This study was examined adsorption ability of heavy metal Hg(I), Pb(II), and U(Vl) ion use of fruit from schizandra chinensis, The fruits of schizandra chinensis sample used breaking into fragments $50{\sim}100$ mesh. The sample solution was mixed fruits of schizandra chinensis and heavy metal ion. Each heavy metal ion of into solution was quantum analysis with ICP-AES. As the result, each condition of maxium adsorption ability of heavy metal ion was high in the range of pH 5-7, adsorption time was about 15 minutes, and the optimum temperature was $100^{\circ}C$. The heavy metal ion was increased adsorption in order of increasing concentration and in ethanol solution better than in aqueous solution.

OBJECTIVES : Schizandra chinensis is well known for its efficacy at liver function reinforcement, relieving thirst and recovery from fatigue. In this study, we examined the effects of sports drink containing Schizandra chinensis on serum metabolic substrate, electrolyte, stress indicators, related-enzyme and exercise performance, rectal temperature, and heat shock proteinb70 (HSP70). METHODS : Elite long-distance runners (male, 21.3yrs, n=16) were selected and divided into two groups; an experimental group (EXP, n=8) and a control group (CON, n=8). A beverage containing Schizandra chinensis was supplemented 3 times per day to EXP for 4 weeks. Serum biochemical elements (glucose, lactate, total cholesterol, triglyceride, high density lipoprotein cholesterol, glutamate oxaloacetate transaminase, glutamate pyruvate transaminase, creatinine, creatine phosphokinase, lactate dehydrogenase, blood urea nitrogen, Na, K, Cl) were analyzed by auto blood analyzer. Exercise performance was measured by treadmill exercise test, HSP70 was detected by electrophoresis and Western blotting, and rectal temperature was measured by rectal temperature probe. RESULTS : Administration of the beverage increased significantly the rest level of blood Na, Cl and glucose and decreased significantly lactate dehydrogenase, glutamate oxaloacetate transaminase. No difference was found in exercise performance, rectal temperature increment or HSP70 concentration between groups. CONCLUSIONS : Administration of a sports drink containing Schizandra chinensis altered blood glucose, lactate dehydrogenase, glutamate oxaloacetate transaminase, Na and Cl levels.

오미자 씨 오일의 화장품 소재로서 가능성을 평가하기 위해 GC와 GC/MSD를 사용하여 안정성 평가 및 성분 분석을 실시하였다. 그 결과 주요성분은 팔미틱산과 올레익산으로 나타났다. 오미자 씨 오일은 열에 의한 성분변화가 없고, 소재 자체의 안정성이 뛰어난 것으로 나타났다. 또한, DPPH(1,1-Diphenyl-2-picrylhydrazyl) 라디칼 소거능 실험을 통하여 항산화 효능을 측정한 결과 오미자 씨 오일이 마카다미아 오일과 올리브 오일에 비하여 높은 항산화 효능을 나타내었다. 콜라겐 합성능 또한 뛰어난 것으로 평가되었다. 따라서, 오미자 씨 오일은 화장품 소재용으로 유용하게 활용될 수 있는 가능성을 가진 것으로 평가되었다.

This studies were carried out to investgate the effects of omija (Schizandra chinensis) extracts(OE) on the growth of lactic acid bacteria (LAB, HYO-1 and HYO-2) isolated from home-made kimchi. The growth of isolated LAB was inhibited apparently in modified MRS broth containing 1% or 2% of OE. The growth of isolated LAB was inhibited by pH control with HCI to 4.3 or 3.7, the same pH of modified MRS broth containing 1% or 2% of OE. The strong growth inhibitory properties against isolated LAB were shown by fumaric and itaconic acid among various organic acids of Schizandra chinensis, such as citric acid, malic acid, lactic acid, fumaric acid, itaconic acid and acetic acid. The isolated LAB were indentified as Lactobacillus plantarum.

To search for new chitin biosynthesis inhibitors from natural sources, several higher plants were examined the inhibitory activity against chitin synthase IIby enzymatic assay. Among them, the extract of Schizandra chinensis strongly showed the inhibitory activity against chitin synthase II. Gomisin N and wuweizisu C were isolated from Schizandra chinensis and showed $IC_50$ value of $62.4{\;}\mu\textrm{g}/ml$ and $19.2{\;}\mu\textrm{g}/ml$, respectively. Activities of these compounds were more stronger than that of polyxin D. However, gomisin N and wuweizisu C showed weakly antifungal activities against various human pathogens.

The purpose of this study was to determine the effect of rat intestinal a-glucosidase inhibitor; methanol $(80\%)$, ethanol $(80\%)$ and water extract of Schizandra chinensis in Korea (KS: Schizandra chinensis in Korea) and China (CS: Schizandra chinensis in China). When the final concentration was 1 mg/ml for each sample (KS and CS), methanol extract of KS ($IC_{50}$ 1.62 mg/ml) showed $46.8\%$, ethanol extract of KS ($IC_{50}$ 1.48 mg/ml) showed $47.4\%$, water extract of KS ($IC_{50}$ 1.72 mg/ml) showed $46.3\%$ and methanol extract of CS ($IC_{50}$ 8.35 mg/ml) showed $13.3\%$, ethanol extract of CS ($IC_{50}$ 8.05 mg/lml) showed $16\%$, water extract of CS ($IC_{50}$ 8.37 mg/ml) showed $11.54\%$ of inhibitor for p-nitrophenyl $\alpha-D-glucopyranoside$ (pNPG) $\alpha-glcosidase$ activity, respectively. And the contents of total phenol, flavonoid of Schizandra chinensis were measured. When the final concentration was 1mg/ml for each sample (KS and CS), total phenol and flavonoid in KS were higher than CS, respectively. The order superoxide dismutase (SOD) activity $IC_{50}$ values of each solvent extracts of KS were: 2.006 mg/ml methanol extract, 2.304 mg/ml ethanol extract and 2.5 mg/ml water extract, which were higher than that of each solvent extracts CS as: 2.881 mg/ml methanol extract, 3.085 mg/ml ethanol extract and 3.190 mg/ml water extract.

전라북도 장수군 오미자 자생지 토양 및 환경특성을 평가하기 위해 식생, 입지환경 및 토양조사를 수행한 결과는 다음과 같다. 오미자는 고도 500~700 m의 준산간지 산록 북서쪽 방향의 계곡에 자생하고 있으며, 경사도는 17.6~36.4%, 토층은 마사토와 부엽토가 쌓여 배수가 용이한 지반이 형성된 지역에 주로 분포하는 것으로 나타났다. 오미자 자생지 식물상은 34과 55종으로 나타났다. 갯버들은 거의 모든 조사지점에서 분포하였으며, 칡, 싸리, 옻나무, 쑥과 같은 식물의 세력이 자생지 내에서 왕성한 것으로 나타났다. 오미자 자생지 토양의 화학적인 지표는 우리나라 일반 오미자 인공재배 토양과 비교시 식물영양물질이 풍부하고 완충능력이 더 우수한 것으로 조사되었다. 따라서 오미자 인공재배 적지분석 및 기후변화에 따른 재배지역 이동에 따른 재배기술 확립시 자생지 토양특성을 고려한 합리적인 토양관리가 필요할 것으로 판단된다.

오미자 물 추출액을 첨가한 드링크 타입 요구르트를 개발하기 위한 기초 연구로 오미자 물 추출액 제조를 위한 최적 추출 조건을 확립하였고, 오미자 물 추출액이 유산균의 생육에 미치는 영향을 조사하였으며 오미자 물 추출액 첨가 드링크 타입 요구르트를 저장하는 동안 유산균의 변화를 관찰하였다. 오미자의 최적 추출 조건은 오미자를 50배수의 물로 추출 온도 2$0^{\circ}C$에서 15시간 추출하는 것이 가장 적합하였으며, 추출액의 pH는 3.07, 산도는 2.39%, 당도는 1.10%, 색 흡광도는 0.15이었다. 오미자 물 추출액의 첨가 농도(0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9와 1.0%)에 따른 유산균 증식에 미치는 영향을 조사한 결과 12시간 배양에서 Lac. acidophilus가 0.9% 첨가에서도 가장 안정된 생육을 보였으며 그 다음이 Lac. casei, Lac. bulgaricus와 Str. thermophilus 순으로 각각 오미자 물 추출액 0.8%, 0.2%, 0.1% 첨가 수준에서 생육이 유지되었다. 따라서 오미자 물 추출액 첨가 드링크 타입 요구르트 제조시 Lac. acidophilus를 starter로 사용하는 것이 가장 적절하였다. 오미자 물 추출액을 0.4%, 0.6%, 0.8%, 1.0%첨가하여 제조한 드링크 타입 요구르트를 4$^{\circ}C$에서 15일 동안 저장하였을 때 15일째의 유산균수는 각각 1.77${\times}$$10^{9}$ CFU/mL, 2.29${\times}$$10^{9}$ CFU/mL, 1.27${\times}$ $10^{9}$ CFU/mL, 1.13${\times}$$10^{9}$ CFU/mL로 약간 감소하였으나 0일의 기준 시료와 큰 차이 없이 유사한 균수를 유지하였다. 이것은 축산물의 가공 기준 및 성분 규격에 나타난 농후 발효유의 법적 유산 균수(1.0${\times}$$10^{8}$ CFU/mL 이상)를 충족하는 것으로 나타났다.

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.
