The objective of this study was determined to evaluate ${\alpha}$-amylase, ${\alpha}$-glucosidase, pancreatic lipase inhibition in vitro and DPPH radical scavenging activity of the several Korean resources plants. The ${\alpha}$-amylase inhibitory activity of Salicornia herbacea, Erythronium japonicum (flower) and Phragmites communis (root) in water extract showed relatively high 62.8%, 66.5% and 69.3%, respectively. The ${\alpha}$-amylase inhibitory activity of Citrus junos (pericarp) and Cornus officinalis in methanol extract was found to have an effect with 32.8% in Citrus junos (pericarp) and 60.9% in Cornus officinalis. Corylopsis coreana in both water and methanol extract had the highest ${\alpha}$-glucosidase inhibitory activity of 81.7% and 89.5%, while the extract of Portulaca oleracea, Ficus carica and Citrus junos was not measured ${\alpha}$-glucosidase inhibitory activity at given experiment concentration. Depending on the extraction solvent and the plant species, it was observed that there was a significant difference in ${\alpha}$-glucosidase inhibitory activity. The pancreatic lipase inhibitory activity showed relatively higher in the methanol extract than water extract except pericarp of Citrus junos. The DPPH radical scavenging activity of selected plants was much difference between measured plant species, and showed that the increase was proportional to the concentration. These results suggested that selected plants had the potent biological activity on carbohydrate, lipid Inhibitory activity and antioxidant activity, therefore these plant resources could be a good materials to develop medicinal preparations, nutraceuticals or health functional foods for diabetes or obesity.

Objectives: This study was undertaken to evaluate anti-glycemic and anti-lipid effects of Supungsunkihwan-gagambang, which is composed of Cornus officinalis, Dioscorea Batatas Decaisne, Auantii fructus and Platicodon grandiflorum. Methods: Diabetes was induced in ICR male mice ($24{\pm}1g$) with Surwit's high fat and high sucrose diet. Mice were divided into 3 groups (n=10) of normal, control and Supungsunkihwan-gagambang. The Supungsunkihwan-gagambang group was given 5% herbal medicine in their diet. The animals were fed on each experimental diet for 8 weeks. Body weight was assessed every week. At the 7th week, the fasting blood sugar (FBS) and oral glucose tolerance test (OGTT) were conducted in all experimental groups. After 8 weeks, fructosamine, lipid profile, epididymal fat weight, liver weight and white adipose tissue (WAT) size were measured. Results: Supungsunkihwan-gagambang significantly reduced FBS, OGTT and fructosamine. It also increased high density lipoprotein (HDL) cholesterol and significantly reduced triglyceride/HDL cholesterol ratio, total cholesterol/HDL cholesterol ratio and WAT size. Conclusions: These results show that Supungsunkihwan-gagambang improves anti-glycemic and anti-lipid effect in high fat diet-induced obese mice. Therefore we suggest that Supungsunkihwan-gagambang could be an effective treatment for patients with type 2 diabetes.

The antioxidant potential and enzyme activities in Salicornia herbacea, Corylopsis coreana, Erythronium japonicum, Phragmites communis, Momordica Charantia, Nelumbo nucifera, Salvia plebeia, Portulaca oleracea, Ficus carica, Citrus junos and Cornus officinalis were determined. Their antioxidant activities were measured using DPPH radical scavenging and nitrite scavenging activity. Enzyme activities in investigated plants were evaluated as superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), and ascorbate peroxidase (APX). The DPPH scavenging rate from 100 to 2500 $mgL^{-1}$ was the highest in the flower of Corylopsis coreana. However, it was not detected in most of the samples at concentration below 100 $mgL^{-1}$. The nitrite scavenging activity according to each kind of resource plants was significantly higher in the stem of Corylopsis coreana and leaf of Nelumbo nucifera. The root extract of Erythronium japonicum had the highest SOD enzyme activity of 94.0% while leaf of Salvia plebeia showed the lowest SOD enzyme activity of 30.4%. The activity of CAT and APX showed higher values in the stem of Corylopsis coreana, root of Erythronium japonicum and root of Phragmites communis in comparison with other plants. The activity of POD showed significantly high values in stem of Corylopsis coreana, Momordica Charantia and pericarp of Citrus junos extracts. The antioxidant enzyme activities differ significantly in different plants. In conclusion, we showed that Corylopsis coreana, Erythronium japonicum Cornus officinalis, and Momordica Charantia had the potent biological activities. Therefore, these plant resources showing antioxidant activity could be good materials for development of source of functional healthy food.

In this study three types of domatia; Tuft (T), Pocket-Tuft (PT) and Pocket (P) were observed on some species of the genus Cornus. Cornus officinalis Sieb & Zuee and C. florida Linnaeus possess T type, C. controversa Hemsl and C. walteri Wangerin possess PT type while C. alba Linnaeus possess P type. A total of 120 leaves were investigated for foliar mite's population. T type domatia was the habitat of 329 mites (48.89%), followed by PT type where 198 mites (29.41%) were found, and the least favored was the P type domatia that accommodated 146 mites (21.70%) out of 673 mites in total. The mean number of mites per domatia was $8({\pm}0.22)$, $4({\pm}0.95)$ and $3({\pm}0.70)$ for T, PT and P type, respectively. The alternative hypothesis that foliar mites prefer T type domatia as a habitat than PT and P type domatia was accepted based on these findings at a probability of P<0.05. Thus, it was concluded that foliar mites prefer T type domatia than the other two types. This could be due to the nature and efficiency of T type domatia in ensuring mites protection from predators and unfriendly environmental conditions. Therefore, the presence of denser tufts lowers the risks of predation and unfriendly environmental conditions and results in a higher number of mites.
