Objective : This study was carried out to examine the effect of five fractions of an aqueous extract from Artemisia capillaris $T_{HUNB}$. Methods : The queous extract from Artemisia capillaris $T_{HUNB}$. was fractionized into 5 kinds of material. We observed the effect of each fractions on etoposide-induced apoptosis, cell viability, cell cycle progression and mRNA expression of apoptosis-related genes in human hepatocyte cell line HepG2. Results and Conclusions : The data shows that butanol fraction of Artemisia capillaris $T_{HUNB}$. has no relation with cell cycle, however, it inhibits apoptosis significantly and the action may be due to the suppression of Fas and Sax genes and activation of Bcl-2 gene.

We investigated the antimicrobial activity of ether and ethylacetate fractions from Artemisia capillaris and Artemisia iwayomogi used as Injin. The antimicrobial activity of the ethylacetate fractions from Artemisia capillaris and Artemisia iwayomogi for tested microbes were stronger than those of ether fractions of the two Artemisia plants. The antimicrobial activity of fractions of Artemisia iwayomogi was higher than that of fractions of Artemisia capillaris for the tested microbes. The extracts of young shoots and leaves showed stronger antimicrobial activity than those of young leaves. The range of minimum inhibitory concentrations(MICs) of ethylacetate fractions from the part of Artemisia capillaris and Artemisia iwayomogi were 0.25~2.0 mg/ml. The MICs of ether fractions were showed higher concentration than those of ethylacetate fractions. The fractions of Artemisia iwayomogi showed lower MICs than fractions of Artemisia capillaris. The highest total polyphenol content was found in young shoots and leaves of A. capillaris. The young shoots and leaves of the two kinds of Artemisia plants showed higher content of total polyphenol.

The effect of extraction methods, such as reflux extraction (RE), autoclave extraction (AE), low temperature high pressure extraction (LTPE) and ultrasonification extraction (USE) on antioxidant activity of various species of Artemisia (Artemisia capillaris T., Artemisia princeps P., Artemisia annua L.) was investigated. The extraction yield of RE and AE was higher than other methods tested for all Artemisia. The total polyphenol and flavonoid content of Artemisia sp. extracts from RE was highest of the extraction methods tested. The total polyphenol and flavonoid content of A. capillaris T. extracted by RE was 260.82 mg GAE/g and 11.52 mg RHE/g, respectively. The A. capillaris T. extract showed higher DPPH and ABTS radical scavenging activity than that of the other tested Artemisia sp. Nitrite scavenging activity and superoxide dismutase (SOD)-like activity of various extracts from RE was 45.48% and 68.29% (A. capillaris T.), 45.73% and 61.43% (A. princeps P.), and 44.25% and 58.19% (A. annua L.), respectively. The RE method was the most effective method for extracting antioxidant substances from various A. capillaris T. compared with AE, LTPE and USE. These results suggest that extracts of Artemisia sp. from RE can be used as bioactive and functional materials in the food industry.

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

The antioxidant activities of Artemisia capillaris and Artemisia iwayomogi used as Injin (Korean herbal name) were investigated. The DPPH radical scavenging activity of the ethylacetate fractions obtained from the Artemisia capillaris and Artemisia iwayomogi was higher than other fractions. No DPPH radical scavenging activity was observed in hexane frcations. The nitrite scavenging activity was the highest at pH 1.2, and the peroxide value for linoleic acid was increased during the incubation.

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.

Artemisia capillaris Thunb. (Compositae) is a traditional medicinal plant with various pharmacological activities. To elucidate new anti-allergic and anti-inflammatory constituents, the aerial parts of A. capillaries were investigated to afford a new compound, (6E,8E)-6-methylundeca-6,8-diene-2,5,10-trione (17) together with 19 known compounds (1 - 16, 18 - 20). The structures of these compounds were determined by extensive spectroscopic analyses including 1D, 2D NMR, HREIMS, and optical rotation [α]_D. The absolute configuration of compound 2 was determined to be S form for the first time. All isolates (1 - 20) were tested their inhibitory effects on interleukin 2 (IL-2) expression in T cells and NO production in lipopolysaccharide (LPS)-stimulated RAW246.7. Among them, compounds 10, 11, 19, and 20 reduced IL-2 expression in a dose-dependent manner. In addition, compound 10 also inhibited NO production with an IC₅₀ value of 37.3 ± 0.4 μM.

In this study, the antioxidative activity of Artemisia capillaris T. extract on the proliferation and differentiation of MC3T3-E1 cells under $H_2O_2$-induced oxidative stress was investigated in order to determine its protective effect against oxidative stress as well as its availability as an antioxidant material related to treatment of bone diseases. As a result, the total polyphenol content of A. capillaris extract was 90.10 mg/g, whereas the flavonoid content was 4.45 mg/g. A. capillaris extract increased proliferation of MC3T3-E1 cells under $H_2O_2$-induced oxidative stress, and also increased the proliferation of differentiated osteoblast cells under oxidative stress. In addition, two differentiation markers, alkaline phosphatase activity and mineralization level, in A. capillaris extract tended to increase. These results indicate that A. capillaris extract suppresses the damage to osteoblasts caused by oxidative stress, which demonstrates its availability as an antioxidant material for preventing bone diseases.
