  • Objectives : Cudrania tricuspidata (C. tricuspidata) is well-known traditional herbal remedy and its root, leaf and fruit were used for treatment of inflammation, tumor and painkilling. However, effect of C. tricuspidata fruit on tight junction is still unknown. The aim of this research was to determine the effect of C. tricuspidata fruit extract on human keratinocyte HaCaT cells. Methods : The antioxidant effects of water extract of C. tricuspidata (WECT) and ethanol extract of C. tricuspidata (EECT) were analyzed by using an ABTS assay. To confirm the cytotoxicity of WECT and EECT, MTS assay was performed. The mRNA expression levels of tight junction related genes were analyzed using quantitative RT-PCR analysis. Furthermore, dispase assay was used to investigate the alteration of cell-cell adhesion strength of EECT treated HaCaT cells. Results : WECT and EECT showed strong antioxidant activity. No obvious cytotoxicity was observed in both WECT and EECT until $2.0mg/m{\ell}$ concentration. The mRNA expression level of Claudin 6 were significantly increased by EECT treatment, whereas the WECT did not affect the expression of Claudin 6. Furthermore, EECT treatment enhances cell-cell adhesion strength. Conclusions : In this study, we investigated the physiological activities of the extracts of Cudrania tricuspidata fruit extracts on human keratinocytes by two different extraction methods. EECT might have an anti-aging activity on the skin by reducing oxidative stress. Moreover, it may be a useful ingredient in atopic dermatitis and skin-moisturizing, given its effects of altering Claudin 6 gene expression and enhancing cell-cell adhesion strength.

  • Polyphenolic compounds widely occurring in the traditional medicine plants have been reported to possess strong antioxidant activity. The antioxidative substances of water soluble extract from leaves, stem bark, root bark and fruit powder of Cudrania tricuspidata were tested in three different in vitro experimental models. In oxidation models using DPPH( , ' diphenyl picrylhydrazyl) method, Fe2+ induced linoleic acid peroxidation, and autooxidation of hepatic microsomal membranes, the antioxidative activities of water soluble extract from stem bark were strong than that from leaves and root bark. Fruits of Cudrania tricuspidata contained the highest amounts of polyphenolic compounds among the parts of this plant. The changes in polyphenolic compound contents of fruit powder caused by heat treatment (20oC, 40oC, and 60oC) were also monitored. After water blanching, contents of phenolic compounds was increased slightly in the following order; 20oC(1454mg), 40oC(1487mg), and 60oC(1511mg). These results supports that water soluble extracts from Cudrania tricuspidata contain antioxidative compounds.

  • Water extracts of root, leaf, branch and fruit of Cudrania tricuspidata were tested to use as natural antiwrinkle and whitening cosmetic ingredient. Root extract indicated 86.5 mg/g polyphenol concentration and 55.5 mg/g flavonoid concentration. From MTT test, root, branch and fruit extract did not show cell toxicity up to $1,000{\mu}g/mL$, however, leaf extract displayed significant cell toxicity in concentrations higher than $200{\mu}g/mL$. Cudrania tricuspidata root extracts displayed excellent 81% tyrosinase inhibition (whitening effect), 58% elastase inhibition (antiwrinkle effect) at $500{\mu}g/mL$ and showed minor UVB absorbance. When solution and lotion formulation were made including Cudrania tricuspidata root extract, they are stable at $25^{\circ}C$ for 21 days, but showed significant deviation in viscosity and particle size at $47^{\circ}C$. From the study, Cudrania tricuspidata root extract demonstrated good potential for natural whitening and antiwrinkle cosmetic agent.

  • Polysaccharides produced in microorganisms and plants are known to increase the immune response in the body. We proposed analysis of beta-glucan contents of phellinus linteus fruit body (FB) and mycelium (MC) cultured in cudrania tricuspidata. Also, we examined whether fruit body and mycelium can increase the immune response in cyclophosphamide-induced immunosuppression animal models. We injected cyclophosphamide (50 mg/kg) twice to produce immunosuppression mice. Then, FB (200 mg/kg) and MC (200 mg/kg) were oral administered for 14 days. In order to confirm the immune-enhancing effect of FB and MC, we analyzed spleen weight, the number of immune cells, cytokines, and immunoglobulins levels. Cyclophosphamide decreased the weight of spleen, the number of immune cells. However, FB and MC have significantly increased the weight of spleen, the number of white blood cell, lymphocyte and monocyte. In addition, they have significantly increased immune-related cytokines (IL-2 and IFN-${\gamma}$) and immunoglobulins (IgA, IgG, IgM) levels. As a results, phellinus linteus fruit body (FB) and mycelium (MC) cultured in cudrania tricuspidata can be used as effective natural materials for immune-enhancing.

  • To raise the added value of the fruits of Cudrania tricuspidata, Cudrania tricuspidata vinegar was produced and examined for its fermentation conditions. Forty nine acetic acid bacteria with resistance against acetic acid, ethanol, and sulfide as high acetic acid producers were isolated from fermented foods and identified as Acetobacter indonesiensis, A. cerevisiae, A. orientalis, A. tropicalis, A. fabarum, A. pasteurianus, and A. syzygii based on the results of the analysis of the 16S rRNA gene sequences. Among them, two GRAS strains, A. pasteurianus SCMA5 and SCMA6, were finally selected for the production of acetic acid. Optimal vinegar productions were obtained from the medium containing 40% (v/v) fruit juice of Cudrania tricuspidata and 5% (v/v) ethanol at $25^{\circ}C$ for 72 hr. The sensory panel preferred the vinegar fermented with the SCMA06 to that with the SCM05 strain. The radical scavenger capacity of DPPH was 53% higher than that of the control in the vinegar fermented with the SCMA06 strain. The ${\alpha}$-glucosidase inhibitor activity as an index of the antidiabetic drug showed 91% inhibition, which is higher than that of acabose. This study will be helpful for the scale-up production of vinegar with the fruit of Cudrania tricuspidata.

  • We investigated a physiological function by fermenting a medicinal mushroom, (Cudrania tricuspidata fruit). A fermentation using lactic acid bacteria and the extracts isolated from 70% ethanol fractionation was included in cultured mouse spleen cells for cytokine secretion. As a result, total polyphenol content improved by 47% by organic acid fermentation. This was regarded as immune activity in fermented C. tricuspidata fruits, as the levels of interleukin (IL)-2 and IL-4 secretion increased. In addition, when the extracts were treated with a stimulant lipopolysaccharide, the secretion of helper T (Th) 1 cytokines IL-2, IL-12, and tumor necrosis factor-${\alpha}$ was suppressed, while the secretion of Th2 cytokines IL-4, IL-5, IL-6, and IL-10 significantly increased. Therefore, this study suggests that fermentative C. tricuspidata fruit extracts can contribute to the suppression of cellular immune reactions induced by the expression of Th1 cells and activation of the expression of Th2 cells inducing humoral immune reactions associated with the antibody generation by B lymphocytes.

  • The objective of this study was to assess antioxidant activities of leaves and fruit powder of Cudrania tricuspidata (CT) with different particle sizes (crude, 500 ㎛, 150 ㎛), and determine the physicochemical properties and microbial counts of pork patties with various levels of CT fruit powder (CTFP) during refrigerated storage. Total phenolic content of crude leaves had the highest value of 3.54 g/100 g (p<0.05). Overall, CT leaves (CTLP) had higher total phenolic content than CTFP (p<0.05). 1,1-Diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity of CTFP was higher than that of CTLP (p<0.05), which showed higher iron chelating ability and reducing power than CTFP (p<0.05). After pork patties were manufactured with 0.5% and 1.0% of CTFP at 500 ㎛, pH, color values, thiobarbituric acid reactive substance (TBARS), and peroxide values (POV) were then measured. The addition of CTFP into pork patties significantly (p<0.05) increased redness and yellowness values of patties. TBARS values of pork patties containing CTFP were lower (p<0.05) than those of CTFP-0 patties after 10 days of storage. Pork patties added with CTFP showed no significant (p>0.05) difference TBARS values among different storage periods. POV values of pork patties containing CTFP were lower than those of the control from 3 days up to the end of refrigerated storage (p<0.05). These results suggest that CTFP could be used as a natural antioxidant to retard lipid oxidation in meat products during refrigerated storage.

  • Cudrania tricuspidata (C. tricuspidata) is a deciduous tree found in Japan, China and Korea. The root, stems, bark and fruit of C. tricuspidata has been used as traditional herbal remedies such as eczema, mumps, acute arthritis and tuberculosis. In this study, we investigated the potential efficacies of this natural compound by focusing on the inhibitory effect of cudraxanthone L (CXL) isolated from the roots of C. tricuspidata on human platelet aggregation. Our study focused on the action of CXL on collagen-stimulated human platelet aggregation, inhibition of platelet signaling molecules such as fibrinogen binding, intracellular calcium mobilization, fibronectin adhesion, dense granule secretion, and thromboxane A2 secretion. In addition, we investigated the inhibitory effect of CXL on thrombin-induced clot retraction. Our results showed that CXL inhibited collagen-induced human platelet aggregation, intracellular calcium mobilization, fibrinogen binding, fibronectin adhesion and clot retraction without cytotoxicity. Therefore, we confirmed that CXL has inhibitory effects on human platelet activities and has potential value as a natural substance for preventing thrombosis.
