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.

본 연구는 건대추와 건대추를 이용하여 온도 $50^{\circ}C$, 습도 90%의 항온항습기에서 숙성시켜서 제조한 발효 흑대추의 열수 및 에탄올 추출물에 항산화성을 평가함으로서 대추의 식품학적인 기능성을 검토하고자 하였다. 건대추와 발효 흑대추의 열수 및 70% 에탄올 추출물의 수율은 발효 흑대추 추출물에서 높았으며, 70% 에탄올 추출물이 열수 추출물에 비해 높았다. 총 폴리페놀 함량은 흑대추 추출물에서 높게 나타났으며, 열수 추출물이 70% 에탄올 추출물보다 높은 함량을 보였다. 전자공여능은 건대추와 발효 흑대추의 추출물의 열수 및 에탄올 $1,000{\mu}g/mL$의 농도에서 각각 85.0% 이상의 전자공여능을 보였고, SOD 유사활성능은 발효 흑대추 추출물이 건대추 추출물에 비해 높았으며, 대체적으로 열수 추출물에서 높게 나타났다. pH 1.2에서의 아질산염 소거능은 에탄올 추출물에 비해 열수 추출물에서 높았으며, 발효 흑대추보다 건대추 추출물에서 높게 나타났다. Xanthine oxidase 저해활성은 건대추 및 흑대추 추출물의 농도가 증가함에 따라 증가하였으며, 열수 및 에탄올 추출물에서는 건대추에 비해 발효 흑대추 추출물의 저해활성이 높았다. 이상의 결과로 발효 흑대추의 열수 및 에탄올 추출물에서 높은 항산화 활성을 확인 할 수 있었으며, 발효 흑대추는 우수한 기능성 식품으로서의 가능성을 확인할 수 있었다.

본 연구에서는 미생물을 이용하여 감귤과피 발효를 실시하고, 발효 추출물의 생리활성 변화를 확인하였다. 분말화시킨 온주밀감 과피에 Aspergillus niger를 첨가하고 5일간 진탕 배양하고 감귤발효물을 ethyl acetate로 추출하였다. 대조구는 발효 전 감귤과피 추출물을 사용하였으며, 각 추출물의 성분변화는 HPLC를 이용하여 분석하였다. 그 결과, neohesperidin 함량이 현저히 증가하면서, 발효에 의해 compound 1, 2가 생합성되었다. 감귤발효 추출물의 항염 활성은 LPS로 염증을 유발시킨 RAW 264.7 macrophage cell에서 확인하였다. 감귤발효 추출물이 대조군에 비해 NO (Nitric oxide) 생성이 유의적으로 감소하였으며, 염증반응과 관련된 단백질 iNOS와 COX-2 의 발현도 감귤발효 추출물에서 유의적으로 감소하였다. 감귤발효 추출물은 pro-inflammatory cytokine인 TNF-${\alpha}$와 IL-6 생성을 억제하는 효과도 나타내었다. 본 연구 결과를 통하여 감귤 과피의 flavonoid 배당체 화합물들을 aglycone 형태로 전환함과 동시에 유효 생리활성 성분의 효능을 증대시켜 부산물로서 발생되는 감귤의 새로운 활용 방안으로 기대된다.

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. Content of the marker substances did not increase in all fermentation experiment group.
