  • 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 capillaris THUNB is a perennial herb that belongs to the family Compositae spp and the most common plant among the various herbal folk remedies used in treatment of abdominal pain, hepatitis, chronic liver disease, jaundice and coughing in Korea. In this study, antimicrobial effects of Artemisia capillaris extracts on the food poisoning bacteria were investigated for further clinical application, which is an alternative for the use of antibiotics and their unexpected resistance. Artemisia capillaris extract using ethyl acetate showed the highest antimicrobial effects on S. enteritidis, E. coli O157 : H7, L. monocytogenes and S. aureus. The chloroform extract showed strong effects on all kinds of bacteria; whereas ethanol and methanol extracts showed weaker effects. Finally, ether and water extracts showed the weakest effects under the same conditions. The minimum inhibitory concentration (MIC) of ethyl acetate extract was 1 mg/mL for E. coli O157 : H7 and L. monocytogenes, and 2 mg/mL for S. enteritidis and S. aureus. The inhibitory effects on all the bacteria continued for 12 hours after incubation using 20 mg/mL and 30 mg/mL of ethyl acetate extract. The inhibitory effects continued maximally for 72 hours. The results of these studies indicate Artemisia capillaris extract exhibited excellent antimicrobial and inhibitory effects on the food poisoning pathogenic bacteria; S. enteritidis, E. coli O157 : H7, L. monocytogenes and S. aureus.

  • Freezing and drought tolerances in plants are very important for survival in the desert. In an effort to reduce desertifcation in Gobi, a molecular breeding of Artemisia adamsii using the CLP (chitinase like protein, antifreeze protein) and Dhn5 (dehydrin5) genes from barley is performed by introducing them into Artemisia adamsii via Agrobacteria. We had found an optimal combinatorial concentration of hormones at 0.05mg/L of NAA and 0.5mg/L of BA for growth of callus in Artemisia adamsii. In addition, the higher rate of callus induction using hypocotyl as explant was observed comparing to explants of stem and leaf. There were some variations in the level of the proteins expressed among the transgenic lines such that the lines of CLP(CS1-5, 1-7,4-4) and Dhn5(DS2-2, 2-3) lines produce the protein to higher levels. The transgenic lines showing a higher level of Dhn5 exhibited better growth than nontransgenic callus in presence of 10 and 20% PEG. In case of the CLP tansgenic lines, both CS1-5 and CS1-7 showed a higher level of freezing tolerance determined by ion leakage test.

  • 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.

  • This study was intended to investigate the capitulum morphology and to evaluate its taxonomic importance within the 23 taxa of Korean Artemisia L. The Korean Artemisia was classified into sterile subg. Dracunculus and fertile subg. Artemisia by the fertility of the disk florets, which is the traditional diagnostic character of subgenera. There are sections in subg. Artemisia: sect. Absinthium with a densely, sparsely hairy receptacle, and sect. Abrotanum and sect. Artemisia with a glabrous receptacle. However, A. fukudo and A. sacrorum belonging to sect. Abrotanum, and A. viridissima belonging to sect. Artemisia were observed to have sparsely hairy receptacles. Therefore, the presence of hair on a receptacle, which is now regarded as a key character distinguishing sections, has to be reevaluated. The whole shape and size of the capitulum, the characteristic of the stigma apex, the hair on the involucral bract, and the shape of the central or peripheral floret are thought to be the most valuable characters to consider in recognizing species.

  • We examined dyeing properties using cotton, Tencel, general nylon 66 and hollow nylon 66 treated with aqueous and ethanol extracts without mordant. The antimicrobial properties of fabrics treated with Artemisia extracts against gram positive Staphylococcus aureus (S. aureus) and gram negative Klebsiella pneumonia (K. pneumonia) were also examined. The dying solution concentrations were determined from a calibration curve of the concentration and absorbance of Artemisia extracts. FTIR spectra confirmed that antimicrobial components and colorants (such as 1,8-cineol, thujone, caffeoylquinic acid and chlorophyll) were more present in ethanol extract than in aqueous extract. Nylons had higher $a^*$ and $b^*$, and lower $L^*$ values than cellulose fabrics dyed with aqueous solutions of Artemisia extracts; however, the dyed nylon fabrics were brown. Fabrics dyed with ethanol-extract added solutions were greener and had higher antimicrobial properties than those dyed with aqueous solutions; however, they faded and lost their antimicrobial properties after laundering. Fabrics regained their antimicrobial properties (especially against S. aureus) by the spraying of Artemisia ethanol extract; therefore, the application of Artemisia ethanol extract onto underwear is expected to relieve atopic dermatitis.

  • This study was designed to investigate the effect of Artemisia capillaris extracts on the intestinal microflora. In agar diffusion method, the solvent fractions of Artemisia capillaris showed growth inhibition against the intestinal microflora. In particular, the chloroform fraction of Artemisia capillaris had strong antibacterial activity against Clostridium perfringens, Clostridium difficile, Eubacterium limosum, and Bacteroides fragilis, but did not show antibacterial activity against Bifidobacterium bifidum and Lactobacillus acidophilus. Most chloroform fraction of Artemisia capillaris inhibitory activities were not reduced by heat treatment or pH variation against C. perfringens, C. difficile, E. limosum, and B. fragilis. MICs of the chloroform fraction were 1.25 mg/mL against C. perfringens, E. limosum and B. fragilis and 2.5 mg/mL against C. difficile. MBCs of chloroform fraction were 5 mg/mL against C. perfringens, E. limosum and 2.5 mg/mL against C. difficile, B. fragilis. The ethyl acetate fraction of Artemisia capillaris showed $3.08{\pm}0.03$ mg/10 mg total polyphenol and $1.91{\pm}0.03$ mg/10 mg total flavonoid contents. In vivo tests were performed to investigate the influence of Artemisia capillaris extract on the intestinal microflora in rats. The results showed the possibilities of utilizing Artemisia capillaris extracts as a functional food component to control intestinal microflora.
