This study was aimed to evaluate an agonistic activity to benzodiazepine receptor of several medicinal plants, which have been used as sedatives in oriental medicine. Methanol extracts of medicinal plants which were used in this study inhibited the binding of $[^3H]Ro15-1788$, a selective benzodiazepine receptor antagonist to benzodiazepine receptor of rat cortices. Inhibitory activity of Cyperus rotundus was observed to be the highest among the tested medicinal plants. Methanol extracts of Cyperus rotundus and Zizypus jujuba inhibited a $[^3H]flunitrazepam$, a selective benzodiazepine receptor agonist, binding to benzodiazepine receptor. GABA significantly enhanced the inhibition of $[3H]flunitrazepam$ binding by Cyperus rotundus and Zizypus jujuba, and these positive GABA shifts supported the strong possibility of agonistic activity to benzodiazepine receptor. From these results, it may be concluded that the substance or substances with neurochemical properties characteristic of a benzodiazepine receptor agonist may be important components and contribute to the sedative property of these medicinal plants.

최근 대한 약사회에서 오래된 약물의 섭취로 인한 부작용을 예방하고 약물에 의한 환경오염을 예방하자는 내용으로 공공 광고를 하고 있다. 또한 의약분업으로 인한 약물 남용을 예방하고자 하였으나, 약물 처방의 복잡한 절차와 약물처방 비용만 증가시켰다. 현 상황을 벗어나기 위한 좀더 효율적인 시스템의 도입이 필요하게 되었다. 유비쿼터스와 융합 기술이 IT 분야의 트랜드가 되었으며, 본 연구에서는 이러한 기술을 이용한 약물 남용 및 관리를 위한 정보시스템의 프로토타입을 설계하고자 한다.

This study was carried out to examine antimicrobial substances from medicinal plants, the ethanol extracts of 38 medicinal plants were tested for the antimicrobial activity against Staphylococcus aureus ATCC 25923 and methicillin-resistant Staphylococcus aureus ATCC 43300. The extracts of Glycyrrhiza uralensis, Sophora flavescens, Dryopteris crassirhizoma, and Pinas densiflora showed significant antimicrobial activities against both S. aureus ATCC 25923 and methicillin-resistant S. aureus ATCC 43300. The extract of Dryopteris crassirhizoma among these medical plants showed the highest antimicrobial activity. These results suggested that the extracts from Dryopteris crassirhizoma, Sophora flavescens, Pinas densiflora, and Glycyrrhiza uralensis could be the potential source of antimicrobial agents against methicillin-resistant S. aureus and S. aureus.

Atherosclerosis is a widespread and chronic progressive arterial disease that has been regarded as one of the major causes of death worldwide. It is caused by the deposition of cholesterol, fats, and other substances in the tunica intima which leads to narrowing of the blood vessels, loss of elasticity, and arterial wall thickening, thus causing difficulty in blood flow. Natural products have been used as one of the most important strategies for the treatment and prevention of cardiovascular diseases for a long time. In recent decades, as interests in natural products including medicinal herbs have increased, many studies regarding natural compounds that are effective against atherosclerosis have been conducted. The purpose of this review is to provide a brief overview of the natural compounds that have been used for the treatment and prevention of atherosclerosis, and their mechanisms of action based on recent research.

Dynamic parameters of biochemistry including the POD (peroxidase) activity, contents of DNA and RNA, isozymes of POD and ES (esterase) in American send (Panax quinquefolium L.) seed are reported in the present paper. The dynamic changes of POD activity proved that the PAS (physiological afterripening stage) is a stage in which some substances are prepared for seed germination. The POD activity correlated with ER (embryo ratio) significantly DNA content changed little only within 0.0036∼0.013 mg/ml, which did not correlate with ER. RNA content changed from 0.1539 to 1.0313 mg/ml and correlated significantly with RE during all of the embryo afterripening. None of the POD isozyme band was obtained in ESGS (embryo slowly growth stage), but five bands in ERGS (embryo rapidly growth stage) and six bands in PAS. Four bands of ES isozymes were obtained in ESGS, but six bands in ERGS, particularly, the content of ES isozymes increased in PAS. All of these may provide some information for understanding the dormancy mechanisms of American song seed.

Background and objective: Artemisia argyi has a long history as an effective treatment for various diseases. The detection of environmental pollutant benzo(a)pyrene, a known human carcinogen, in the leaves of Artemisia argyi is cause for concern. For medicinal plant extracts, both a reduction of benzo(a)pyrene as well as the maintained effectiveness of the compound are important. Therefore, in this study, we propose an optimized process for the addition and filtration of activated carbon to reduce benzo(a)pyrene and change the contents of the indicating substance(jaceosidine and eupatilin). Methods: Artemisia argyi EtOH extract containing 36 ppb of benzo(a)pyrene was added to 0.1, 0.5, 1.0, and 1.5% (w/w) of activated carbon for 120 min and filtered using an activated carbon filter 1, 2, 3, and 5 times respectively. The content of benzo(a)pyrene and indicating substances in Artemisia argyi extract were then measured with high performance liquid chromatography (fluorescence and UV detectors). Results: As the amounts of activated carbon powder and filtering cycles increased, the content of benzo(a)pyrene in the Artemisia argyi extract decreased. However, when activated carbon powder 1.5% was added to the extract, and when the activated carbon filter was filtered five times, the results were reduced by 15% and 30~40% respectively. The optimal extraction condition for reducing benzo(a)pyrene was adding 1.5% of activated carbon powder. This resulted in reducing benzo(a)pyrene by 83% and indicating substances by about 4%. Conclusions: Here we present a process for reducing benzo(a)pyrene in Artemisia argyi extract using activated carbon to reduce toxicity and minimize the loss of active ingredients. This approach has potential application within a manufacturing process of various medicinal plant extracts.

The total phenolic contents and antioxidative activities of the ethanol and methanol extracts from 9 Korean medicinal herbs were tested for the application of skin care products such as soaf and lotion. For the evaluation of antioxidative activity of the extract the method of electron donating ability with resolution reagent DPPH(1 ,1-diphenyl-2-picryl hydrazyl) and TBARS (Thiobarbituric acid reactive substances) value were used in comparison with α-tocopherol and BHA. As the results, the total phenolic contents of the extracts calculated as chlorogenic acid were ranged from 0.063-0.124 mg/ml. All the medicinal plant extracts showed some appreciable antioxidative effects. Among them, Zanthoxylum piperitum, Cinnamomum cassia and Caesalpinia sappan were shown to have relatively high antioxidative effects comparable with BHA and α-tocopherol..

Medicinal fungi, taken whole or as various forms of extracts, have been used to alleviate, cure or prevent human ailments since pre-historic times. In particular, Asian cultures have incorporated a variety of mushrooms into their medical practices. Chemically pure, bioactive metabolites from fungi have been a mainstay of modern pharmacological research and in addition to antibiotics, include anticancer agents, immunosuppressants, enzyme inhibitors, antagonist and agonists of hormones, and a variety of psychotropic substances. However, to date not many studies have focused on the possible health benefits of odorant volatile organic compounds (i.e., gas phase compounds). An analysis of these compounds for their health related effects will expand the range of compounds available for the treatment of chronic and acute diseases. This review highlights phenolic acids and monoterpenes from Asian medicinal mushrooms (AMMs), which not only produce pleasant odors but also have antioxidant and antibacterial effects. Odorant bioactive volatile phase compounds from medicinal mushrooms remain an essentially untapped source for future medicines, and AMMs remain a promising resource for future pharmacological research.

약용식물 67종의 생리활성 부위를 대상으로 열수 추출물이 in vitro에서 xanthine oxidase의 활성에 미치는 효과를 확인하였다. 약용식물 중에서 황금, 지각, 하수오, 갈근, 청피, 복분자, 녹차 및 지실 추출물은 xanthine oxidase의 활성을 강력하게 저해하여 항통풍 천연소재로서의 활용 가능성이 높게 나타났다. 하수오 뿌리 추출물은 열과 pH에 대한 안정성이 우수하였고, 농도에 비례하여 xanthine oxidase의 활성을 저해하였다. 하수오 추출물은 2.0 mg/0.1 mL의 농도에서 xanthine oxidase에 대해 73.8%의 저해 효과를 나타내었다.
