Objective : Obesity in modern society has a significant impact on pathological, psychological and social problems. Therefore, many studies on obesity treatment using herbal extracts with fewer side effects have been conducted. This study was designed to investigate the effect of inhibiting fat accumulation in vitro in order to Mongolian medicinal plants find anti-obesity candidate among. Methods : We measured pancreatic lipase inhibitory activity in Mongolian medicinal plants extract. Cytotoxicity of these extracts was monitored in 3T3-L1 cells by MTT assay. In addition, the anti-obesity effects was confirmed at concentrations of 0.2, 0.1 and 0.05 mg/㎖ through Oil red O staining. Results : Among Mongolian medicinal plants, Rheum undulatum roots in September (RURS), Paeonia anomala L. (PAL), and Fragaria orientalis (FO) showed the highest pancreatic lipase inhibitory activity. As a result of the MTT assay, more than 80% was judged to be non-toxic, and the concentration was determined, and as a result of evaluating the lipid accumulation inhibitory effect, 6 types were selected as candidates. Conclusion : Based on these results, the top 7 species expected to be used as anti-obesity functional materials were selected. However, additional efficacy verification and mechanism of action need to be established in the future. So, it is expected that the medicinal plants verified through this will be used as functional materials for the prevention and treatment of obesity.

Over the past decade there has been a resurgence of interest in botanical products for their medicinal uses. This present study was designed to screen medicinal plants for the treatment of brain diseases such as Alzheimer's disease or aging. We tested the effects of the water extracts from 41 species medicinal plants on acetylcholinesterase (AChE) inhibition and antioxidant activity in vitro. Among them, Euodia rutaecarpa, Rubus coreanus, Achyranthes japonica, Morus alba, Salvia miltiorrhiza, Liriope platyphylla, and Rheum palmatum showed relatively AChE inhibition potency over 80%. Among the 7 medicinal plants investigated, E. rutaecarpa showed an 25%, 65%, and 93% inhibitions on AChE activity at 2.5, 12.5, and 25 ㎍/㎖ of the extract, respectively and was found to be one of most potent AChE inhibitor. The water extracts from 4 species (E. rutaecarpa, R. coreanus, A. iaponica, and M. alba) were tested on their antioxidant capacities using radical scavenging effect against ABTS/sup ㆍ+/. Among the 4 medicinal plants investigated, both R. coreanus and E. rutaecarpa showed significant antioxidant capacity. Therefore, E. rutaecarpa and R. coreanus are expected to ameliorate the clinical symptoms in Alzheimer's disease due to significant AChE inhibition and radical scavenging effect.

This study aims to demonstrate the effect of farming technology on introducing medicinal plants (MP) and wild food plants (WFP) into a traditional agricultural system within peri-urban zones. Field investigations and semi-structured focus group interviews conducted in the Buhozi community showed that 27 health and nutrition problems dominated in the community, and could be treated with 86 domestic plant species. The selected domestic MP and WFP species were collected in the broad neighboring areas of the Buhozi site, and introduced to the experimental field of beans and maize crops in Buhozi. Among the 86 plants introduced, 37 species are confirmed as having both medicinal and nutritional properties, 47 species with medicinal, and 2 species with nutritional properties. The field is arranged in a way that living hedges made from Tithonia diversifolia provide bio-fertilizers to the plants growing along the hedges. The harvest of farming crops does not disturb the MP or WFP, and vice-versa. After harvesting the integrated plants, the community could gain about 40 times higher income, than from harvesting farming crops only. This kind of field may be used throughout the year, to provide both natural medicines and foods. It may therefore contribute to increasing small-scale crop producers' livelihood, while promoting biodiversity conservation. This model needs to be deeply documented, for further pharmaceutical and nutritional use.

To study the health promoting effects of medicinal plants, 30 medicinal plants commonly available in Korea have been evaluated for their antioxidant compounds and antioxidant and antiproliferative activities. Total polyphenolics and flavonoids in the methanolic extracts were measured by spectrophotometric methods and 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radical scavenging activities and chelating effects have been determined for antioxidant activities. Moreover, the effects of medicinal plants on cell proliferation of intestinal (Caco-2) and pituitary (GH3) tumor cells were investigated using thiazolyl blue terazolium bromide (MIT) assay. The methanolic extracts of Pueraria thunbergiana and Artemisiae asiatria contained the highest total polyphenolic and flavonoid contents, respectively. P. thunbergiana exhibited the highest antioxidant activities. A. asiatria showed the strongest antiproliferative activity against Caco-2 and Ponciruc trifoliata Rafin and Lophathrum gracile Bronghiart exhibited the highest activities against GH3. Although there was positive correlation between ABTS radical scavenging activity and polyphenolic contents ($R^2=8189$), no relationship was found between antiproliferative and antioxidant activities.
