Artemisia iwayomogi, a member of the Compositae, is a perennial herb easily found in Korea and used as a traditional medicine to treat liver disease. AIP1, a water-soluble carbohydrate fraction from Artemisia iwayomogi, showed anti-tumor and immuno-modulating activities in animal studies. A subacute toxicological evaluation of AIP1 was performed for 4 weeks in ICR mice. After administration of AIP1 (0, 20, 100, 500 mg/kg/day), the clinical signs, mortalities, body weight changes, hematology, blood clinical biochemistry, urinalysis, organ histopathology, organ weights and gross finding were examined. The results showed that there were no significant differences in body weight changes, food intakes, water consumptions, or organ weights among different dose groups. Also we observed no death and abnormal clinical signs during the experimental period. Between the groups orally treated with AIP1 and the control group, there was no statistical significance in hematological test or serum biochemical values. Histopathological examination showed no abnormal changes in AIP1 groups. These results suggest that no observed adverse effect level (NOAEL) of the oral administration of AIP1 for 4 weeks was considered to be more than 500 mg/kg/day in mice under the condition investigated in current study.

This study aims to examine the antibacterial effects of cotton and silk fabrics naturally dyed with Artemisia princeps extract on antibiotic-resistant strains of bacteria. The concentrated natural dye of the Artemisia princeps extract was made at the liquor ratio of 1:10 at 40-60℃ for 60 minutes. The concentration of FeSO4·7H2O, Al2(SO4)3, and CuSO4 5H2O mordant was 3% (owf), and the liquor ratio was 1:20. In order to experiment on the antimicrobial activity of the naturally dyed fabrics, Methicillin-resistant Staphylococcus aureus (MRSA) ATCC 33591, was used by breeding it in Brain Heart Infusion Agar (BHA) containing Oxacillin (2㎍/ml), Fungizone (2.5㎍/ml), and Brain Heart Infusion broth (BHI; Detroit, MI, USA). As a result of examining the bacterial growth reduction rate on dyed cotton and silk fabrics against antibiotic-resistant strains, it was found that the copper mordant in cotton fabric shows the highest antibacterial activity with a bacterial growth reduction rate of 99.9%, and the non-mordant cotton fabric shows the lowest antibacterial activity with a reduction rate of 18.6%. In the case of the naturally dyed silk fabric, it indicates the highest reduction rate of strains in the Al mordanting (94.9%), and Cu mordanting (99.9%).

Artemisia princeps PAMPANINI has been used in traditional medicine of the treatment of inflammatory, liver dysfunction and order disorder in the far east countries including Korea. The present study was carried out to investigate the hepatoprotective effects of ethanol extract of Artemisia princeps (AP) and its fermented agents (AP-F) by lactic acid bacteria derived from human intestinal bacteria on liver injured rat induced by $CCl_4$ and d-galactosamine. Hepatoprotective activity was monitored by estimating serum ALT, AST, ALP, LDH, superoxide dismutase (SOD), glutathione redeuctase (GR) and glutathione peroxidase (Gpx) activities in the liver injured by hepatotoxin. Pretreating rats with AP or AP-F at the same dosage regimen significantly suppressed the acute elevation of serum transaminase, ALP, LDH and GR activities, and significantly increased the lowering of blood SOD and GR activites induced by hepatoxin. Based on these findings, it is presumed that AP and APF may have the hepatoprotective effect on $CCl_4$ and d-galactosamine-induced hepatotoxicity rat.

As obesity is known to be related to hyperlipidemia, insulin and leptin resistance, and other chronic diseases, much recent research has focused on functional food materials and their anti-obesity activity. This study was performed to study the effects of Artemisia Iwayomogi oligosaccharide AIPI on the anti-obesity function in normal rats and diet-induced obese (DIO) rats. F344 male rats were divided into four groups: Normal-control (CONT), normal-AIPI, DIO-CONT and DIO-AIPI. The groups were provided with water (in the CONT groups) or another drink for 4 weeks. The final body weights of rats in the DIO-AIPI group were lower than those in the CONT group. Abdominal adipose tissue weight per kg of body weight in the DIO-AIPI group was significantly lower than that in the DIO-CONT group. Also, the final levels of serum-triglyceride, serum-total cholesterol and serum-low density lipoprotein cholesterol in the DIO-AIPI group were lower than those in the DIO-CONT group. Moreover, the serum-high density lipoprotein cholesterol level in the normal-AIPI group was significantly higher than that in the normal-CONT group. Finally, the serum-leptin concentration was significantly lower in the DIO-AIPI group. Total lipid, triglyceride, and total cholesterol contents in the feces of the DIO-AIPI group were as high as 142％, 199％, and 165% of the respective values of the DIO-CONT GROUP. These results indicate that orally administered Artemisia Iwayomogi oligosaccharide not only has hypotriglycemic and hypocholesterolemic effects, but also has the effect of reducing the body weight and the abdominal adipose tissue weights obese rats. Therefore, we expect that Artemisia Iwayomogi oligosaccharide AIPI may have an anti-obesity function in F344 diet-induced obese rats. (Korean J Nutrition 36(5): 437∼445, 2003)

The experiment was carried out to find the effects of transplanting time and vinyl-film mulching treatment on the growth of artemisia by randomized block design with three replications. The experiment site ($100{\times}130$ m) was temporally established in the south-eastern part of Saemangeum reclaimed tidal land (near Gwanghwal myun, Gimjae-gun, Jellabukdo). Artemisia plants had been partly suffered from salt injury, because soil salinities in some area during growing period had been measured higher than 10 dS $m^{-1}$. Growth of plant height and survival ratio of transplanted plants had been significantly correlated with soil salinity and then the regression equations between plant height (y) and soil EC (x) and between survival ratio (y) and soil EC (x) were expressed as y=-16.59ln(x)+43.852 and $y=0.6453x^2-17.566x+103.99$, respectively. It was concluded that early transplanting and vinyl mulching was more beneficial for biomass production of artemisia, because biomass was 6.41 times more in the early transplanting than in the late transplanting, and 2.63 times more in the vinyl-film mulching than in the no mulching treatment.

Characteristic stereostructures of farnesyl protein transferase (FPTase) inhibition materials isolated from Artemisia sylvatica and regioselectivity of biogenic Diels-Alder reactions between dehydromatricarin molecules A and B were examined quantitatively. Results revealed that the major reaction of frontier molecular orbital (FMO) interaction proceeds through charge-control reaction between LUMO of A16, dienophile and HOMO of B1, diene, and the isolated 8-acetylarteminolide and artanomaloide were minor products. FPTase inhibition activity and hydrophobicity of 8-acetylarteminolide were $pI_{50}=3.75$ and logP=2.62, respectively. FPTase inhibition activity of 8-acetylarteminolide was higher than those of artanomaloide and dehydromatricarin.

In this study, Artemisia mongolica fischer extract was examined for its possible differential inhibitory activity against pathogenic bacteria including Staphylococcus aureus and Lactobacillus spp. isolated from women's vagina. First, seven lactobacillus spp. were selected based on their in vitro high anti-staphylococcal activity. Various samples extracted using different concentrations of organic solvents (acetone, ethanol, methanol) were examined for optimal anti-staphylococal activity. When the Artemisia extract obtained using $100\%$ solvents was added to the cell suspension at $17\%$ (vol/vol), Lactobacillus sp. KLB 224 maintained its viability for 48 hr, whereas S. aureus was completely inactivated showing differential antimicrobial activity of the extract. Using scanning electron microscopy the effect of the extract on the cell morphology was observed: S. aureus showed markedly distorted cell morphology while Lactobacillus sp. KLB 224 appeared to remain intact.
