This study investigated the anti-bacterial and anti-inflammatory activities of Artemisia iwayomogi Kitamura for medical and food additive applications. A 70% methanol extract of A. iwayomogi Kitam. was fractionated with a series of solvents in order of increasing polarity; these fractionated extracts showed high 2,2-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) scavenging activity in the ethyl acetate fractions and high 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity in both the ethyl acetate and chloroform fractions. Levels of total phenolics and flavonoids were highest in the ethyl acetate fraction extracts. Eight bacteria were then treated with the A. iwayomogi Kitam. extract fractions and most showed similar or lower levels of anti-bacterial activity when compared to the control group, except for Staphylococcus aureus. In addition, the anti-oxidant activities of the ethyl acetate fractions of the A. iwayomogi Kitam. extract were higher than those of the other fractions. To confirm the anti-inflammatory activity of the extract fractions, we applied them to RAW 264.7 cells using LPS, and the results indicate that an ethyl acetate fraction at 250 ㎍/ml concentration inhibits nitric oxide production. This study demonstrates that an ethyl acetate fraction of A. iwayomogi Kitam. extract inhibits bacterial and inflammatory activities and could be useful as a potential source of bioactive compounds.

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.

Artemisia messes-schmidiana var viridis(Compositae) has been used for jaundice, hepatitis, diuretic and liver cirrhosis etc. 1-naphthylisothiocyanate(ANIT) has been used as a model compound to study mechanisms of intrahepatic cholestasis in laboratory animals as rat and mouse. The purposes of present study are to examine pharmacological effects of Artemisia messes-schmidiana var viridis water extract(AMWE) on alterations of triacylglycerol, cholesterol, protein, albumin and A/G ratio levels in serum, of histopathological appearances of liver, and that of hepatic microsomal cytochrome P-450 contents. Increased serum triacylglycerol levels by ANIT were significantly decreased with AMWE. However, AMWE posttreatment aggravated ANIT-induced cholesterol increase. Serum total protein and albumin contents, and A/G ratio were decreased in all ANIT-treated groups, and there were increased compared with control by AMWE posttreatment. Hepatic microsomal cytochrome P-450 contents were decreased in either AMWE and ANIT treatment, which greatly increased with AMWE pretreatment. On the other hand, in histological findings, our results shown that ANIT induced increase of lipid droplets and widening of sinusoidal capillary and these phenomena were disappeared with AMWE treatment. In conclusion, AMWE have choleresis effect. Also, AMWE improved lipid metabolism, protection and regeneration of hepatocytes in ANIT-induced cholestasis.

This study was performed to compare anticancer and immune activities between natural Artemisia capillaris Thunb. extract and tissue cultured plant extract (hairy root, in vitro culture, callus). The inhibitory effect of cancer cell growth, human B cell growth and productivity of cytokines were examined. Furthermore, HPLC analysis was performed to confirm the components. The anticancer activities increased by more than 55% with the cultured callus of Artemisia capillaris T. for four cancer cell lines(Lung carcunoma, Stomach adenocarcinoma, Hepatocillular carcinoma, Breast adenocarcinoma), showing higher effect than natural Artemisia capillaris T. The extracts from hairy root and in vitro culture of Artemisia capillaris T. significantly increased the immune B cell growth. The immune B cell growth effect of natural Artemisia capillaris T. was higher than that of the tissue culture plants such as hairy root, in vitro culture and callus. Both natural and tissue cultured plants showed similar effects on cytokine secretion. The similar peak size was observed between natural Artemisia capillaris T. and cultured callus in HPLC analysis. As a results, the biological activities were not observed the difference between natural Artemisia capillaris T. and cultured callus. Thus, the cultured callus will be altered natural Artemisia capillaris T. in the environmental side and the resources preservative side

In oriental medicine, 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 lwayomogi water extract(AIWE) on weights of body, liver, kidney, spleen and adrenal, and on biochemical parameters (activities of AST, ALT and LDH, contents of cholesterol and triacylglycerol, and levels of hepatic lipid peroxide) against hepatic injury by carbon tetrachloride($CCl_4$) in rats. The results were as follow; 1. Body weights were reduced by $CCl_4$. In AIWE pretreatment groups, reduction of body weights was inhibited at 48 hours. Increased liver weights by $CCl_4$ were reduced in proportion to numbers of treatment of AIWE in AIWE pre- and posttreatment groups. Increased kidney weights by $CCl_4$ were reduced in AIWE pretreatment groups at 72 hours. Increased weights of spleen and adrenal by $CCl_4$ were not affected by AIWE treament. 2. Increased AST activities by $CCl_4$ were significantly (p<0.05) decreased in AIWE posttreatment groups at 48 and 72 hours. Increased ALT activities by $CCl_4$ were significantly(p<0.05) decreased in AIWE posttreatment groups at 48 hours. Increased LDH activities by $CCl_4$ were very significantly (p<0.01, p<0.001) decreased in AIWE posttreatment groups at 48 and 72 hours, respectively. 3. Increased cholesterol contents by $CCl_4$ were significantly (p<0.05) decreased in AIWE posttreatment groups at 24 and 48 hours. Decreased triacylglycerol contents by $CCl_4$ were significantly (p<0.05) increased in AIWE posttreatment at 48 and 72 hours. 4. Increased hepatic lipid peroxide levels by $CCl_4$ were significantly (p<0.05, p<0.01) decreased in AIWE posttreatment groups at 48 and 72 hours, respectively. In conclusion, AIWE did not affect normal liver function and had property of antioxidant, due to reduced lipid peroxidation by $CCl_4$. AIWE seems to have hepatoprotective effects rather than direct preventive effects to $CCl_4$-induced necrotic degeneration of liver cell, cholestasis and damages in metabolism of lipid.

Antioxidant and cancer cell growth inhibition activity of hot water extract from five different varieties of Artemisia (A. Argyi H., A. iwayomogi Kitamura, A. Princeps Var Orien talis HARA, A. princeps Pampanini and A. annua L.) in Korea was studied. We determined the phenol and flavonoid contents and examined antioxidant assay, such as DPPH, NO radical scavenging, activity ferric-reducing antioxidant power (FRAP), and bleaching inhibition activity in the ${\beta}$-carotene linolic acid system. Also, we performed HeLa and MCF-7 cancer cell growth inhibition assay of Artemisia extracts. Total phenol and flavonoid contents were the highest in A. iwayomogi Kitamura followed by A. Argyi H. DPPH radical scavenging activity was the highest in A. Argyi H. at 50 ${\mu}g/ml$ concentration, NO radical scavenging activity was more than 50% in A. Princeps Var Orien talis HARA, A. princeps Pampanini, and A. annua L. at 200 ${\mu}g/ml$ concentration. FRAP was higher in A. Argyi H. and A. iwayomogi Kitamura. Antioxidant activity in the ${\beta}$-carotene linolinolic system was also higher in A. Argyi H. and A. iwayomogi Kitamura by 60.50% and 56.90% at 100 ${\mu}g/ml$ concentration, respectively. In cancer cell growth inhibition activities at 400 ${\mu}g/ml$ concentration, A. iwayomogi Kitamura showed greater than 80% on HeLa cell. A. princeps Pampanini and A. Argyi H. extract had growth inhibition activities greater than 80% on MCF cell. The results of this study suggest that the antioxidant and anticancer activities in various Artemisia are a promising source of functional food ingredients.
