To verify allelopathic effects, seed germination and seedling growth test, chemical analysis and bioassay of selected species were carried out with naturally occurring chemicals of Artemisia capillaris. Seed germination ratio of Calamagrostis arundinacea. Youngia denticulata and Lactuca indica var. laciniata showed decrease in proportion to increase in aqueous extracts concentration of A. capillaris. while that of Cosmos bipinnatus and Leonurus sibiricus did not. However, dry weight growth of selected species treated with the same extracts as the above experiment was inhibited remarkably compared to the germination test. In the test at different concentrations of essential oil from A. capillaris, seedling growth of A. princeps var. orientalis and Plantago asiatica was suppressed according to the concentration of the essential oil, and root growth of the selected species was more inhibitory than that of shoot growth. Thirty-six chemical compounds were identified from A. capillaris plant by gas chromatography. Seven compounds out of 36 were bioassayed, and terpinen-4-ol was the most toxic among the tested substances.

Artemisia capillaris Thunb. and A. scoparia Waldst. & Kit. are classified by their root shape, leaf size and capitulum size. However, these characteristics are not nearly as useful when attempting to identify the two species owing to the continuous variation in them. Another important taxonomic characteristics is the habit, whether it is the subshrubs or perennial herbs of A. capillaris Thunb. or the annual or biennial herbs of A. scoparia Waldst. & Kit.. All observed specimens and living individuals in Korea are subshrubs or perennial herbs, and annual or biennial examples are not found. Therefore, it is considered that A. scoparia Waldst. & Kit. is not distributed in Korea.

This study was performed to investigate the influence of dietary and extract foods from A. capilliaris Thunberg on plasma and liver lipid metabolism in male Sprague-Dawley rats. For the experiment of liver and plasma lipid metabolism, Rats were find diets containing normal concentrations of fat or high concentrations of lard and two different preparations of A. capillaris Thunberg ; control diet (group C),50 mg/kg body weight A. capillary Thunberg methanol extract (group M), 6 g/kg diet A. capillary Thunberg dried powder (group P), high lard control diet (group L), 50 mg/kg body weight A. capillaris Thunberg with high lard (group LM) and 6 g/kg diet A. capillary Thunberg with hi\ulcorner lard (group LP). Effects of A. capillary Thunberg on plasma total cholesterol. High-density lipoprotein (HDL) cholesterol, Atherogenic index, triglyceride, plasma and liver peroxide contents, fatty acid composition of liver lipid and the distribution of fat droplets of liver. Supplementation of A. capillaris Thunberg resulted in lower plasma cholesterol, atherogenic index and triglyceride, and higher HDL-cholesterol in rats find high lard diets. However, these effects were not observed with low level of fat (groups C, M and P). A shift caused by feeding high lard diets in increased plasma and liver peroxides, saturated fatty arid composition of liver lipid and the more frequent distribution of fat droplets in liver could be reversed by feeding A. capillary Thunberg. This study suggests that A. capillary Thunberg co alter lipid metabolism in plasma and liver.

We investigated the antimicrobial activity of ether and ethylacetate fractions from Artemisia capillaris and Artemisia iwayomogi used as Injin. The antimicrobial activity of the ethylacetate fractions from Artemisia capillaris and Artemisia iwayomogi for tested microbes were stronger than those of ether fractions of the two Artemisia plants. The antimicrobial activity of fractions of Artemisia iwayomogi was higher than that of fractions of Artemisia capillaris for the tested microbes. The extracts of young shoots and leaves showed stronger antimicrobial activity than those of young leaves. The range of minimum inhibitory concentrations(MICs) of ethylacetate fractions from the part of Artemisia capillaris and Artemisia iwayomogi were 0.25~2.0 mg/ml. The MICs of ether fractions were showed higher concentration than those of ethylacetate fractions. The fractions of Artemisia iwayomogi showed lower MICs than fractions of Artemisia capillaris. The highest total polyphenol content was found in young shoots and leaves of A. capillaris. The young shoots and leaves of the two kinds of Artemisia plants showed higher content of total polyphenol.

In this study, the antioxidative activity of Artemisia capillaris T. extract on the proliferation and differentiation of MC3T3-E1 cells under $H_2O_2$-induced oxidative stress was investigated in order to determine its protective effect against oxidative stress as well as its availability as an antioxidant material related to treatment of bone diseases. As a result, the total polyphenol content of A. capillaris extract was 90.10 mg/g, whereas the flavonoid content was 4.45 mg/g. A. capillaris extract increased proliferation of MC3T3-E1 cells under $H_2O_2$-induced oxidative stress, and also increased the proliferation of differentiated osteoblast cells under oxidative stress. In addition, two differentiation markers, alkaline phosphatase activity and mineralization level, in A. capillaris extract tended to increase. These results indicate that A. capillaris extract suppresses the damage to osteoblasts caused by oxidative stress, which demonstrates its availability as an antioxidant material for preventing bone diseases.

The composition of essential oils isolated from the aerial parts of Artemisia iwayomogi Kitamura and Artemisia capillaris Thunberg collected from two diffenent cultivation area, respectively, was analyzed by GC and GC-MS. Sixty components were identified in oils from A. iwayomogi. The major components of A. iwayomogi oil collected from one area (Sample A) were iso-pinocamphone (31.64%), 1,8-cineo1e (21.55%), ${\beta}-pinene$ (4.46%), pinocarvone (3.72%), myrtenal (3.42%) and trans-pinocarve1 (3.14%), and the major components of the oil from the other area (Sample B) were camphor (26.99%), 1,8-cineo1e (21.55%), ${\alpha}-terpineol$ (7.63%), borneol (4.10%), camphene (3.97%) and artemisia ketone (3.84%). Eighty components were identified in oils from A. capillaris. The major components were capillene $(26.01{\sim}30.31%)$, ${\beta}-pinene(8.55{\sim}18.38%)$, ${\beta}-caryophyllene(8.80{\sim}13.70%)$, ${\beta}-himachalene(1.67{\sim}5.57%)$, $cis,trans- {\alpha}-farnesene(2.10{\sim}7.38%)$ and germacrene D $(2.27{\sim}5.46%)$ and there was no difference in oil composition of A. capillaris between two cultivation area.

This study analyzes the apoptosis of HeLa cells to see if we can use the Artemisia capillaris Thunberg for the prevention of chronic degenerative diseases. We used the HeLa cells to see what effects the A. capillaris Thunberg had on apoptosis of the cancer cells. We checked the cell activity, cell morphological change, DNA fragmentation, and DNA content after administering 0, 100, 500, 1000, and $2000{\mu}g/ml$ methanol, ethyl acetate, n-butanol extract of the A. capillaris Thunberg. As for the cell viability, the increase of concentration of methanol and ethyl acetate decreased the survival rate of the cell, but the phenomenon was much weakened in n-butanol extract and was not observed in aqueous extract. The higher the density of the methanol, ethyl acetate, n-butanol and aqueous extract was, the lower the survival rate of the HeLa cell was. These extracts obstructed the cell cohesion and caused the blebbing of he cell membrane and fragmentation of the nucleus, both of which are symptoms of apoptosis. Laddering-pattern DNA fragmentation was observed in the groups that were treated with the $1000{\mu}g/ml$ and $2000{\mu}g/ml$ of methanol extract. The DNA content of the cells apoptosis measured by fluorescent-activated cell sorter (FACS) increased as the density of the methanol, ethyl acetate and butanol extract increased. The result of the study shows that A. capillaris Thunberg fosters the apoptosis of HeLa cells, which suggests that the A. capillaris Thunberg has a great potential value as food additives, medicinal supplements for patients with chronic diseases, and preventive measures against cancer.

The effect of extraction methods, such as reflux extraction (RE), autoclave extraction (AE), low temperature high pressure extraction (LTPE) and ultrasonification extraction (USE) on antioxidant activity of various species of Artemisia (Artemisia capillaris T., Artemisia princeps P., Artemisia annua L.) was investigated. The extraction yield of RE and AE was higher than other methods tested for all Artemisia. The total polyphenol and flavonoid content of Artemisia sp. extracts from RE was highest of the extraction methods tested. The total polyphenol and flavonoid content of A. capillaris T. extracted by RE was 260.82 mg GAE/g and 11.52 mg RHE/g, respectively. The A. capillaris T. extract showed higher DPPH and ABTS radical scavenging activity than that of the other tested Artemisia sp. Nitrite scavenging activity and superoxide dismutase (SOD)-like activity of various extracts from RE was 45.48% and 68.29% (A. capillaris T.), 45.73% and 61.43% (A. princeps P.), and 44.25% and 58.19% (A. annua L.), respectively. The RE method was the most effective method for extracting antioxidant substances from various A. capillaris T. compared with AE, LTPE and USE. These results suggest that extracts of Artemisia sp. from RE can be used as bioactive and functional materials in the food industry.

The purposes of this dissertation were to examine relativity between growth characteristics factors and develop the model of growth characteristics. In the result of statistical summaries of the factors in growth characteristic, the highest level of correlation was in plant height, plant width, petiole and chlorophyll in the case of Artemisia iwayomogi; leaf length, in the case of A. stolonifera;, leaf width, of A. princeps var. orientalis;, diameter, of A. feddei;, leaf thickness, of A. iwayomogi, A. princeps var. orientalis, A. montana, A. stolonifera, A. sylnatica; leaf length and leaf width of the other species. In the case of correlation analysis, leaf width and diameter were most correlative in A. capillaris;, plant height and plant width, in A. montana; plant height and leaf width, in A. stolonifera; leaf length and leaf width, in other species. The results of model analysis of growth characteristics were as follows. A. capillaris proved to be about $79.4\%$ effective ; A. princeps var. orientalis, about $91.7\%$ ; A. montana, about $70.3\%$ ; A. iwayomogi, about $49.0\%$ ; A. stolonifera, about $72.5\%$; A. sylnatica, about $75.0\%$;, A. feddei about $60.4\%$ ; A. rubripes about $54.0\%$.
