  • This study was conducted to investigate quality characteristics of white pan bread with Cudrania tricuspidata leaf powder having functional components. Mixograph, pH, TPA, volume, specific volume, moisture, CrumbScan, color value, sensory evaluation and shelf-life test were performed on the white pan bread with Cudrania tricuspidata leaf powder. The obtained results are as follows. Mixogram analysis results showed that the dough with Cudrania tricuspidata leaf powder was suitable for baking quality. The more Cudrania tricuspidata leaf powder was added in the dough, the higher dough pH was and the lower pH values after fermentation and of the final productwere. TPA analysis results showed that higher amounts of Cudrania tricuspidata leaf powder resulted in increased hardness, chewiness, and gumminess of the white pan bread. Volume and specific volume of white pan bread were decreased with increased amounts of Cudrania tricuspidata leaf powder. CrumbScan images showed that fineness of grain, crust thickness, and volume of the bread were significantly different depending on the amount of Cudrania tricuspidata leaf powder. While color value analysis showed that increasing the amount of Cudrania tricuspidata leaf powder resulted in low L and a values. The results of the acceptance test showed that CLP3 had better scores in the appearance and texture characteristics than the control, while taste and overall acceptance were higher in the CLP2 compared with the control. According to the results of the shelf-life test, the white pan bread with 1~2% of Cudrania tricuspidata leaf powder had a significantly lower hardness when compared with the control. It was judged that a lower amount of Cudrania tricuspidata leaf powder could help in maintaining the softness of bread crumbs. Moisture content in the white pan bread decreased with the increased amounts of Cudrania tricuspidata leaf powder, but there were no significant differences among specimens.

  • The present study was investigated on in vitro anti-obesity effect of 4-hydroxybenzyl alcohol from Cudrania tricuspidata. We isolated various compounds from Cudrania tricuspidata. Among these compounds, anti-obesity effects of 4-hydroxybenzyl alcohol was examined by lipase activity assay, cyclic adenosine monophosphate (cAMP)-specific phosphodiesterase type IV (PDE4) activity assay, and citrate synthase activity assay. 4-hydroxybenzyl alcohol and Cudrania tricuspidata extracts inhibited the enzymatic activities of lipase, PDE4, and citrate synthase. Lipase is known to mediate the hydrolysis of triacylglycerol in adipose tissue and cholesterol esters in other tissue or cells. Also, PDE4 hydrolyses cAMP, a crucial secondary messenger for in metabolic pathways including glucose and lipid metabolism, lipolysis, and thermogenic function. 4-hydroxybenzyl alcohol and Cudrania tricuspidata extracts induced the inhibitory effect against each enzymatic activity on several specific substrates as observed by detection at 405 or 412 nm. These findings might be attributable to the inhibition of adipogenesis, and partial prevention of obesity. In conclusion, these results show that 4-hydroxybenzyl alcohol and Cudrania tricuspidata may be a critical candidate as a natural anti-obesity source.

  • 1-Deoxynojirimycin(1-DNJ) was hardly detected by general UV detector. Therefore, in this study, we analyzed 1-DNJ, a effective functional material in which was contained the leaves of Cudrania tricuspidata and its tea by gas-chromatography. Synthesized a TMS derivative by attaching trimethylsilyl group to 1-DNJ, analyzed this by GC, and could detect a good peak. The leaves of Cudrania tricuspidata contains $1154.83{\pm}56.67$ ug/g.d.w of 1-DNJ and tea of Cudrania tricuspidata leaves does $8.01{\pm}0.61$ ug/g.d.w. This means the contents of 1-DNJ was nearly identical to each other. The larger size of the leaves had the more contents of 1-DNJ and the middle region of collection was the highest than any other collective regions of leaves.

  • 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.

  • The extract of Cudrania tricuspidata is used in ethnomedicine throughout Eastern Asia in China, Korea and Japan. In Korean traditional medicine, Cudrania tricuspidata has been used to treat eczema, mumps, tuberculosis, contusions, insomnia and acute arthritis. In addition, it has been reported that root extract of Cudrania tricuspidata has anti-platelet effects. Therefore, we investigated which compound in Cudrania tricuspidata has inhibitory effect on platelet aggregation. In this study, we tried to explain the inhibitory mechanism of steppogenin from Cudrania tricuspidata on human platelet aggregation. Collagen-induced human platelet aggregation and [Ca2+]i mobilization were dose-dependently inhibited by steppogenin and we determined the inhibition by steppogenin is due to the down regulation of extracellular-signal-regulated kinase(ERK) and inositol-1,4,5-triphosphate receptor type I(IP3RI) phosphorylation. In addition, steppogenin inhibited collagen-induced fibronectin adhesion to αIIb/β3 and thromboxane A2 generation. Thus, in the present study, steppogenin showed an inhibitory effect on human platelet aggregation, suggesting its potential use for preventing platelet-induced cardiovascular disease.

  • Male Sprageu-Dawely rats fed a cholesterol diet (Control group) or cholesterol diet supplemented with the water-soluble extract of stem bark from Cudrania tricuspidata(CTSB group) at the level of 0.5% for 2 weeks. Concentration of triglyceride in serum of CTSB group was significantly lower than that of control group. However, the other lipids concentrations of liver and serum, body weight gain, and food intake did not show significant difference between CTSB group and control group. Antioxidative activities of water-soluble extract from stem bark of Cudrania tricuspidata on the lipid peroxidation in rat were also studied in vivo by measuring the formation of thiobarbituric acid reactive substance(TBARS). Concentration of TBATS in the liver homogenates of CTSB group was significantly higher than that in control group. Nonheme iron concentration was significantly increased in the liver of CTSB group compared to control group. suggested that enhanced nonheme irom was associated with enhanced peroxidation of liver in CTSB group. These results suggested that water soluble extract from stem bark of Cudrania tricuspidata exert the hypotriglycerolemic effect and might amplify the lipid peroxidation of tissues in cholesterol fed rats.

  • In an attempt to identify the neuroprotective effect of Cudrania tricuspidata (CT) leaves against ROS (reactive oxygen species)-induced oxidative stress in neuronal cells, the extracts from CT leaves were investigated using PC12 cells and N18-RE-105 cells. The methanolic and ethanolic extracts from CT were denoted as CTM (Cudrania tricuspidata Leaves methanolic extracts) and CTE (Cudrania tricuspidata Leaves ethanolic extracts), respectively. The neuroprotective effects of the extracts were measured by DCF-DA assay, MTT reduction assay, and LDH release assay. The PC12 cells exposed to $H_2O_2$-induced oxidative stress and the N18-RE-105 cells exposed to glutamate-induced oxidative stress were treated with various concentrations of CTM and CTE. The results, CTM treatments resulted in the induction of a dose-dependent protective effect in PC12 cells and N18-RE-105 cells. Interestingly, CTE also showed neuroprotective effect in PC12 cells and N18-RE-105 cells. Therefore, these results suggest that CTM and CTE could be a new potential candidate as neuroprotective agents against ROS-induced oxidative stress in neuronal cells.
