  • Objectives : Samchulgeonbi-tang (shenzhujianpi-tang) has been prescribed as one of traditional herbal medicine for treatment of stomach diseases since ancient time in Korea. Samchulgeonbi-tang extract was fermented by Lactobacillus spp. for improving the effect. However, the toxicity and safety of fermented Samchulgeonbi-tang (FS) extract were not confirmed. Therefore, this study was performed to evaluate the acute toxicity and safety of FS extract. Methods : To evaluate the acute toxicity and safety of FS extract, several doses of FS extract, 0, 500, 1000 and 2000 mg/kg, were orally administered to 20 male and 20 female ICR mice, respectively. After treatment with FS extract, we observed mortality, general toxicity, behavior and change of body weight for the 14 days. After 14 days of oral administration, all mice were sacrificed and hematological parameters were analyzed from blood serum. Results : In present study, the toxic signs such as mortality or abnormal behaviors by FS extract were not observed. There are no significant differences between FS-treated group and control group in body weight, organ weights, and hematological parameters. Conclusions : The remarkable adverse effects by FS extract were not observed in ICR mice. Also, any death was not occurred at all treated FS doses, 500, 1000 and 2000 mg/kg. Therefore, the approximate lethal dose (ALD) of FS extract may be more than 2000 mg/kg.

  • This study was conducted to investigate the effects of fermented capsicum and a capsicum product on lipid metabolism. Fermented capsicum was prepared from red pepper puree tov three months. After 9() days of fermentation, capsaicin and dihydrocapsaicin concentrations were reduced from 24.7 and 14.7 g/mL to 15.5 and 6.45 g/mL, respectively. The capsicum product was prepared from the fermented capsicum mixed with prune extract, green tea extract, neroli extract and oligo-saccharide. Thirty-two male Sprague-Dawley rats were as- signed to four dietary groups (control, high-fat control (BE-control), high-fat-fermented capsicum (HF-S-1), high- fat-capsicum product (HF-S-2)). Plasma and hepatic lipid profiles were examined after three weeks of experimental diet. Food intakes were significantly lower in the HF-S-1 and HF-S-2 groups compared to the control group (p<0.05). The weight of perirenal fat pads was lowest in animals on the control diet (low-fat) and highest in high-fat control diet. The addition of fermented capsicum to high fat diets, HF-S-1 and HE-S-2 groups, resulted in significantly lower fat pad weights compared with the HF-control group. Both fermented capsicum (HF-S-1) and the capsicum product (HF-S-2) groups had lower plasma TG levels, atherogenic-index, and liver TG levels than the BE-control group (p <0.05). Liver TC levels were significantly lower in the HF-S-2 group than the HF-control group. The results demonstrate a hypolipidemic effect of fermented capsicum and the fermented cap-sicum product.

  • The purpose of this study was to evaluate the improved antioxidant activity of Aronia extract fermented by lactic acid bacteria isolated from fermented seafoods. Aronia fruits were collected from Sunchang, Chonbuk, South Korea. And these collected fruits were lyophilized for fermentation. For the selection of effective lactic acid bacteria useful for fermentation. Aronia fermented by lactic acid bacteria that isolated from fermented seafood was extracted with 60% ethanol. Antioxidant activity of Aronia extract was evaluated on the DPPH radical scavenging activity and total polyphenol contents were studied. To determine the optimal fermentation conditions, the changes of antioxidant efficacy was evaluated by controlling temperature (25, 30, 37, $40^{\circ}C$), Time (0~5 day) and inoculation dose of lactic acid bacteria (0.125~0.5ml). To confirm the antioxidative effect of Aronia fermented under optimal conditions, the DPPH & ABTS radical scavenging activity, total polyphenol & flavonoid contents were compared before and after fermentation were studied. 16 different kinds of lactic acid bacteria were isolated from fermented seafood, and of which antioxidant activity of Aronia fermented by Pediococcus pentosaceus B1 was maximum. Aronia fermentation at $37^{\circ}C$ was maximized when fermented for 3 days and fermentation time is decreased as the start inoculation amount of lactic acid bacteria increased. The degree of increase in antioxidant activity after Aronia fermentation is that DPPH & ABTS radical scavenging activity was increased about 27%, 20% and total polyphenols & flavonoids contents was increased about 12%, 15%. In the result of this experiment indicated that fermentation process enhances the antioxidant efficacy of Aronia.

  • The present study was performed to compare the antioxidative and whitening activities of fermented soybean extract (FSB) and non-fermented soybean extract (SB). Antioxidative and whitening activities of FSB and SB were evaluated by the determination of DPPH, superoxide radical and hydroxyl radical scavenging activities, linoleic acid inhibition activity, and tyrosinase inhibition activity. FSB showed the higher effect than SB in the antioxidative activities. Also FSB showed the better effect than SB in whitening activity. These results demonstrated that the fermentation played a more excellent role than the non-fermentation in antioxidation and whitening. Therefore, this study suggested that FSB could be a useful cosmetic ingredient for antioxidation and skin whitening.

  • This study was to elucidate the anti-inflammatory activities of a methanol extract derived from the fermented bark of Dioscoreae batatas on LPS-induced activation in macrophages. It was fermented with Lactobacillus fermentum and L. plantarum and then analyzed to identify the contents of methanol extract and diosgenin. The fermented product showed 3-fold increase in the extraction yield by methanol, and 1.8-fold increase in diosgenin contents, compared to that from the dried bark of D. batatas. Although the methanol extract from the unfermented D. batatas inhibited lipopolysaccharide (LPS)-induced production of nitric oxide (NO) and TNF-${\alpha}$ in J774 A.1 cells, the methanol extract from the fermented product revealed significantly the enhanced the inhibitory activities on LPS-induced production of NO and TNF-${\alpha}$. Taken together, our results indicate that fermentation of bark of D. batatas elevates the functional activity inhibiting macrophage activation through the increase of the content of anti-inflammatory compounds. Thus, its methanol extract may be useful as a functional material for the therapy of inflammatory diseases.

  • The current study examined the impact of fermented barley sprout extract prepared using lactic acid bacteria (Lactobacillus sp.) in decreasing odor and increasing livestock productivity and measured the difference in the polyphenol and flavonoid contents of the extract after fermentation. Furthermore, the effectiveness of fermented barley sprout extract was evaluated through order level and production index of livestock by supplying it to a broiler house. The results showed that with fermented barley sprout extract, the polyphenol and flavonoid contents were increased significantly by 174% and 562%, respectively. When the extract was applied as an additive to drinking water in the test farm, the productivity improved by about 10%, the mortality rate was reduced by about 66%, and there was a significant decrease in odor by about 80%. Compared with the control group, the production index increased by about 21%, the feed requirement decreased by about 8%, the odor showed a decrease in the NH3 level, and no other gas was detected. It was observed that lactic acid bacteria settle in the intestine, suppress the proliferation of bacteria that cause diarrhea and enteritis, and help digestion. The lactic acid bacteria effectively remove bad odor gases such as NH3, Amines, H2S and CH4S. Such odor reduction improves productivity. Our findings provide valuable information for quality water supply, production optimization and livestock management.

  • For prevention of moisture adsorption, the fermented red ginseng extract spherical granules were coated by using hydrophobic fractions. The hydrophobic parts were extracted from red ginseng such as the perfect soluble part in 90% ethanol (PSE) and non-soluble part in hot water (NSHW). The optimum operating conditions for making fermented red ginseng extract spherical granules coated with PSE were a feeding rate (FR) of 0.49 mL/min, atomization air pressure (AP) of 2.14 bar, and product temperature (PT) of $48.96^{\circ}C$., whereas conditions for granules coated with NSHW were a FR of 0.61 mL/min, AP of 2.75 bar, and PT of $46.30^{\circ}C$. The solubility of coated fermented red ginseng extract spherical granule was lower than that of not coated. The fermented red ginseng extract spherical granules coated with NSHW showed more preventative effects for moisture adsorption than those coated with PSE, although there were no differences in solubility and fluidity. In the sensory evaluation, granules coated with hydrophobic fractions extracted from red ginseng were shown to be bitterer and less soluble than those not coated spherical granules. In conclusion, fermented red ginseng extract spherical granules coated with hydrophobic extracts from red ginseng showed a preventative effect against moisture.

  • This study was undertaken to determine the effect of fermented soybean extract and its fractions on skin cell proliferation and growth. The extract was procured by the pepsin and Lactobacillus rhamnosus fermentation of soybean. LC-MS analysis was performed subsequent to soybean fermentation, and cell viability was measured by the WST-1 assay. Cell proliferation was observed to increase after exposing cells to the fermented soybean extract and its fractions at all concentrations tested (0~2,000 ㎍/mL). In particular, compared to the normal control group and 120 % proliferation of the EGF (epidermal growth factor) positive control group, 160~180 % cell proliferation was achieved at 800 ㎍/ml, indicating the excellent potential as an application material for skin aging inhibition and skin cell regeneration. In addition, we also examined the effects of fermented soybean extract and its fractions on wound healing ability, in HaCaT cells and fibroblasts. Our results indicate excellent cell migration abilities after treatment with fermented soybean extract and its fractions, as compared to the control treatment. Similar cell migration abilities were observed in the positive control group (EGF). Taken together, our results indicate that fermented soybean extract and its fractions (F4 and F5) exert amelioratory effects as a natural material for skin.
