  • 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.

  • The purpose of this study is to investigate effects of several zinc solutions including Artemisia asiatica-containing zinc solution on concentration of oral volatile sulfur compounds(VSCs). We determined the VSCs concentration of breath of human subjects before and after use of zinc solutions(O.25% $ZnF_2$ Artemisia asiatica-containing 0.25% $ZnCl_2$ and Artemisia asiatica-containing 0.25% $ZnCl_2$ solutions) The results were as follows : 1. 0.25% $ZnCl_2$ solution was more effective than 0.25% $ZnF_2$ solution in reducing the concentration of oral VSCs and the maintenance duration of effectiveness. 2. Artemisia asiatica-containing 0.25% $ZnCl_2$ solution was more effective than Artemisia asiatica-containing 0.25% $ZnF_2$ solution in reducing the concentration of oral VSCs and the maintenance duration of effectiveness. 3. Artemisia asiatica-containing 0.25% $ZnF_2$ solution and 0.25% $ZnF_2$ solution showed no significant difference in reducing the concentration of oral VSCs and the maintenance duration of effectiveness but, Artemisia asiatica-containing 0.25% $ZnF_2$ solution was slightly more effective. 4. Artemisia asiatica-containing 0.25% $ZnCl_2$ solution and 0.25% $ZnCl_2$ solution showed no significant difference in reducing the concentration of oral VSCs and the maintenance duration of effectiveness but, Artemisia asiatica-containing 0.25% $ZnF_2$ solution was slightly more effective.

  • The purpose of this study was performed to evaluate antioxidant activity of the Artemisia asiatica Nakai and Moringa oleifera Lam mixture extract. Mixture extracts were manufactured by concentration and compared with a single extract (only the Artemisia asiatica Nakai mixture and only the Moringa oleifera Lam mixture). The experiments conducted Total polyphenol measurements, Total flavonoid measurements, DPPH radical scavenging activty, ABTS radical scavenging activty and LDH assay. The LDH assay assessment shows that all extracts are cells compared to controls. The toxicity was weak. Finally, The antioxidant capacity was rated higher than mixture extract of a single extract. Also, the optimized mixture was determined AM5 (Artemisia asiatica Nakai mixture: Moringa oleifera Lam mixture = 3:1). For extracts of AM5, Total phenol and flavonoid contents were 271.769±18.087 mg/g and 45.384±5.026 mg/g. and DPPH and ABTS scavenging activity were 70.8±6.496% and 77.1±9.634%. Therefore, it is expected that the value of the extract will increase as it increases its antioxidant activity if it is manufactured according to the appropriate ratio.

  • Ethanol ($70\%$) extract of Caesalpinia sappan L. and Forsythiae suspensa Vahl. showed $84\%$ and $72\%$ of anti-urease activity against Helicobacter pylori, respectively. Among the fraction of Artemisia asiatica Nakai extract using methanol ($80\%$), water, ethyl acetate and butanol ethyl acetate fraction showed $90\%$ of the anti-urease activity.

  • Bone resorption surrounding tooth root causes tooth loss in periodontitis patients. Osteoclast has bone resorption activity. Effects of Artemisia asiatica on bone resorption induced by periodontopathogens, Porphyromonas gingivalis and Treponema denticola, were examined using co-culture systems of mouse osteoblasts and bone marrow cells. Addition of A. asiatica ethanol extract to bacterial sonicate abolished bacteria-induced osteoclastogenesis. To determine inhibitory mechanism of A. asiatica against osteoclastogenesis, effects of A. asiatica on expressions of osteoclastogenesis-inducing factors such as receptor activator of NF-${\kappa}B$ ligand (RANKL), prostaglandin $E_2\;(PGE_2)$, interleukin (IL)-1, and tumor necrosis factor (TNF)-${\alpha}$, in osteoblasts were examined. A. asiatica suppressed expressions of RANKL, $PGE_2$, IL-$1{\beta}$, and TNF-${\alpha}$ increased by each bacterial sonicate. These results suggest inhibitory action of A. asiatica against osteoclastogenesis is associated with down-regulations of RANKL, $PGE_2$ IL-$1{\beta}$, and TNF-${\alpha}$ expressions.

  • In this study, liquid with carbonized artemisia was developed for the first time that can be used as food additives and outside medicinal agents by burning artemisia species such as Artemisia dubia wall, Artemisia capillaris Thunb, Artemisia montana (Nakai) Pamp), Artemisia keiskeana Miq, Leonurus Japonicus Houtt. etc. In addition, edibility of recovered liquid with carbonized artemisia was verified by comparing the contents according to each ingredient with common refined pyroligneous liquid through the analysis of 9 kinds of organic acid by the species of artemisia, methanol and ethanol. Besides, the result of antimicrobial activities on six kinds of food spoilage and food poisoning bacteria observed by paper disc method for liquid with carbonized artemisia indicated that those two liquids showed strong antimicrobial. At the concentration of 1.5 mg/disc, clear zone for S. sonnei and S. aureus, L. monocytogenes was 13~16 mm, and they showed stronger antimicrobial activities than other strain.

  • It has long teen known in herbal medicine that the mugwort not only exerts a strong hemostatic and parasiticidal actions but also has therapeutic effects for stomachache and diarrhea. In recent pharmaceutical botany the mugwort is known to have antipyretic and astringent actions also. Among the major principles which have been found in the leaves and stems of mugwort are inulin, alkaloids, vitamines, and esestial oil. It is well known that santonin, one of the well known parasiticides, is one of the glucosides extracted from the limited species of mugwort. The present study was undertaken to investigate effects of mugwort(Artemisia asiatica Nakai) on the motility of isolated rabbit duodenum. The results obtained are as follows: At does of 0.2%, 0.5% and 1. 0% AAJ(Artemisia asiatica juice) markedly enhanced contractility of isolated duodenum and tonus of the intestine was also augmented with doses of 0.5% and 1.0%. The augmentative effect of AAJ on intestinal motility was not affected by pretreatment with epinephrine and avil while it was completely abolished by atropine. Therefore it is strongly suggested that augmentative action of AAJ on duodenal motility was exerted solely through muscarinic cholinergic receptors.

  • 본 연구는 들깨와 쑥 잎의 휘발성 타감작용을 확인하고, 그 성분을 동정하려 한 것이다. 휘발성분을 벼, 무우, 녹두, 상치를 대상으로 생물검정하여 휘발성 타감작용을 확인했다. 휘발성분을 headspace cold trapping-Tenax GC 흡착으로 분리하여 들깻잎으로부터 terpenoid 4종, aldehyde 3종, alcohol 3종, 탄화수소류 3종, 기타 성분 1종을 동정하였으며, 쑥으로부터는 terpenoid 9종, aldehyde 3종, alcohol 1종, 기타 성분 1종을 검출하였다. 한편, 수증기 증류-추출로 포집한 경우에는, 들깻잎으로부터 terpenoid 2종, alcohol 2종의 동정되었으며, 쑥 잎으로부터는 terpenoid 6종, alcohol 1종, 탄화수소류 1종, 기타 성분 2종이 검출되었다. 수증기 증류-추출로부터 나누어진 각 분획을 무우를 대상으로 생물검정한 결과 중성 분획이 가장 타감작용 활성이 컸다. 휘발성 타감작용 성분을 분리하기 위해 이를 GC-MS로 분석한 결과, 들깨로부터 terpenoid 7종과 alcohol 2종 등 9종을 동정하였고, 쑥으로부터 terpenoid 15종과 alcohol 3종, aldehyde 1종, 탄화수소류 2종, 기타 성분 3종 등 24종을 동정하였다.
