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.

Artemisia Iwayomogi Compositae) has been used clinically for jaundice, hepatitis, liver cirrhosis etc. The purposes of present study were to examine pharmacological effects of Artemisia Iwayomogi water extract(AIWE) on biochemical parameters (activities of ALP and LAP, contents of glucose, total bilirubin, total protein and albumin in serum, A/G ratio, and levels of hepatic glycogen) against hepatic injury by carbon tetrachloride($CCl_4$) in rats. The results were as follows ; 1. Increased ALP activities by $CCl_4$ were very significantly(p<0.001) decreased in AIWE posttreatment groups at 72 hours and significantly(p<0.05) decreased in AIWE pretreatment groups at 72 hours. Increased LAP activities by $CCl_4$ were significantly (p<0.05) decreased in AIWE posttreatment groups at 72 hours. A little increased total bilirubin contents by $CCl_4$ were very significantly (p<0.001) decreased in AIWE posttreatment groups at 24, 48 and 72 hours. 2. Increased glucose contents by $CCl_4$ were decreased in AIWE posttreatment groups. Decreased hepatic glycogen levels by $CCl_4$, were significantly (p<0.05) increased in AIWE posttreatment groups at 48 and 72 hours. 3. Decreased total protein contents by $CCl_4$ were significantly (p<0.05) increased in AIWE posttreatment groups at 48, 72 hours. Decreased albumin contents by $CCl_4$ were increased in proportion to numbers of AIWE treatments in AIWE pre- and posttreatement groups. Decreased A/G ratios by $CCl_4$ were significantly (p<0.05) increased in AIWE posttreatment groups at 48 hours. In conclusion, AIWE did not affect normal liver function and had hepatoprotective effects rather than direct preventive effects to $CCl_4$-induced cholestasis, damages in metabolisms of glucose, protein and bilirubin.

Han In-jin (Artemisia iwayomogi Kitamura) and Cham Dang-gwi (Angelica gigas Nakai) exhibit antibacterial, antiparasitic, antifungal, and antiviral properties in vitro. In this study, mixture of the extracts of these two medicinal plants was absorbed on pellets. Thereafter, these pellets were fed to olive flounder Paralichthys olivaceus for 12 weeks at laboratory (1^st experiment) and 24 weeks at field test (2^nd experiment), and the immune activity and disease resistance properties of the extracts were examined. It was observed that lysozyme activities of plasma, spleen, and kidney improved after 12 weeks. Furthermore, when the olive flounders were artificially infected with bacterial pathogens, their cumulative mortality decreased in the group that was fed the extracts for 12 weeks compared to that in control group, and the relative percent survival also improved. This study concluded that mixture of Han In-jin and Cham Dang-gwi extracts provides disease resistance in vivo.

더위지기 및 근연분류군은 분류학적 위치 및 학명에 대하여 많은 이견이 있어왔다. 이에 본 연구는더위지기 및 근연분류군인 털산쑥, 흰산쑥의 외부형태학적 연구를 바탕으로 정확한 학명을 부여하고 분류학적 위치를 재검토하기 위하여 실시되었다. 원기재와 기준표본을 비교 및 분석한 결과, 털산쑥(A. freyniana f. discolor)과 흰산쑥(A. freyniana f. vestita)은 잎에서 털의 분포 양상, 지리적 분포, 체세포염색체 수 및 화분의 자상돌기 기부의 연결 유무 등의 특징에 의해 A. sacrorum var. sacrorum와 A. sacrorum var. incana으로 각각 이명 처리하였으며, A. gmelinii의 학명으로 잘못 사용되어온 더위지기(A. iwayomogi)의 학명은 A. sacrorum그룹과의 형태학적 유사성을 바탕으로 신조합명인 A. sacrorum var. iwayomogi (Kitam.) M. S. Park & G. Y. Chung으로 처리하였다. 또한, 이들의 기재, 도해 및 검색표를 제시하였다.

The dose-response effect of polysaccharide extracts(PS-1) from Artemisia iwayomogi was inves-tigated under various hepatic disease models. Silymarin, DDB and UDCA were used as reference compounds. We found that the maximal effective dose of PS-1 was 100 mg/kg b.wt. in $CCl_4$-induced hepatotoxicity, D-galactosamine-induced hepatitis, in ANIT-induced cholestasis and 300 mg/kg b.wt. in $CCl_4$-induced chronic liver disease, 30 mg/tg b.wt. in chronic bile duct ligation and chronic ethanol fatty liver. These findings suggest that PS-1 fraction protects the hepatocyte against various hepatic injuries, and this fracton might be of therapeutic value.

Water extracts of injinssuk (Artemisia iwayomogi Kitamura) (WE) were obtained from the dried and ground leaves and stems of injinssuk. The WE was further fractionated into crude polysaccharide (C-PS) and nonpolysaccharide fractions (N-PS). The protective activities against the tert-butyl hydro peroxide induced mutangenecity on Escherichia coli PQ37 and reactive oxygen species scavenging activity of the WE, C-PS, and N-PS were studied. The WE obtained from leaves showed a significantly higher inhibitory effect on the mutagenicity than WE from stem. The WE obtained from the leaves having higher crude polysaccharide content but lower content of total carbohydrates had significantly higher antimutagenicity than that from the leaves with lower crude polysaccharide but higher total carbohydrate contents. Further study showed that C-PS fraction showed markedly stronger antimutagenic effect than N-PS. C-PS was also more effective than N-PS for hydroxyl radical scavenging activity, but was similar to N-PS in superoxide radical scavenging activity.

섬애약쑥, 인진쑥, 약쑥, 강화사자발쑥 및 개똥쑥 열수 추출물을 제조한 다음 항산화 및 항암활성을 비교 분석하였다. 5종의 쑥 추출물 중 총 페놀 함량은 인진쑥에서 유의적으로 가장 높았으며, 다음으로 섬애약쑥, 개똥쑥, 약쑥 및 강화사자발쑥 순이었다. 플라보노이드 함량도 인진쑥이 가장 높았고, 섬애약쑥은 인진쑥과 유의차가 없었다. 추출물의 농도를 달리하여 항산화능을 측정한 결과, DPPH 라디칼 소거능은 50 ${\mu}g/ml$ 농도에서 섬애약쑥의 활성이 가장 높았고, NO 라디칼 소거능은 200 ${\mu}g/ml$ 농도에서 약쑥, 강화사자발쑥 및 개똥쑥이 약 50% 이상의 활성을 나타내었으며, 이들 시료간에 유의차는 없었다. FRAP법에 의한 항산화능은 섬애약쑥 및 인진쑥에서 높게 나타났으며, ${\beta}$-carotene 존재 하에서의 항산화능 또한 섬애약쑥 및 인진쑥이 100 ${\mu}g/ml$ 농도에서 50% 이상의 높은 활성을 나타내었다. 400 ${\mu}g/ml$ 농도에서 인체 자궁경부 상피암 세포인 HeLa의 증식억제 활성은 인진쑥이 80% 이상으로 활성이 높았고, 유방암 세포인 MCF-7의 대해서는 강화사자발쑥과 섬애약쑥이 80% 이상의 증식억제 활성을 보였다. 이상의 결과, 쑥 추출물은 높은 항산화 활성과 암세포 증식억제 활성을 나타내었으며, 특히 항산화 활성은 ascorbic acid 이상의 높은 활성을 나타내어 천연 기능성 식품 소재로써 활용 가치가 높을 것으로 생각된다.

Polysaccharides fractions from the leaves of Artemisia selengensis$(ASP_1)$ and Artemisia iwayomogi$(ASP_1)$ were extracted and purified by Sephadex gel filtration and DEAE-Sephadex ion exchange chromatographies. Both $ASP_1$ and $AIP_1$ fractions were tested for their effects on the spleen cell culture in vitro. Both $ASP_1$ and $AIP_1$ fractions allow growth of spleen cells up to 3 months in culture, suggesting the immunoregulatory activities of those polysaccharide fractions. The molecular weights of $ASP_1$ and $ASI_1$ fractions were found to be about 2,500 daltons by Sephadex gel filtration chromatography using standard dextrans. Both $ASP_1$ and $AIP_1$ fractions were composed of glucose, xylose and galactose.

한인진의 용매별 분획물에 관한 항염증, 항균효과를 조사하기 위하여 용매별로 추출하여 그 수율을 조사하여 본 결과, H₂O 층에서는 64.20%로 가장 높은 수율을 나타내었으며, Hexane층(16.05%), Chloroform, Ethyl acetate 층(각각 11.11%)의 순으로 조사되었다. 항산화 활성을 알아보기 위한 DPPH와 ABTs 소거활성을 분석한 결과 Ethyl acetate층에서 각각 12.32 ppm, 7.058 ppm로 가장 높은 소거능을 나타내었고 페놀화합물 및 플라보노이드 함량 분석결과 역시 Ethyl acetate 674.13 mg GA/g, Ethyl acetate 232.5 mg GA/g으로 가장 높게 나타났다. 항균 테스트 결과 황색포도상구균인 Staphylococcus aureus 에서 한인진의 Hexane 층은 모든 농도에서 13-18 mm의 Inhibition zone을 보이며 메탄올 추출물에서 16-10 mm 나타냈고, Chloroform층에서도 1,000 ppm에서 15 mm로 나타났다. 염증세포인 RAW 264.7 세포에서 염증억제효과 및 독성을 확인 한 결과 물층을 제외하고 나머지 분획층에서는 염증유발 물질인 LPS를 처리한 군보다 2-9배 이상 효과를 보이는 것으로 확인되었다. 특히 Ethyl acetate층에서 대조군 보다 9배 이상의 높은 항염증효과를 보였으나 세포독성은 나타나지 않는 것으로 확인되었다.
