We conducted this study to investigate the effect of methanol extract from Mulberry Fruit on the lipid metabolism and liver function in cholesterol-induced hyperlipidemia rats. We used 5 Mulberry Fruit varieties, including Daeryukppong, Kuksang 20, Subongppong, Wild variety and Cataneo. The yield of methanol extract from freezing dried Mulberry Fruits was 43.5-64.6%. Animal treated with Wild variety from Mulberry Fruit showed the decrease in body weight, food efficiency ratios, serum triglyceride (85%), and GOT value (86%). Our results suggest the hypolipidemic action of Wild variety from Mulberry Fruit.

This study was presented to the physiological activities such as metal chelating capacity, superoxide dismutase-like activity, anti-inflammation, cytotoxicity from Zanthoxylum schnifolium fruit. The values for metal chelating capacity of 1 mg/mL of 70% EtOH and 70% MeOH extracts were 68% and 67%, respectively, it was shown that metal chelating capacity in a dose-dependent manner. The 100% EtOH and 100% MeOH extract exhibited strong superoxide dismutase-like activity. The highest SOD-like activity obtained from 100% EtOH was 51% at a concentration of 4 mg/mL. The all extracts of Zanthoxylum schnifolium fruit except $H_2O$ extract significantly decreased the concentration of LPS-induced NO in Raw 264.7 cells. The 100% EtOH, 100% MeOH and 70% EtOH extract represented the highest activity in the anti-inflammation properties in vitro. However, the 100% EtOH and 100% MeOH extracts has cytotoxicity in Raw 264.7 cells and it may affect cell viability. Conclude that 70% EtOH extract was most suitable for anti-inflammation. Our results revealed that the Zanthoxylum schnifolium fruit expected to physiological activities.

In a previous study, a mulberry fruit extract(MFE) supplement exhibited anti-inflammatory activity and improved serum lipid profiles in arthritic rats. The objective of this study was to determine whether dietary MFE could ameliorate inflammatory parameters and serum lipid levels in humans. Twenty-six middle-aged subjects(mean body mass index=27 $kg/m^2$) consumed MFE(100 $m{\ell}/day)$ after lunch for 4 wks. Anthropometric measurements, serum oxidative stress markers and serum lipid profile analyses were performed at baseline and then at 4 wk following the study. There were no significant differences in anthropometric measurements, including BMI, WHR, and body fat composition. After the 4 wk-intervention, serum levels of C-reactive protein(CRP), ferric-reducing ability of plasma(FRAP), serum triglyceride(TG) and LDL-cholesterol had significantly decreased(p<0.05), whereas serum levels of HDL-cholesterol significantly(p<0.05) increased. These findings suggest the consumption of mulberry extract may be protective against inflammation and the atherosclerotic state in elderly obese men at high risk for cardiovascular disease(CVD).

Longan (Dimocarpus longan Lour.) has been used as a traditional oriental medicine and possesses a number of physiological activities. In this study, we used cell-based herbal extract screening to identify longan fruit extract (LFE) as an activator of osteoblast differentiation. LFE up-regulated alkaline phosphatase (ALP) activity, induced mineralization, and activated Runx2 gene expression in MC3T3-E1 cells. Furthermore, treatment of MC3T3-E1 cells with LFE promoted the phosphorylation of extracellular signal-regulated kinase1/2 (Erk1/2); however, abrogation of Erk1/2 activation with PD98059 resulted in down-regulation of the phospho-SMAD1/5/8 and Runx2 levels, which in turn reduced the ALP activity. Our findings suggest that LFE exerts its osteogenic activity through activation of the ERK signaling pathway and may have potential as an herbal therapeutic or a preventive agent for the treatment of osteoporosis.

The present study was aimed to examine the role of endothelium in the relaxant effect of hawthorn fruit extract of Crataegus pinnatifida in four different types of rat arteries, posterior cerebral communicating artery, right descending coronary artery, common carotid artery, and aorta. In $9,11-dideoxy-11{\alpha}$, $9{\alpha}-epoxy-methanoprostaglandin$ $F_{2{\alpha}}$ (U46619)-preconstricted arterial rings except for aorta, the extract produced endothelium-independent relaxations with similar potency. This relaxation was unaffected by pretreatment with $100\;{\mu}M\;N^G-nitro-L-arginine$ methylester (L-NAME, the nitric oxide synthase inhibitor), $3\;{\mu}M$ 1H-[l,2,4]oxadiazolo$[4,2-{\alpha}]$quinoxalin-1-one (ODQ, the guanylate cyclase inhibitor), or $10\;{\mu}M$ indomethacin (the cyclooxygenase inhibitor). Putative $K^+$ channel blockers (charybdotoxin plus apamin or glibenclamide) did not affect the extract-induced relaxation in cerebral or coronary artery rings. In contrast, in rat aortic rings the extract produced significantly smaller relaxant response in endothelium-denuded rings than that in endothelium-intact rings. Pretreatment with L-NAME or ODQ abolished the extractinduced endothelium-dependent aortic relaxation, whilst indomethacin $(3\;{\mu}M)$ had no effect. The present results indicate that hawthorn fruit extract possesses a vasorelaxing effect in cerebral, coronary and carotid arteries and this effect is independent of the presence of a functional endothelium. However, the extract-induced endothelium-dependent relaxation in rat aorta was mediated through endothelial nitric oxide and cyclic GMP-dependent mechanisms, suggesting that active components in the extract may act on endothelium to stimulate release of nitric oxide in large conduit arteries of the rats.

The effects of incorporating hot water extract of Schisandra chinensis fruit on the physicochemical and sensory properties of Sikhe were investigated. The extract was incorporated at 5 levels (0, 10, 20, 30, 40, and 50%, v/v) by replacing equivalent amount of distilled water. The pH decreased while the soluble solids content increased significantly with the increase in the extract replacement (p<0.05). Redness ($a^*$-value) increased significantly as the extract concentration increased (p<0.05); on the other hand, lightness ($L^*$-value) and yellowness ($b^*$-value) did not show any direct relationships with the extract replacement. Color, sour taste, and sweet taste except for Sikhe flavor were distinctively classified by the sensory analyses (p<0.05). Correlation analysis indicated that level of extract incorporation was well-correlated with all the physicochemical and sensory properties studied except for $L^*$- and $a^*-$ value. Finally, the consumer test based on Friedman-type statistic, suggested that 10% incorporation of the hot water extract of Omija fruit was recommended for making Sikhe.

To investigate the antihyperglycemic and antihyperlipemic effect of 80% ethanol extract of Schizandra Chinensis fruit, we induced diabetes in the rats with streptozotocin (STZ) and administered schizandra extract or Acarbose to diabetic rats for 21 days by oral administration. Consequently, the groups treated using schizandra extract decreased blood glucose levels more 39% than no treatment group and the case of Acarbose group was decreased it about 21%. The concentration of cholesterol, triglyceride and LDL-C in blood was also decreased while treating schizandra extract, on the other hand, HDL-C concentration was significantly increased it about 26%. Those results induced that anti-atherogenic index (AAI) in blood was improved more than 82% level like normal condition, especially in treatment of schizandra extract 100 mg. The lipid profiled in feces was likewise showed apparent tendency to decrease and food efficiency ratio of diabetic rats was became higher for treatment with schizandra extract, but Acarbose group had low efficiency in compared with the result of glucose level and lipid profile in blood. As a result, schizandra extract is regard a good medicine for diabetes due to improve physical constitution, blood glucose and lipid level caused hyperglycemia and suggest that schizandra extract has real effects on the diabetes complication as atherosclerosis, coronary heart disease, high blood pressure.

This study aimed to examine the effect of the Schizandra chinensis fruit and Morus alba leaf on insulin expression in HIT-T15 cells, which is exposed by glucose. The total polyphenol contents of the S. chinensis fruit ethanol extract and the M. alba leaf hot-water extract were $20.11{\pm}0.35$ mg/g and $50.02{\pm}0.62$ mg/mL, respectively. The S. chinensis fruit ethanol extract and the M. alba leaf hot-water extract contained $2.85{\pm}0.15$ and $8.76{\pm}0.43$ mg/g flavonoids, respectively. The antioxidant ability of the M. alba leaf hot-water extract was found to be superior to that of the S. chinensis fruit ethanol extract. Compared to the HIT-T15-treated 10 mM 2-deoxy-D-glucose, the $100{\mu}g/mL$ S. chinensis ethanol extract was found to have a two fold increase in insulin productivity. Moreover, the $100{\mu}g/mL$ M. alba leaf hot-water extract promoted the insulin secretion of high-glucose-damaged HIT-T15 almost ten fold. The above results showed that the S. chinensis fruit ethanol extract and M. alba leaf hot-water extract may improve the insulin productivity of the beta cell with glucose-induced oxidative damage. These data suggest that the S. chinensis fruit ethanol extract and the M. alba leaf hot-water extract can be used as food materials for the regulation of insulin secretion.

In this study, 8 kinds of fruits and vegetables such as apples, pears and radishes were cut and hot water extracts and Steamed hot water extract from fruits and vegetables were prepared and used as experimental substrates. As a result of fermenting with 1% (W/V) red ginseng extract (W/V) and 8 types of lactic acid bacteria mixed starter added to the lactic acid bacteria fermented extract, the pattern and content of ginsenosides were almost unchanged in the fruit and vegetable extract group and the steam treatment group. However, in the lactic acid bacteria fermented group, the TLC pattern was changed according to the fermentation process and treatment, and the content of ginsenosides converted into Rg₃(S) and Rg₅ increased. No change in the number of lactic acid bacteria (cfu) was observed in all four types of fruit and vegetable extracts. The number of lactic acid bacteria CFU was slightly decreased in the four fermented groups of fruit and vegetable extracts, but the growth inhibitory effect of beneficial bacteria was not significant. The growth inhibitory effect of the three harmful bacteria was not affected by the growth of E. coli and Pseudomonas in the four fruit and vegetable extracts. However, the proliferation of Salmonella was inhibited, which was confirmed as the growth inhibitory effect of the fruit and vegetable extract regardless of whether the steamed hot water extract or red ginseng extract was added.

Nutritional composition and antioxidative capacity of mulberry fruit (Ficus-4x) were investigated for evaluation as new red-colored fruit. Contents of moisture, crude fat, crude protein, and vitamin C were similar, whereas that of crude ash was higher, to those of other berry fruits. Contents of minerals (Ca, 14.33 mg/100 g; P, 39.98 mg/100 g; Fe, 6.01 mg/100 g; Zn, 4.04 mg/100 g; Mn, 2.26 mg/100 g), particularly Fe, were higher than those of other berry fruits. Hardness, springness, cohesiveness, gumminess, and chewiness of mulberry fruit were higher, and color values (L, 36.03; a, 1.80; b, 1.54) were lower than those of strawberry. Relative scavenging activities of mulberry fruit methanol extract and its cyanidine 3-glucoside on 1, 1-diphenyl-2-picrylhydrazy radical (DPPH) were 35.7 and 78.2%, respectively, using butylated hydroxyanisole (BHA) as standard. Antioxidant activities in corn oil (peroxide values and conjugated dienoic acid) were tertiary butylhydroquinone (TBHQ) > mulberry fruit ethanol extract > mulberry fruit water extract > butylated hydroxytoluene (BHT) > tocopherol. Results show mulberry fruit can be very useful red-colored fruit for development of functional foods with beneficial effects on radical scavenging and antioxidative capacities.
