  • Microcystis aeruginosa (M. aeruginosa) is a cyanobacterium species that can form harmful algal blooms in freshwater bodies worldwide. The use of Artemisia asiatica extracts to control M. aeruginosa inhibition will be environmentally friendly and promising. Artemisia asiatica extracts removed successfully upto 88% of M. aeruginosa pH 8 at $25^{\circ}C$ of temperature. These results was indicated that the amount of 2.24 g/L Artemisia asiatica extracts was removed 1g dryweight/L of M. aeruginosa. The kinetic data showed substrate inhibition kinetics and maximum growth rate was obtained when the M. aeruginosa was grown in medium containing 2.5 g/L of initial concentration of Artemisia asiatica extracts. In the various growth control models, Luong model showed the highest correlation coefficient of 0.9916. Therefore, the Luong model was the most suitable control model for the growth control of M. aruginosa using Artemisia asiatica extracts. In conclusion, the growth control of M. aruginosa using Artemisia asiatica extracts can be applied in the field without controlling the temperature and pH of rivers and streams, and it is possible to control the growth of M. aruginosa efficiently in a short time. The natural extract, Artemisia asiatica extracts, can be a promising inhibition due to its high efficiency and low dose requirements.

  • Artemisia iwayomogi has been used in Korea for many centuries as a treatment for anemia. The effect of Artemisia iwayomogi on tracheal smooth muscle is not known. The purpose of the present study is to determine the effect of Artemisia iwayomogi on histamine induced tracheal smooth muscle contraction in guinea pigs. Guinea pigs(500g, male) were killed by CO₂ exposure and a segment (8-10mm) of the thoracic trachea from each rat and guinea pig was cut into equal segments and mounted ‘in pairs’ in a tissue bath. Contractile force was measured with force displacement transducers under 0.5g loading tension. The dose of histamine (His) which evoked 50% of maximal response (ED/sub 50/) was obtained from cumulative dose response curves for histamine (10/sup -7/~10/sup -4/M). Contractions evoked by His (ED/sub 50/) were inhibited significantly by Artemisia iwayomogi. In guinea pig tracheal smooth muscle, the mean percent inhibition of histamine induced contraction was 31.9% (p<0.05) after 100㎕/㎖ Artemisia iwayomogi. L-NNA slightly but significantly attenuated the inhibitory effects of Artemisia iwayomogi. Following treatment with L-NNA, the mean percent inhibition caused by 100㎕/㎖ Artemisia iwayomogi fell to 44.6% in guinea pig induced by histamine contraction. Propranolol, indomethacin and methylene blue did not significantly alter the inhibitory effect of Artemisia iwayomogi. These results indicate that Artemisia iwayomogi can relax histamine induced contraction of guinea pig, and that this inhibition related to nitric oxide formation.

  • 본 연구는 한국산 쑥속 23분류군에 대하여 두상화서의 세부 형질을 조사하여 분류학적 중요도를 파악하고자 하였다. 쑥속의 속내 분류에 있어서 전통적인 아속의 구분형질인 중앙화의 임성 여부에 의해 중앙화가 불임성인 Dracunculus아속과 중앙화가 임성인 Artemisia아속으로 구분되었다. Artemisia아속 내에서 절을 구분하는 형질로 알려진 화탁의 털 유무는 화탁에 털이 밀생하거나, 성기게 나는 Absinthium절과 화탁에 털이 없는 Abrotanum절, Artemisia절과 구분되었다. 그러나 Abrotanum절의 큰비쑥(A. fukudo), 더위지기(A. sacrorum)와 Artemisia절의 외잎쑥(A. viridissima)에서 성기게 털이 있는 화탁이 관찰됨으로, 절의 식별형질로서 인정되는 무모성 화탁의 가치는 재검토되어야 할 것으로 판단되었다. 이외에 관찰된 형질 중 두상화서의 전체 형태와 크기, 주두정단의 특징, 포편의 털, 중앙화와 주변화 화관의 형태 등은 종의 식별로서 가치가 있는 것으로 판단된다.

  • Artemisia capillaries is a major important food and medicinal resource in Korea. In order to confirm the biological activities of Artemisia capillaries, we investigated antioxidant and anticancer activities from in vitro assays. The Artemisia capillaries methanol (MeOH) extracts was used for the evaluation of DPPH scavenging, total phenolic content, total flavonoid content, hydroxyl radical (${\bullet}OH$) scavenging, reducing power assay as antioxidant activity, as well as anticancer activities as MTT assay. As a result, the Artemisia capillaries MeOH extracts showed potent antioxidative activity and anticancer activity in vitro. These results suggest that the Artemisia capillaries MeOH extracts have a potential alleviated oxidation process, cell motility activity, and tumorigenesis.

  • In this study, Artemisia capillaris, which has been used in oriental medicine and folks remedy, was investigated to characterize the nutritional composition (protein, lipid, ash, fiber, amino acids, fatty acids, Na, K, P, Mg, Ca and Fe) and effective substance (scopoletin). Artemisia capillaris has often been cited in medical literature for its medicinal effects. The Korean Food and Drug Administration allowed Artemisia capillaris as a food stuff and indicated as In-Jin-Sook. From the view point of the subjects who eat In-Jin-Sook products, most of them ingested it for a certain pharmacological efficacy rather than as a beverage or a food. Therefore, we need to develop functional foods using In-Jin-Sook. Artemisia capillaris was superior in protein, crude fiber, amino acid and fatty acid compositions to wild greens according to Korean Nutritional Composition Table. Also scopoletin, blown for blood vessel relaxation and hypotensive effect, was detected at the level of 326.13 $\mu\textrm{g}$/g. These results demonstrated that Artemisia capillaris has both pharmaceutical effects and balanced nutritional contents. Artemisia capillaris has sufficient values to use as a food stuff for functional foods.

  • Artemisia capillaris and Artemisia iwayomogi are weeds used as medicinal plants in Korea under the name "Injin". I collected leaves of A. capillaris and A. iwayomogi, examined them for phytotoxic effects from volatile substances and determined the composition of monoterpenes in the leaves. The effects of volatile substances from each species on seed germination and radicle elongation in each of the two Artemisia species were assessed. The volatile substances of A. capillaris did not negatively affect the seed germination of A. capillaris, but they did inhibit radicle elongation. Rates of seed germination of A. iwayomogi decreased when the seeds were exposed to high concentration of A. capillaris volatile substances. The inhibition of seed germination and radicle elongation by volatile substances from both Artemisia species was stronger for A. iwayomogi than for A. capillaris. I identified the monoterpenoids from the leaves with a gas chromatograph-mass spectrometer (GC-MS). The main constituents of A. capillaris were acenaphthylene (37.91%), $\beta$-pinene (12.08%), 4-carene (10.61%) and $\gamma$-curcumene (9.92%), while those of A. iwayomogi were germacrene-$\delta$ (32.15%), borneol (21.24%), camphor (20.45%) and trans-caryophyllene (7.75%).

  • Artemisia capillaris Thunb. (Compositae) is a native herb of East Asian countries and has used for the treatment of jaundice, high liver fever, and digestive diseases for a long time, as well as being developed as the source of herbal preparations until now. The major components from A. capillaris were chlorogenic acid (1) and its derivatives substituted with caffeoyl moieties, such as 3,5-dicaffeoylquinic acid (2) and 4,5-dicaffeoylquinic acid (3), and coumarins, such as scoparone. In the study, four compounds, chlorogenic acid, 3,5-dicaffeoylquinic acid, 4,5-dicaffeoylquinic acid and scoparone (4) in the 70% ethanolic extract of A. capillaris were simultaneously determined by using HPLC-UVD system. This method was validated with the terms of linearity, precious and accuracy according to ICH guidelines. The developed method was successfully applied for the quantitative analysis of Artemisia genus, A. capillaris, A. iwayomogi, A. princeps, and A. argyi, distributed in Korea.

  • Eighteen nuclear probes were used to examine RFLP(restriction fragment length polymorphism) between six species of Artemisia spp. of Korea. Total DNA from six different species of Artemisia was separately cut with three restrict enzymes. The PstI enzyme was showed to reduce the variation of polymorphisms than the other two enzymes(EcoRl and BamHI). The genetic variation of polymorphism was similar between the Dhewegiki-ssug and Cham-ssug. RAPD analysis was applied to the same six species of Artemisia spp. in order to assess the degree of DNA polymorphism within the Artemisia genus. Six species of Artemisia were evaluated for variation using a set of 11 random 10-mer primers. Nine out of the eleven primers revealed scorable polymorphisms between six species of Artemisia spp. Genetic distances between each of the species were calculated and cluster analysis was used to generate a dendrogram showing phylogenetic relationships between them This result indicates that molecular markers will be more usable in intraspecific study of Artemisia spp. than isoenzyme markers.
