Artemisia princeps has been utilized as a traditional medicine for a variety of diseases in Korea. In this study, we investigated the effects of Artemisia princeps extract (APE) on bone metabolism both in vitro using primary mouse bone marrow-derived macrophage and in vivo using ovariectomized rats. APE decreased the number of tartrate-resistant acid phosphatase (TRAP)-positive multinucleated cells and TRAP activity. Also, APE inhibited bone resorptive activity of differentiated osteoclasts. In ovariectomized rats, APE alleviated the decrease in the trabecular bone mineral density. These results showed that APE might be useful for the prevention of postmenopausal bone loss.

This study investigated the antioxidative effect of mugwort (Artemisia vulgaris L.) extracts in hairless mouse skin from oxidative stress induced by UV-irradiation. After topical application on hairless mouse back with basic skin lotion group (control), ascorbic acid group (AA-0.5%, AA-1.0%, AA-2.0%, and AA-5.0%), and mugwort extract group (ME-0.5%, ME-1.0%, ME-2.0%, and ME-5.0%), the animals were irradiated to increasing doses of UVB (60 $mJ{\sim}100$ mJ) for 4 weeks. Hydrogen peroxide of hairless mouse skin homogenate significantly decreased in 2% (p<0.05) and 5% (p<0.05) of ME and AA groups. Hydroxyl radicals were decreased significantly in both of 2% and 5% ME groups as compared to AA groups (p<0.05). Oxidative stress levels deduced by oxidized protein contents were greatly decreased ($14.6{\sim}18.5%$) in all ME treatment groups, while only at 2% of AA treatment group. Lipid peroxide contents were greatly inhibited in all ME and AA treatment groups (p<0.01). Application of ME significantly increased catalase activity, over 25% in all mugwort and AA groups. Glutathione peroxidase activities were increased up to $20.5%{\sim}32.8%$ in 2.0% and 5% ME groups, whereas it increased in all AA groups. These results suggested that mugwort extract was more effective than that of ascorbic acid in protecting hairless mouse skin from photo-irradiation, and can be used as an potential anti-aging cosmetic ingredients.

The feeding effects of mugwort (Artemisia vulgaris L.) extracts (ME) on the anti-oxidative actions of ICR mouse skin was investigated. To study the antioxidative effects of ME on ICR mouse skin, female ICR mice were grouped into basic diet group (control), ascorbic acid diet group (AA-2.5, AA-5.0, AA-10.0 and AA-20.0 mg/kg BW/day) as a positive control and experimental diet group (mugwort extract; ME-25, ME-50, ME-100, and ME-200 mg/kg BW/day) and fed for 10 weeks. Protein contents in ME-50, ME-100, and ME-200 feeding group were increased ($3.1%{\sim}11.1%$) and hydroxyl radical contents were significantly decreased ($10.4%{\sim}17.4%$) compared to control group. Oxidative stress signals and oxidized protein contents were significantly reduced to the range of 15.3 to 17.1% in ME-100 and ME-200 groups. Also, superoxide dismutase (SOD) activity was significantly increased to the range of 15.0% to 23.3% in ME-100 and ME-200 groups. Catalase activities were significantly increased ($14.0%{\sim}36.9%$) in all groups in a dose-dependent pattern. Antioxidative ability of ME showed similarity to that of ascorbic acid.

This study was done to investigate the protective effects of ethanol extract Artemisiae vulgaris L(Av) on carbon tetrachloride(CCl₄)intoxicated rats. Male sprague Dawley rats(200~210g)was used. experimental groups were divided into normal group, CCl₄-control group, and ethanol extract CCl₄-treated group. CCl₄-treated groups were injected with CCl₄ 0.6mg/kg.b.w(i.p). The activities of Alanine aminotransferase(ALT), Aspartate aminotransferase(AST), Alkaline phosphatase(ALP), Glutamyl transpeptidase(γ-GT), Lactate dehydrogenase(LDH) in extract pretrated group was significantly decreased(p<0.05) compared to the CCl₄-control group. The contents of triglyceride, cholesterol and lipid peroxide were significantly decreased(p<0.05). whereas the contents of HDL-cholesterol and glutathione(GSH) were significantly increased(p<0.05). These results suggest that extract of Artemisiae vulgaris L(Av) has hepatoprotective effect in the CCl₄-intoxicated rats.

This study used response surface methodology (RSM) in an effort to optimize the ultrasoundassisted extraction condition of Camellia sinensis L. and Artemisia argyi mixture in order to increase extraction yield in the extract. The effects of three independent variables, $X_1$ (Mixture ratio, 60-80%), $X_2$ (Ratio of water to raw material, 20~100 mL/g), and $X_3$ (Extraction time, 25-145 min), were investigated at three levels using Box-Behnken design (BBD) to obtain the highest extraction efficiency. Y (Extraction yield) was chosen as dependent variable. Our result showed that the coefficient of determination ($R^2$) of the model was 0.9747, with significant at the level of p < 0.002. Furthermore, the predicted values of each variable were similar to the actual values. The optimum extraction conditions were as follows: mixture ratio of 85.86%, ratio of water to raw material of 92.73 mL/g, and extraction time of 56.52 min. At these conditions, predicted extraction yield was 30.03%. The analysis of variance (ANOVA) indicated a high goodness of model fit and the success of the RSM method for optimizing extraction conditions of Camellia sinensis L. and Artemisia argyi mixture.

Artemisia asiatica Nakai aqua-acupuncture solution (ANAS) was administered once daily for 10 days before the tumor implantation ($1{\times}10^6\;cells$). Body weight, spleen weight and the number of ascitic tumor cells were measured at 6 days after tumor implantation. The change of body weight and the survival rate of mice were observed for 21 days. It was used three biomarkers (quinone reductase, glutathione, glutathione S-transferase) to test chemopreventive potentials of ANAS. ANAS exerted antitumor activity by inhibiting the growth of Ehrlich ascites tumor cells in vivo. Mice given Ehrlich cells and ANAS at $CV_{12}$ and $BL_{18}$ had 57.1% to 49.2% survival after 21 days. Quinone reductase activity and glutathione levels were increased with ANAS. However, glutathione S-transferase level was 1.1-fold with ANAS. These results suggest that ANAS has chemopreventive potential by inducing QR activity and increasing GSH level.

This study was to investigate antiwrinkle effect of mugwort (Artemisia vulgaris) methanol extract in hairless mouse skin induced by UVB-irradiation. Hairless mouse were topically treated with the basic lotion alone (control), ascorbic acid (AA-0.5%, AA-1.0%, AA-2.0%, and AA-5.0%) and mugwort extract (ME-0.5%, ME-1.0%, ME-2.0%, and ME-5.0%) dissolved in a basic lotion. After topical treatment of 30 minutes, the animals were irradiated with increasing doses of UVB radiation ($60{\sim}100\;mJ/cm^2$) for 4 weeks. In our experimental condition, skin thickness of hairless mouse was significantly decreased ($12.5{\sim}21.4%$) in all ME groups compared with control group. Ra value, that is surface roughness parameter induced by skin wrinkling, was significantly decreased ($23.7{\sim}31.1%$) in ME-1.0%, 2.0% and 5.0% group compared with control group. Furthermore, Rq, Rz and Rt value were significantly decreased to $11.2{\sim}21.2%$, $19.8%{\sim}24.5%$, and $14.2%{\sim}22.7%$, respectively. Wrinkle formation of ascorbic acid treatment group as reference group was inhibited, but its effect was less than ME treatment. Matrix metalloproteinase-1 activity was significantly inhibited ($19.7{\sim}22.6%$) compared with control group and collagen content was significantly increased (about 10%) when compared with control group. These results indicate that ME could protect skin aging and wrinkle formation in hairless mouse from photo-irradiation.
