity. Calycosin-O-${\beta}$-D-glucoside, calycosin and lithospermic acid were identified as useful candidates, as they were the major functional compounds in the MMP inhibitory activity. Summarily, ALM16 might be a highly effective in osteoarthritis management, owing to its because it exhibits a protective effect on cartilage via excellent inhibition of MMPs.

  • Mast cells play pivotal pathologic roles in allergic disease involving T helper 2 (Th2) cytokine such as interleukin (IL)-4 and IL-13. Fisetin has been known as an anti-allergic agent having inhibitory effects on the IL-4 and IL-13 gene expressions in inflammatory immune cells. However, its molecular mechanisms for suppressive effects of fisetin on IL-4 and IL-13 in activated mast cells have been incompletely elucidated. In this study we found that fisetin significantly inhibited the phorbol 12-myristate 13-acetate (PMA) and ionomycin (PI)-induced production of IL-4 and IL-13 in mast cells. The levels of mRNA were dramatically decreased by fisetin, indicating the suppression might be regulated at the transcriptional levels. Western blot analysis of the nuclear expression of various transcription factors involved in the promoter activation indicated that suppression of c-Fos was prominent together with significant down-regulation of nuclear factor of activated T-cell (NF-AT) and NF-${\kappa}B$, but not c-Jun. Furthermore, the nuclear expression of GATA binding protein 2 (GATA-2) transcription factor was significantly down-regulated by fisetin. Taken together, our study indicated fisetin has suppressive effects on IL-4 and IL-13 gene expression through the regulation of selective transcription factors.

  • Background: To increase the pharmacological effects of red ginseng (RG, the steamed root of Panax ginseng Meyer), RG products modified by heat process or fermentation have been developed. However, the antiallergic effects of RG and modified/fermented RG have not been simultaneously examined. Therefore, we examined the allergic rhinitis (AR)-inhibitory effects of water-extracted RG (wRG), 50% ethanol-extracted RG (eRG), and bifidobacteria-fermented eRG (fRG) in vivo. Methods: RBL-2H3 cells were stimulated with phorbol 12-myristate-13-acetate/A23187. Mice with AR were prepared by treatment with ovalbumin. Allergic markers IgE, tumor necrosis factor-${\alpha}$, interleukin (IL)-4, and IL-5 were assayed in the blood, bronchoalveolar lavage fluid, nasal mucosa, and colon using enzyme-linked immunosorbent assay. Mast cells, eosinophils, and Th2 cell populations were assayed using a flow cytometer. Results: RG products potently inhibited IL-4 expression in phorbol 12-myristate-13-acetate/A23187-stimulated RBL-2H3 cells. Of tested RG products, fRG most potently inhibited IL-4 expression. RG products also alleviated ovalbumin-induced AR in mice. Of these, fRG most potently reduced nasal allergy symptoms and blood IgE levels. fRG treatment also reduced IL-4 and IL-5 levels in bronchoalveolar lavage fluid, nasal mucosa, and reduced mast cells, eosinophils, and Th2 cell populations. Furthermore, treatment with fRG reduced IL-4, IL-5, and IL-13 levels in the colon and restored ovalbumin-suppressed Bacteroidetes and Actinobacteria populations and ovalbumin-induced Firmicutes population in gut microbiota. Treatment with ginsenoside Rd significantly alleviated ovalbumin-induced AR in mice. Conclusion: fRG and ginsenoside Rd may alleviate AR by suppressing IgE, IL-4, IL-5, and IL-13 expression and restoring the composition of gut microbiota.

  • The leaf of mulberry (Morus alba L) has long been used in Oriental medicine for the prevention or treatment of several diseases. However, little is known about the inhibitory effects of a single compound isolated from the mulberry leaves on inflammatory response. We are isolate a single compound of quercetin (3,3',4',5,7-pentahydroxyflavone) and astragalin (kaempferol-3-O-glucopyranoside) from the mulberry leaves, and then investigate the anti-inflammatory effects of quercetin, astragalin or quercetin plus astragalin in lipopolysaccharide (LPS)-stimulated murine peritoneal macrophages. Each compound suppressed the production of inflammatory mediators (NO, $PGE_2$ and IL-6) in LPS-stimulated murine peritoneal macrophages in a dose-dependent manner. Especially, the cotreatment of quercetin (2.5 ${\mu}M$) and astragalin (2.5 ${\mu}M$) markedly suppressed the production and the expression of inflammatory mediators. These suppressive effects were synergistically increased by their combination. These results suggest that the combination of quercetin and astragalin from the mulberry leaves may be useful for therapeutic drugs against inflammatory immune diseases, probably by suppressing the production of inflammatory mediators.

  • This study evaluated the quality characteristics of jelly prepared with different levels (0%, 5%, 10%, 15%, 20%, and 25%) of wild carrot (WC, Daucus carota L.) juice as a care food for the elderly. The lightness, redness, yellowness, and delta (${\Delta}$) values of the jelly (Control, WCJ5, WCJ10, WCJ15, WCJ20, and WCJ25) decreased with increasing amounts of wild carrot juice added. The mechanical properties, such as hardness, springiness, chewiness, and gumminess, of the jelly were decreased with increasing amounts of wild carrot juice added. The total polyphenol and total flavonoid contents of the jelly increased with increasing amounts of wild carrot juice added. The DPPH radical scavenging activity ($IC_{50}$) also increased with increasing amounts of wild carrot juice added. The ${\alpha}$-glucosidase inhibitory effects of wild carrot (WC) and WCJ25 were 71% and 54.4%, respectively, compared to the positive control (acarbose). The lipase inhibitory effects of WC and WCJ25 were 44.2% and 14.4%, respectively, compared to the positive control group (orlistat). On the other hand, the sensory evaluation score was the best at WCJ20, which contained 20% wild carrot juice. In conclusion, WCJ20 or WCJ25 is expected to be a care food for the elderly with respect to texture as well as the antioxidant and enzymatic activity (${\alpha}$-glucosidase inhibitory and lipase inhibitory activities).
