Objectives : This study aims to investigate the acute oral toxicity and safety of Samsoeum (Shensuyin) extracts and fermented Samsoeum extracts. Methods : For that objective, we used ICR mice. ICR mice were administerd orally with dosage of 1250mg/kg, 2500mg/kg and 5000mg/kg of Samsoeum extracts and fermented Samsoeum extracts. Results : We daily examined number of deaths, clinical signs, body weights and gross findings for 2 weeks. 1. The results of acute oral toxicity using ICR mice showed that LD50 of value over 5000 mg/kg. 2. Samsoeum extracts and fermented Samsoeum extracts not affect on bodyweight gross findings of ICR mice. 3. The results of Serum chemistry analysis and Complete Blood Count(CBC) through the autopsy were showed normal range values. Conclusions : Samsoeum extracts and fermented Samsoeum extracts did not show any toxic effects in ICR mice. And oral LD50 value was over 5000mg/kg in ICR mice and it is very safe for ICR mice.

Objectives : This study was carried out to investigate the acute toxicity and safety of Palmultang and Fermented Palmultang Extract in Mice. Methods : To evaluate their acute toxicity and safety, 0 (control group), 2000 mg/kg of Palmultang and Fermented Palmultang Extracts were orally administered to 15 male and 15 female ICR mice. After a single administration, we observed survival rates, behavioral pattern, clinical sign, body weight. The results of biochemical analysis and hematological analysis were no any significant change. Results : Compared with the control group, we could not find any toxic alteration in all treated mice. Conclusions : Overall, the results suggest that, the oral administration of Palmultang and Fermented Palmultang extracts did not produce significant toxic effect in mice.

This study was conducted to analyze the antioxidant activities of fermented black jujube and to compare these with those of dried jujube, for the development of functional materials. The antioxidative activities of dried jujube and fermented black jujube extracts were analyzed by electron-donating ability (EDA) using 1,1-diphenyl-2-picryl hydrazyl (DPPH), superoxide-dismutase-(SOD)-like activity by pyrogallol, nitrite-scavenging ability, and xanthin oxidase. The yield of the fermented black jujube extracts was higher than that of the dried jujube extracts, and that of the ethanol extracts was higher than that of the hot-water extracts. The total phenol contents of the hot-water extracts from fermented black jujube were higher. The EDA values of the hot-water and ethanol extracts from fermented black jujube and dried jujube increased with an increase in extract concentration, and were about 85% in a $1000{\mu}g/mL$ extract concentration. The SOD-like activity increased with an increase in extract concentration. The SOD-like activity of the hot-water extract from fermented black jujube was higher than that of the other extracts. The nitrite-scavenging ability at pH 1.2 of the hot-water extracts from dried jujube was higher than that of the other extracts. The xanthine oxidase inhibitory activities of the hot-water and ethanol extracts from fermented black jujube were higher than those of the other extracts, and increased along with the concentrations of the extracts.

Citrus, yield of which is the highest among fruits produced in Korea, is extensively consumed for processed food items. The amount of by-products of citrus produced from the processing within a short period after the harvest is tremendous. These by-products are mostly dumped into land or neglected because of cost involved in processing them. The aim of the present study was to explore the usefulness of the by-products as a new material by examining the anti-inflammatory activity of fermented extracts of citrus peels. The peels of 'unshu' (Citrus unshiu) was fermented with Aspergillus niger and their extracts before or after fermentation were analyzed using HPLC. The analysis showed that neohesperidin level considerably increased and the two new compounds were synthesized after fermentation. The anti-inflammatory activity of the fermented extracts was examined on RAW 264.7 murine macrophage cells stimulated with lipopolysaccharide. Fermented unshu extracts significantly enhanced the decrease of nitric oxide (NO) production, iNOS and COX-2 expression, comparing with those of unfermented extracts. Also TNF-${\alpha}$ and IL-6 production, both of which are pro-inflammatory cytokine, were more inhibited in fermented extracts. These results showed that the fermentation and promotion of the function of the by-products of citrus peels will help find a new application.

This study was carried out to investigate the acute toxicity and safety of Ssanghwa-tang extract fermented with Ganoderma lucidum. To evaluate the acute toxity and safety, 0(control group), 1250, 2500 and 5000 mg/kg of Ssanghwa-tang and fermented Ssanghwa-tang extracts were orally administered to 20 male and 20 female ICR mice. After single administration, we observed survival rates, general toxicity, changes of body weight, and autopsy. Compared with the control group, we could not find any toxic alteration in all treated groups (1250, 2500 and 5000 mg/kg). $LD_{50}$ of Ssanghwa-tang and fermented Ssanghwa-tang extracts might be over 5000 mg/kg and it is very safe to ICR mice.

Beet (Beta vulgaris) is a crop similar to sugar beet, chard and leaf beets, and its origin is the Mediterranean coast of southern Europe and Central Asia. Among the components contained in beet, betalain, the main component of the root, has been reported to prevent lipid peroxidation induced by active oxygen and free radicals due to its high radical scavenging ability. Among these, the betalain, betanin (Betanidin 5-O-${\beta}$-glucoside) contains both phenolic and cyclic amine groups, all of which are highly electron-donating and act as antioxidants and has tyrosinase inhibitory activity. Betanin accounts for about 75-95% of the total pigment found in the beet. EM stands for effective microorganisms and is a collection of beneficial microorganisms. EM includes yeast, lactic acid bacteria, mycelia, photosynthetic bacteria, actinomycetes, etc. Human patch test according to CTFA guidelines was observed to be a safe source of no stimulation when 5% (v/v) of the EM fermentation liquid was applied to the human body. In addition, beneficial microorganisms are synergistic in the process of co-existence and cultivation and it has the effect of increasing antioxidant capacity and inhibiting corruption. This study confirms the difference in tyrosinase inhibitory activity and betanin content of beetroot extracts and EM fermented beetroot extracts. Hence, these results confirm that EM fermented beetroot extracts are highly beneficial for the human body.

The purpose of this study was investigation of quantitative analysis of marker substances in Paeonia lactiflora extracts by solid fermentation. High performance liquid chromatography (HPLC) for the determination of albiflorin and paeoniflorin in P. lactiflora extracts by solid fermentation, the separation method was performed on C18 column ($250\;mm\;{\times}\;4.6\;mm$, $5\;{\mu}m$, RS tech) using gradient solvent mixtures of water-acetonitrile with photodiode array detector (230nm). The flow rate was 1.0 ml/min. Retention time of albiflorin and paeoniflorin was about 28.88, 31.92 min and linearity of calibration was showed good result(r2 = 0.9998, 0.9996), respectively. Content of albiflorin was $0.090\;{\pm}\;0.03%$ in P. lactiflora extract(control), $0.102\;{\pm}\;0.00%$ in P. lactiflora extract fermented with Paecilomyces japonica, $0.056\;{\pm}\;0.01%$ in P. lactiflora extract fermented with Ganoderma lucidum, $0.093\;{\pm}\;0.00%$ in P. lactiflora extract fermented with honey and $0.046\;{\pm}\;0.00%$ in P. lactiflora extract fermented with Nuruk. Content of paeoniflorin was $4.506\;{\pm}\;0.13%$ in control, $2.599\;{\pm}\;0.04%$ in P. lactiflora extract fermented with Paecilomyces japonica, $1.222\;{\pm}\;0.03%$ in P. lactiflora extract fermented with Ganoderma lucidum, $2.750\;{\pm}\;0.05%$ in P. lactiflora extract fermented with honey and $0.847\;{\pm}\;0.00%$ in P. lactiflora extract fermented with Nuruk, respectively.
