Berberis koreana Palibin belonging to Berberidaceae family, a common herb in Korea, has been contained some quantity of Berberine analogue and other ingredients. Authors therefore paid attention to its pharmacological actions and examined the effects on sleep duration and rectal temperature in mouse with crystal (A) from Berberis koreana Palibin in Korean native plans. The experiment searching for the effect on sleep duration was performed with pretreatment of Berberis Koreana Palibin crystal (A) 30 min before the administration of 25 % ethanol, and its crystal were also administered intraperitoneally with the intention to examine the effect on rectal temperature in mouse. The results of the experiment were as follows; 1. Crystal (A) from Berberis koreana Palibin was made by extraction with ethanol and HCI. 2. Crystal (A) enhanced the hypnotic activity of alcohol in concentratins of 0.1 mg/10g or 0.15 mg/10g. 3. Rectal temperatures in mice were significantly reduced with administration of crystal (A) in concentrations of 0.1 mg/10g or 0.15 mg/10g. 4. The maximal reduction of rectal temperature and potentiation of the hypnotic activity were observed at 30 min after its administration. From the above results, it is clear that crystal (A) from Berberis koreana Palibin exerts the potentiation of hypnotic action of alcohol and reduction of rectal temperature in normal mouse. Its pharmacological effects are probably derived from the action upon the central nervous system.

The present study was carried out to investigate the antidiabetic and antioxidant effect of methanolic extract of Berberis tinctoria leaves (MEBT), in streptozotocin induced diabetic rats. Oral administration of MEBT extract (150 mg/kg and 300 mg/kg) for a period of 14 days. Blood glucose levels, body weight food and liquid intake were measured on every $5^{th}$ day over a period of 14 days. In diabetic rats, MEBT at the dose of 150 mg/kg and 300 mg/kg body weight resulted in significant reduction in blood glucose levels. The study was further investigated to determine antioxidant and antihyperlipidemic potential of MEBT in streptozotocin (STZ) induced diabetic rats. These results suggest that the MEBT possess antidiabetic activity and is able to ameliorate biochemical damages in STZ induced diabetic rats and the results were found to be in a dose dependent manner.

Berberis is an important medicinal plant, of the family Berberidaceae. Different Berberis species and their parts are very common in herbal drug markets of India and world over as an adulterant/substitute to 'Daruharidra' i.e. B. aristata DC. Antimicrobial activity of 50% hydroalcoholic extracts of stem of four Berberis species viz. B. aristata DC., B. asiatica Roxb. ex DC., B. chitria Lindl. and B. lycium Royle and the isolated alkaloid berberine were tested against eleven bacterial and eight fungal strains. The extracts with the strongest antibacterial activity was obtained from B. lycium followed by B. aristata, B. asiatica and B. chitria. Based on these results it is possible to conclude that the hydroalcoholic extract and alkaloid (berberine) has stronger and broader spectrum against bacterial strains as compared to fungal strains. The result obtained in the present study authenticates and support the use of these plants in folklore medicine for treatment of various infectious diseases caused by the bacterial pathogens. However, an attempt has been made to explore the possibilities of utilizing stem part rather than roots of these species with the aim to conserve this species which is over exploited due to diverse use of its root. These findings will stimulate the search for novel, natural products as new antibacterial/antifungal agents which may be useful to pharmaceutical industries.

The aerial parts of Epimedium koreanum Nakai have been used to stimulate hormone secretion in treating impotence. Ten flavonol glycosides, 3,4,5-trihydroxy-8-prenylflavone 7-O-[${\beta}$-D-glucopyranosyl($1{\rightarrow}2$)-${\beta}$-D-glucopyranoside] (1), hyperoside (2), icarisid II (3), 2"-O-Rhamnosylicarisid II (4), epimedin A (5), epimedin B (6), epimedin C (7), icariin (8), hexandraside E (9), and epimedoside A (10) were isolated from the an ethylacetate soluble extracts of the aerial parts of Epimedium koreanum Nakai through activity-monitord fractionation and isolation method. The structures of compounds 1 - 10 were elucidated by high resolution fast atom bombardment mass spectrometry and two dimentional nuclear magnetic resonance spectroscopy analysis. Compounds 1 and 4 showed potent antioxidant activity, with $IC_{50}$ values of 19.7 and 11.5 ${\mu}g$/mL and 88.2 and 90.5 ${\mu}M$, respectively.

The objective of this study is to characterize a toxicity of Epimedii Herba (EH) in F344 rats and to find a dose levels for the 13 weeks toxicity study. EH is well known as medicinal herb in many Asian countries for traditional medicines of antibacterial and antiviral effects, estrogenic and antiestrogenic effects, and for treatment of osteoporosis, hypotensives, fatigue, kidney disorders, and related complications. However, the indispensable and basic information of toxicological evaluation of EH extract is insufficient to support its safe use. Therefore, we conducted toxicological evaluation of this drug in compliance with OECD and MFDS guideline in this study. The extract of EH was administered orally to F344 rats at dose levels of 0, 500, 1000, 2000, 3500, and 5000 mg/kg/day for 2 weeks. Each group was composed of 5 male and female rats. In this study, there were no treatment of EH-related adverse changes in clinical observations, mortality, body weights, food consumption, urinalysis, gross finding at necropsy, and organ weight examination. Total red blood cell count, hematocrit, mean corpuscular hemoglobin concentration, total cholesterol, and phospholipid were decreased in males and females at 5000 mg/kg/day compared to the control animals. Mean corpuscular volume and reticulocyte counts were increased in males and females at 5000 mg/kg/day compared to control animals. Therefore, we recommend that dose level of 5000 mg/kg/day is a highest treatment group in 13-week EH extract exposure study for further toxicity assessment.

To know the anti-oxidative effect of Epimedii Herba (Berberidaceae), the methanol extract of this plant was investigated by using a Caenorhabditis elegans model system. The methanol extract of this plant showed relatively significant DPPH radical scavenging and superoxide quenching activities. The ethyl acetate soluble fraction of Epimedii Herba (EHE), which showed the most potent DPPH radical scavenging and superoxide quenching activities, was tested on its effects on superoxide dismutase (SOD), catalase, intracellular ROS, and oxidative stress tolerance in Caenorhabditis elegans. Furthermore, in order to verify that regulation of stress-response genes is responsible for the increased stress tolerance of the EHE treated C. elegans, we checked SOD-3 expression using a transgenic strain. As a result, the EHE increased SOD and catalase activities of C. elegans, and reduced intracellular ROS accumulation in a dose-dependent manner. Besides, EHE-treated CF1553 worms showed higher SOD-3::GFP intensity than that of non-treated controls.

본 연구에서 기존의 생리활성이 알려진 차가 버섯(Inonatus obliquus), 모링가(Moringa oleifera), 그라비올라(Anona muricata), 단풍마(Dioscorea quinquelaba), 가시오가피(Acanhopanax senticosus), 음양곽(Epimedii herba), 인진쑥(Artemisia capillaris), 그리고 오디(Morus alba) 추출물과 원두커피를 혼합하여 기능성 음료를 제조하였으며, 각각의 음료를 C1에서 C7으로 명명하였다. 각 음료의 항균, 항곰팡이, 항산화 활성 및 총 폴리페놀 함량을 조사하였다. 항균 및 항곰팡이에 대한 활성은 Gram positive bacteria인 Staphylococcus aureus에 대하여 C4, C5, C6 및 C7이 활성을 나타내었고, 특히 C7인 경우 항생제 내성균주인 MRSA에 대하여 강한 활성을 나타내었다. Gram negative bacteria에 대한 결과는 E. coli D31에 대하여 1.0 mg/ml의 농도에서 C1에서 C7 모든 음료가 활성을 나타내었고, 반면에 곰팡이인 Candida albicans에 대하여는 활성을 나타내지 않았다. 총 폴리페놀 함량은 C6의 경우가 7.37 mg/g으로 가장 높은 결과를 나타내었고, C5의 경우는 3.78 mg/g으로 가장 낮은 함량을 나타내었다. DPPH로 항산화 능력을 측정한 결과, C1에서 C7 모두 강한 활성을 나타내었고, 특히 C7인 경우 0.5 mg/ml의 농도에서 88%라는 높은 free radical 소거능력을 나타내었다. 이러한 결과를 바탕으로 각 기능성 음료의 생리활성의 기초자료를 제공하고 다양한 기능성 건강음료뿐 만 아니라 고부가가치 기능성 제품을 창출 할 수 있는 근거를 마련한 것으로 생각된다.

한국특산 매자나무(Berberis Koreana Palibin)의 뿌리에서 분리한 majarine은 isoquinoline 알카로이드로서 본 교실에서는 중추신경계에 대한 약리작용을 검토하고 있다. Majarine을 마우스 복강내로 투여하여 직장온도 변화와 haloperidol, cyproheptadine과 reserpine 등에 대한 약물 상호작용을 관찰하여 다음과 같은 성적을 얻었다. Majarine은 마우스에 있어서 용량의존적으로 현저한 체온감소를 나타내었으나, 0.1 mg/kg투여시 체온증가의 유의성을 보였다. 체온감소는 haloperidol과 cyproheptadine으로 억제되었다. Reserpine처치 마우스에 있어서 ${\alpha}$-methyl-p-tyrosine으로 전처치한 다음 majarine 2.0mg/kg 투여시 체온감소를 나타내었다. 이러한 결과로 보아 majarine의 체온변화는 dopamine과 serotonin수용체에 관련성이 있다고 사려되고, 체온감소는 dopamine수용체에 직접적으로 작용한다고 생각되는 바이다.
