This study was intended to investigate the capitulum morphology and to evaluate its taxonomic importance within the 23 taxa of Korean Artemisia L. The Korean Artemisia was classified into sterile subg. Dracunculus and fertile subg. Artemisia by the fertility of the disk florets, which is the traditional diagnostic character of subgenera. There are sections in subg. Artemisia: sect. Absinthium with a densely, sparsely hairy receptacle, and sect. Abrotanum and sect. Artemisia with a glabrous receptacle. However, A. fukudo and A. sacrorum belonging to sect. Abrotanum, and A. viridissima belonging to sect. Artemisia were observed to have sparsely hairy receptacles. Therefore, the presence of hair on a receptacle, which is now regarded as a key character distinguishing sections, has to be reevaluated. The whole shape and size of the capitulum, the characteristic of the stigma apex, the hair on the involucral bract, and the shape of the central or peripheral floret are thought to be the most valuable characters to consider in recognizing species.

Aspiring to the new raw materials of insecticides is one of the plant extracts. The material structure of a variety of plant extracts have because the material to the defense of the plant itself, the case of insecticides, using plant extracts, safe, has low toxicity and has the advantage of highly distinctive and fall. Coltsfoot (Tussilago farfara L.) is belonging to the family Compositae, and distributed in all parts of China as medicinal plants and indigenous plants used. Coltsfoot is known that it is effect to respiratory disease and has an antiviral effect. However, the reported insecticidal activity of coltsfoot could be not found. Fortunately, I found insecticidal activities when I was screening the bioassay against several insects with a lot of plant extracts. Using the ethanol extract of the Tussilago farfara, there were insecticidal activities against Culex pipiens pallens and Tetranychus urticae. There were several fractions in ethanol extract of coltsfoot by using various organic solvents. Hexane fraction showed a higher insecticidal activity than any other fraction. It is confirmed that hexane fraction contained pyrethrin by using HPLC analysis. So, it might be suggested that extract of coltsfoot has an insecticidal activity and its effect due to a ingredient of pyrethrin.

Hanyak, Korean herbal medicine is defined as the herbs understood and explained by traditional Korean medical theories. Considering this definition, there are broad prospective of every species being consilienced and utilized as Korean herbal medicine. Most varied plant species are in tropical regions, and its of these regions posses its own particular traditional medicine. Brazil posses the most varied and abundant plant species and also characteristic traditional medicine, formed by the combination of native indians and immigrants from Africa and Europe. Brazilian traditional medicine are practices by 'garrafeiros', 'raizeiros', or 'curandeiros' and in Caatinga uses herbs in ritual ceremonies. But threatened by modernization, these knowledge may be vanished in a prompt time. Therefore we carried this research in the propose of understanding as well as preserving their traditional medical knowledge. We revised publications about the medical plants and summarized 314 species of 94 families according to repetitive references. The most cited families were COMPOSITAE, LABIATAE, LEGUMINOSAE, RUBIACEAE, SOLANACEAE, UMBELLIFERAE, VERBENACEAE. Also cited major medical efficacies which further medical uses in combinations or modification of current traditional Korean medicine should be studied. This study provides overall prospect of the plants resources of Brazil and their uses. It may serve in the consilience and understanding of varied traditional medicine by traditional Korean Medicine.

A palustrine wetland is a type of a wetland that prevails in Korea as well as an ecosystem that provides various ecological functions and has affluent biodiversity. This study was conducted to understand the characteristics of vegetation in a palustrine wetland by analyzing a life form and naturalized plants, in order to present the maintenance and utilization plan of a small wetland. A total of 249 taxa including 76 families, 188 generics, 209 species, 38 varieties and 2 forma were found at six investigated wetlands. As a result of the appearance ratio analysis, Therophytes (37.8%) with 94 taxa and Hemicryptophytes (31.3%) with 78 taxa were in order of life form, and Gramineae (14.1 %) with 35 taxa and Compositae (11.2 %) with 28 taxa were in order of family level. These were deemed representative vegetation in a palustrine wetland. Equosetum arvense, Phragmites communis, Commelina communis, Persicaria thunbergii, Arenaria serpyllifolia, Stellaria media, Erigeron annuus, Erigeron canadensis and Artemisia princeps var, orientalis were found continuously for a period of investigation in all sites. Equosetum arvense, Phragmites communis and Persicaria thunbergii were species with high appearance frequency. Especially, Persicaria thunbergii was construed high in a cover ratio in May as it develop first among Hydrophytes and form a canopy sooner than anything else. We found that a degree of naturalization and an urbanization index appear comparatively high in Yeongok-ri, Cheonan, Gangjang-ri, Asan and Yodang-ri, Hwasung, which is construed due to artificial interference, such as fanning, fishing, swimming and green-tour program. These results would be used to utilize in restoring a deserted and damaged wetland and to provide fundamental data in creating a wetland as follows.

Artemisia messes-schmidiana var viridis(Compositae) has been used for jaundice, hepatitis, diuretic and liver cirrhosis etc. 1-naphthylisothiocyanate(ANIT) has been used as a model compound to study mechanisms of intrahepatic cholestasis in laboratory animals as rat and mouse. The purposes of present study are to examine pharmacological effects of Artemisia messes-schmidiana var viridis water extract(AMWE) on alterations of triacylglycerol, cholesterol, protein, albumin and A/G ratio levels in serum, of histopathological appearances of liver, and that of hepatic microsomal cytochrome P-450 contents. Increased serum triacylglycerol levels by ANIT were significantly decreased with AMWE. However, AMWE posttreatment aggravated ANIT-induced cholesterol increase. Serum total protein and albumin contents, and A/G ratio were decreased in all ANIT-treated groups, and there were increased compared with control by AMWE posttreatment. Hepatic microsomal cytochrome P-450 contents were decreased in either AMWE and ANIT treatment, which greatly increased with AMWE pretreatment. On the other hand, in histological findings, our results shown that ANIT induced increase of lipid droplets and widening of sinusoidal capillary and these phenomena were disappeared with AMWE treatment. In conclusion, AMWE have choleresis effect. Also, AMWE improved lipid metabolism, protection and regeneration of hepatocytes in ANIT-induced cholestasis.
