Objectives: This study was camed out to examine the effect of five fractions of aqueous extract from Artemisia capillaris THUNB(ACT), on TGF, 1-induced apoptosis, cell viability, cell cycle progression and mRNA expression of apoptosis-related genes in human hepatocyte cell line HepG2. Methods: This study employed Tryphan blue exclusion assay, DNA fragmentation assay, Cpp32 protease activity assay and Quantitative RT-PCR analysis. Results: In the Tryphan blue exclusion assay, the butanol fraction of ACT with $TGF{\beta}$, l showed magnificent (Nice word, ut is it appropriate in a medical abstract\ulcorner) viability and the H2O fraction of ACT with $TGF{\beta}$, l also showed higher viability than only $TGF{\beta}$, l-treated group. DNA fragmentation assay showed that the butanol fraction and the H2O fraction carried inhibitory effects on apoptosis induction, with the butanol fraction displaying greater effects. The Cpp32 protease activity assay showed that the butanol fraction decreased Cpp32 protease activity. The H2O fraction of ACT had no significant effect on the Cpp32 protease activity. Quantitative RT-PCR showed that the butanol fraction suppressed Bax, p 15/INK4B, p21/Waf1, PAI-1 and increased Bcl-2 gene. Conclusions: The data shows that butanol fraction of ACT increases the hepatocyte viability and has the hepatocellular protective effect by the suppression of $TGF{\beta}$, l induced-apoptosis through gene regulation.

The objective of this study was to investigate the biological activities of fermented mugworts and their effects on the lipid metabolism in hyperlipidemia-induced rats. The proximate compositions of two kinds of mugwort, Artemisia capillaris Thumberg and Artemisiae asiaticae Nakai, were compared before and after fermentation. In both types of mugwort crude protein and amino nitrogen contents markedly increased with fermentation. Thrombolytic activity determined from the size of the clear zone on a fibrin plate was higher for the Artemisiae asiaticae Nakai, especially in the fermented sample. Antioxidative activity according to DPPH(1,1-diphenyl-2-picrylhydrazyl) radical scavenging effects was higher for Artemisia capillaris Thumberg but no significant differences were found between the samples after fermentation. The body weights of hyperlipidemia-induced rats that were fed the mugworts for 4 weeks were lower than those of the control group. In all the mugwort-fed rats serum total cholesterol and LDL-cholesterol levels remarkably decreased. Furthermore the fermented mugworts were found to be more effective at decreasing triglyceride (TG) levels. It is also noteworthy that the highest HDL-cholesterol levels were observed in the rats treated with the fermented Artemisiae asiaticae Nakai. And fatty liver weights were higher in the rats fed Artemisia capillaris Thumberg. In conclusion the feeding of fermented Artemisiae asiaticae Nakai was effective for increasing thrombolytic activity and HDL-cholesterol levels as well as reducing TG levels in rats.

Artemisia iwayomogi (Compositae), a perennial mugwort, is native to Korea and widely distributed in Japan, Russia, and China. A. iwayomogi and A. capillaris are similar in morphology and pharmacological activity and have been used for the same medicinal purposes in Korea. While various ingredients such as coumarins and flavonoids and their activity studies have been reported for A. capillaris, few studies have been conducted on the pharmacologically active components of A. iwayomogi. In Korea, A. capillaris is not economical because only young leaves are used as a medicinal material. Because of this, A. iwayomogi is frequently used in Korea, indicating the need to study its pharmacologically active components. Therefore, a phytochemical study was initiated to isolate active compounds from the aerial parts of A. iwayomogi. Finally, four coumarins, umbelliferone (1), esculetin (2), grevillone (3), and scoparone (4) were isolated for the first time from the aerial parts of A. iwayomogi in this study.

This experiment was conducted to investigate antitumor and immunomodulatory effects of Artemisia capillaris extracts against Hepa-lc1c7 and Sarcoma 180 cancer cells. In in vivo experimental tests using 210 ICR mice, on the $28^{th}$ day and the $42^{nd}$ day, all animals in vehicle controled HP (Hepa-lclc7 tumor cell inoculated vehicle control) and SP (Sarcoma 180 tumor cell inoculated vehicle control) showed tumor cells in the liver and spleen based on the histopathology. However, the incidences and the percentages of regions occupied by tumor cells were dramatically and dose-dependently decreased by mACH (Artemisia capillaris methanol extracts) treatment on the histomorphometry. Although the exact mechanism of inhibition of the incidences of tumor cells in the parenchyma whether inhibition of metastasis or proliferation is unclear, mACH dramatically reduce the percentages of regions occupied by tumor cells in the liver and spleen apart from the inoculation sites of Hepa-lclc7 and Sarcoma 180. In addition, they also effectively inhibit the abnormal changes on the kidney detected in the present study. The results suggest that Artemisia capillaris methanol extracts have prominent antitumor effects on the cancer cell lines Hepa-lclc7 and Sarcoma 180 m mice.

The Artemisia capillaris THUNB is a perennial herb that belongs to the family Compositae spp and probably the most common plant among the various herbal folk remedies being used in the treatment of abdominal pain, hepatitis, chronic liver disease, jaundice and coughing in Korea. Recently the biological and pharmacological actions of herb have been studied well such as antibacterial, antidiabetic and antitumor activities. This experiment was conducted to investigate antitumor and immunomodulatory effects of Artemisia capillaris extracts against Hepa-1c1c7 and Sarcoma 180 cancer cells in in vivo experimental tests. In in vivo experimental tests using 210 ICR mice, based on flow cytometry, CD3+, CD4+, CD8+ and TNF-${\alpha}+$ splenocytes were significantly (p<0.05) reduced in the Hepa-1c1c7 and Sarcoma 180 inoculated vehicle controls, HP and SP, compared to those of the intact vehicle control on both the $28^{th}$ day and the $42^{nd}$ day, respectively. These decreases of CD3+, CD4+, CD8+ and TNF-${\alpha}+$ cells induced by tumor inoculations were significantly (p<0.05) inhibited by mACH treatment regardless of the type of experiments and tumor cells inoculated. The results suggest that Artemisia capillaris methanol extracts have prominent antitumor effects on the cancer cell lines Hepa-1c1c7 and Sarcoma 180.

The immune activation and anticancer activities of the water and ethanol extracts from Artemisia capillaris Thunb. were studied. The growth of human hepatocarcinoma and human gastric cancer cell was inhibited by the addition of $1.0\;mg/m{\ell}$ of the water extract, by about 77% and 95%, respectively. The growth of human breast cancer cells was also inhibited by addition of $0.5\;mg/m{\ell}$ of both water and ethanol extracts by 88%. The growth of human normal lung cell, HEL299 was inhibited by 15% indicating very low cytotoxicity of both extracts. Overall selectivity of the both extracts on several human cancer cell line was over 2.5. The growth of both human B and T cells was enhanced up to 1.6 to 2.1 times by adding the ethanol extracts. The secretion of cytokines, $TNF-{\alpha}$ and IL-6, from human B cells was also increased showing $68\;pg/m{\ell}$ and $67\;pg/m{\ell}$, respectively, compared to $35{\sim}40\;pg/m{\ell}$ of the control. In terms of the immune activity, there was not much difference between water and ethanol extracts of Artemisia capillaris Thunb. It implies that the extraction solvent could not differ the biological activities of the extracts. Based on these results, Artemisia capillaris Thunb. can be developed into a potentially useful cancer chemoprentive agent.

The antioxidant activities of 6 solvent extracts of Artemisia capillaris were evaluated in a dintroflurobenzen (DNFB)-induced allergic mouse model. In vitro antioxidant activities were determined using DPPH and the FRAP test. Methanol (DPPH: 85.87%, FRAP: 1.772) and $dH_2O$ (DPPH: 60.69%, FRAP: 3.185) extracts showed the highest antioxidant activities compared with other solvents (ethyl acetate 41.81%, 0.407, hexane 8.37%, 0.328, etc.). In addition, we tested atopic dermatitis (AD)-like skin lesions in mice treated with DNFB. The methanol extract of A. capillaris on the AD-like skin lesions in DNFB-induced atopy inhibited ear thickness increases (47%) and the skin lesions (45%) compared with a positive control (methanol). The results suggest that they have potential as natural antioxidants and allergy-improving substances and that they may be valuable materials in the functional food or cosmeceutical industry.

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.

In order to examine antioxidative characteristics of Artemisia capillaris response surface methodology was used to optimize the hot water extraction process by analyzing and monitoring the extraction condition. For total phenolic compounds content, the optimal extraction temperature, time and amount of solvent per sample were $94.50^{\circ}C$, 2.06 hr and 25.03 ml/g, respectively. Also, the optimal conditions for electronic donating ability were $91.82^{\circ}C$, 2.90 hr and 20.88 ml/g, respectively. The nitrile scavenging ability (pH 1.2) was optimized using the extraction temperature of $97.36^{\circ}C$, extraction time 2.75 hr and 15.19 ml/g as the amount of solvent per sample. Regression equations of total phenolic compounds content, electron donating ability and nitrile scavenging ability as dependent variable were deduced from each analyzed extraction condition. And finally, their response surfaces were superimposed with the optimal conditions to obtain values for each extraction process factor. The predicted results through superimposing were extraction temperature $90{\sim}95^{\circ}C$, extraction time 2.5~3.5 hr and amount of solvent per sample 17~24 ml/g.
