To examine the effect of Artemisia princeps var orientalis on cardiovascular system, cadiovascular response from its water extracts were studied in the atria and aortae of normal rats. The extracts diminished spontaneous beat and contractile force in the left and right atria, and caused the relaxation of thoraic aortae. As for the blood pressure, the mugwort extract had a descending effect.

식품으로 사용하면서 약용식물인 참죽나무 잎, 미나리 및 쑥의 methanol엑스를 실험재료로 하여, 생쥐를 이용한 항염증 및 진통작용을 관찰하였다. 쑥은 부종 및 혈관투과성항진모델에 대해 유의한 항염증활성을 나타내었으며, 진통작용에서는 3종류 식물들의 유의한 진통활성이 관찰되었다.

The profile and concentration of monoterpene metabolites in the leaf and stem of Artemisia princeps var. orientalis were quantified, and seasonal variation in monoterpenes of Artemisia plant was investigated. Samples were taken from five sites at the campus of Kyungnam University during maturing season. Monoterpenes in leaf and stem were analyzed using gas chromatography-mass spectrometry (GC-MS). The major constituents of A. princeps var. orientalis in both the leaf and stem were 21 monoterpenes.$ {\alpha}-pinene,\;{\beta}-pinene,\;{\beta}-myrcene$, dl-limonene, naphthalene and unknown monoterpenes with 5.49 and 16.27 of retenstion time were present in high concentrations of compounds identified on the leaf and stem of A. princeps var. orientalis. The cmounts of total monoterpenes of leaf were from two to five times higher than stem and rapidly decreased with the time, while that of stem was constnat except early spring. Most of the high percentage of monoterpenes in the leaf were those with later retention time. These results indicated that monoterpenes yields are considered to be more variable than monoterpene composition in responding to the time in both the leaf and stem.

Leaves from natural populations of Artemisia princeps var. orientalis in Suncheon of South Korea were examined for antimicrobial and antioxidative activities monthly (April through October). The antimicrobial activity of the ethyl acetate and water fractions of crude methanol extract from the plant collected monthly against three gram-positive, two gram-negative and one lactic acid bacteria were studied. The ethyl acetate and water fractions of crude methanol extract from A. princeps var. orientalis collected in August and September had the highest antimicrobial activity. Minimum inhibitory concentrations (MIC) for each strain by ethyl acetate fraction of methanol extract from A. princeps var. orientalis was different depending on strains and sampling months. MIC for each strain was the highest in the sample of April, followed by October. In specific, MIC for Bacillus cereus was around 0.25mg/disc in the sample of April. The MIC for Staphyllococcus aureus was 0.01mg/disc in the sample of July, August, and September. It was the lowest value among tested strains and samples. And the antimicrobial activity for Lactobacillus plantarum was not found at any concentrations and sampling months. The in vitro antioxidative activities of methanol extract from Artemisia princeps var. orientalis collected monthly were determined by the scavenging of DPPH radical and inhibition of xanthine oxidase activity. The DPPH scavenging activity of the extracts from the plant sampled in May, June and July were higher than any other months. The xanthine oxidase activity of the extract of A. princeps var. orientalis collected in April and May showed the greatest activity, it is different with antimicrobial activity.

Artemisia princes var. orientalis의 수용성 추출물이 식품, 화장품, 의약품 등의 항균제로 이용될 수 있는지에 대해 연구 하였다. 순수한 물을 이용한 추출물에서는 항균성을 찾기 힘들었고, 쑥의 줄기와 잎 부분에서 메탄올로 추출한 후 물로 추출한 물이 Staphylococcus aureus에 대해서 항균성을 크게 나타냈으며, 잎이 줄기 부분보다 더 큰 항균성을 나타냄을 확인했다. 항균성을 갖는 물질을 밝혀내기 위해 쑥의 주된 항균 성분이라 알려진 caffeic acid와 비교 실험을 하였다. UV 특성곡선에서 caffeic acid와 유사한 phenolic compound의 profiling은 확인할 수 있었으나 caffeic acid의 disc diffusion method를 이용한 실험에서는 항균능력을 나타내지 않았다. 물질규명을 위해 추출물을 세 부분으로 분획 하였고, 이 중에서 Staphylococcus aureus에 대해 항균성은 UK 2에서 크게 나타났다. 본 연구는 Artemisia princeps var. orientalis 의 메탄올 후 물 추출물이 항균제로써의 가능성을 알아봄으로써 식품 또는 화장품의 보존료나 항균제의 이용성이 있음을 충분히 확인하였다.

The effects of Artemisia princeps var orientalis(mugwort), Circium japonicum var ussuriense(Unggungqui) on serum lipid componets in rats was evaluated. Thirty rats divided into 5 experimental groups were fed with the diet containing 1% cholesterol, 0.25% sodium cholate, 10% coconut oil and 5% lard(control diet), supplemetned with 5% plant powder or its water soluble extract(experimental diet) for 4 weeks. Proximate analysis data and compositions of ash, dietary fiber and fatty acids in plants were presented. The concentrations of the total cholesterol was significantly lower in Ungungqui powder, Ungungqui extract and mugwort powder diet groups than the control. Serum HDL-cholesterol level was significantly higher in Unggunqui powder and Unggunqui extract diet group than the control. The concentration of LDL was significantly lower in Unggungqui power or extract diet group compared to the control. The values of VLDL and chylomicron were comparatively lower in Unggungqui power and mugwort powder diet group than in the other diet groups. The concentration of seum triglyceride and phospholipid was lower in Unggungqui powder diet group than in the control.

The effects of Artemisia princeps var orientalis(mugwort), Circium japonicum var ussuriense (Unggungqui) on cadiovascular system in hyperlipidemic rats were investgated. Thirty rats devided into 5 experimental groups, were fed with the diet contained 1% chlesterol, 0.25% sodium cholate, 10% coconut oil and 5% lard by the same method of previous paper1). Contractile and relaxation responses in the isolated artria and thoracic aortae were measured and the morphological changes of the aortic endotherium from the rats were inspected. The responses of the right atrial to isoproterenol were significantly lower value in Ungungqui powder diet group(UP) and mugwort powder diet group(MP) than the control. The contraction force by injectin of phenylephrine and calcium in isolated thoracic aortae was significantly low value in the UP and the MP groups compaired to the control. The relaxation rate by acetylcholine in isolated thoracic aortae represented significantly higher value in UP than control. The morphological changes of endothelial cell suface was smallest in UP and the damage of endothelium by retarded in MP. Although Ungungqui and mugwort extract diet groups(UE, ME) were advanced, those were less than control.

The effect of Artemisia princeps var orientalis(mugwort) and Circium japonicum var ussuriense (Unggungqui) on lipid metabolism was examined . Thirty rats of 5 experimental groups were fed with a diet containing 1% cholesterol and 0.25% sodium cholate(control diet) and 5% plant powder or its water soluble extract(experimental diet) for 4 weeks. The activity of enzymes related to liver function, lipid components of liver and principle organs, and fecal steroids were assayed. The activity of enzymes was significantly lower in the unggungqui and mugwort powder diet group than in control. Liver total cholesterol , free cholesterol, and triglyceride levels were significantly lower in Unggungqui powder diet groups that in the control. The concentrations of total cholesterol , triglyceride and phospholipid in heart and kidney were comparatively low in the Unggungqui powder diet groups. In each plant powder diet group, the values of serum bile acid were significantly lowe ran the fecal steroid excretion was higher than in the control and the extract diet groups.

어병 세균에 대해 쑥(Artemisia princeps var. orientalis) 추출물인 정유의 항균성을 조사하였다. Aeromonas hydrophila, Aeromonas salmonicida, Aeromonas sorbia, Edwardsiella tarda 와 Streptococcus sp. (yellowtail)는 1,000~2,000 ppm 에서 증식이 억제되었다. 즉 억제 농도는 A.salmonicida 가 1,000 ppm A.hydrophila, A. sorbia, E. tarda 와 Streptococcus sp. (yellowtail)는 1,500 ppm 이었다. 그러나 Vibrio anguillarum, Vibrio ordalii, Edwardsiella ictaluri와 Streptococcus sp. (SF-1)는 100~2,000 ppm 농도에서 현저한 억제 효과는 없었다.
