The hot water and mathanol extracts of Artemisia argyi showed considerable cytotoxicities against H9(ATCC HTB 176) cancer cell with IC50 values of $48.6{\;}\mu\textrm{g}/ml$ and $51.9{\;}\mu\textrm{g}/ml$, respectively. These cytotoxicities were found to be dependent on the extract concentrations and culture days. CuZnSOD and MnSOD activities were significantly increased in the cytoplasm and mitochondria fractions of cancer cell, and media in the presence of Artemisia argyi. Such enhanced SOD activities were generally in the range of two to threefolds. In contrast to SOD, catalase and glutathione peroxidase activities were not detected at all. These results suggest that Artemisia argyi have generated $O_2^-$ in the mitochondria and cytoplasm of H9 cancer cell with concurrent induction of CuZnSOD and MnSOD in situ, which dismutate $O_2^-{\}to{\;}H_2O_2$. Without coordinated actions of catalase and/or glutathione peroxidase $H_2O_2$ is easily converted to very toxic OH and these reactive oxygen species together might have induced necrosis and/or apoptosis of H9 cell.

Several herbs including Artemisia are known to possess conceptive property. In the present study, mouse spermatozoa were incubated with ethanol extract of Artemisia vulgaris leaves. The effect of extract on acrosome exocytosis was studied by labeling spermatozoa with fluorescein isothiocyanate (FITC) peanut agglutinin and by staining with Coomassie blue. Viability and membrane integrity were studied by Trypan-blue staining and hypo-osmotic swelling test. Artemisia extract at very low concentration caused precocious acrosome reaction and loss of sperm viability. Acrosome reaction increased remarkably from 22.63% to 88.42% with increasing extract concentration from 0 to 2,000 ㎍/mL. However, the viability loss of spermatozoa was increased from 11.71% in control to 63.73% in samples treated, evaluated by Trypan-blue staining method. Membrane damage caused by the extract, evaluated by hypo-osmotic swelling test was even low, ranging from 2.27% to only 24.23%. These results indicate that Artemisia extract might block fertilization by causing precocious acrosome exocytosis in spermatozoa. A direct contraceptive effect was tested by injecting the plant extract into the vagina of female mice and then allowing them to mate with normal males. The treated female mice delivered significantly fewer litters in comparison to the control.

The aim of this study was to investigate the effect of plant growth at several different growing periods on antioxidant activities and zeatin and ABA contents of Artemisia iwayomogi. Measurements of antioxidant activities, lipid peroxidation inhibition, and superoxide radical scavenging activity were done using PMS, NBT and lipid auto-oxidation analysis, respectively. The results show that activities of antioxidants from Artemisia iwayomogi had much higher than BHT. DPPH free radical scavenging effect of Artemisia leaf extract was increased from $71.06{\pm}4.36%$ in April to $90.06{\pm}4.41%$ in October. Activities of superoxide radical scavenging and lipid peroxidation inhibition were $33.83{\pm}3.45%$ and $45.60{\pm}3.10$ in April and then increased to $84.40{\pm}4.00%$ and $75.86{\pm}3.50%$ in October, respectively. An ELISA technique has been developed for the determination of zeatin and ABA in Artemisia leaves. By this method, the content changes of zeatin and ABA from Artemisia during the growth were investigated. The zeatin content in leaf was measured to be $186.86{\pm}1.40$ pmol/g dry weight in April, however, decreased to $117.93{\pm}5.83$ pmol in October. The ABA content in leaf increased from $19.00{\pm}1.26$ nmol in April to $68.20{\pm}2.52$ nmol in October. Relationship between antioxidant activities and plant hormone contents was indicated that antioxidant activity may depend on decreasing zeatin content or increasing ABA content.

This study was conducted to identify allelopathic effect of Ganghwa domestic Artemisia spp., named Sajabalssuk and Ssajuarissuk, for various receptor plants including clover (Trifolium repens L.), alfalfa (Medicago sativa L.), lawn grass (Zoysia japonica Steud.), dandelion (Taraxacum platycarpum Dahlst.), and dahurianpatrinia (Patrinia scabiosaefolia Fisch. ex Trevir). Receptor plants were treated with the aqueous and essential oil extract of Artemisia plants. In consequence, their allelopathic effects were evaluated by measuring seed germination rates, seedling growth, and dry weights of the receptor plants. The seed germination and seedling growth of the receptor plants were inhibited by all treatments of both aqueous and essential oil extracts of the Artemisia plants, and, in addition, the inhibitory effects were increased according to the higher concentration. Among the donor plants, A. $sp.^*III$ showed most effective allelopathic effect. Comparing the alleopathic effect among the receptor plants, seed germination was most inhibited in lawn grass while inhibitory effect of seedling growth was comparatively higher in dandelion. Although inhibitory effects were comparatively lower, the allelopathic effects of Artemisia plants were identified in clover and alfalfa since the seedling growth of these plants were inhibited more than 70%. Thus, in result, Ganghwa domestic Artemisia spp. could be possibly used for weed control since natural products of the plants showed inhibitory effects on seed germination and seedling growth of various receptor plants.

Artemisia capillaris Thunb. is widely used in the herbal medicine field. This study describes the antidepressant effect of a flavonoid (chlorogenic acid) isolated from the Artemisia capillaris Thunb. The expression of the pituitary gland and hypothalamic POMC mRNA or plasma ${\beta}$-endorphin levels were increased by extract of Artemisia capillaris Thunb. or its flavoniod administered orally. In addition, antidepressant activity was studied using the tail suspension test (TST), the forced swimming test (FST) and the rotarod test in a chronically restrained immobilization stress group in mice. After restraint stress (2 h/day for 14 days), animals were kept in a cage for 14 days without any further stress, but with drugs. Mice were fed with a diet supplemented for 14 days and during the behavioral test period with chlorogenic acid (30 mg/kg/day). POMC mRNA or the plasma ${\beta}$-endorphin level was increased by the extract of Artemisia capillaris Thunb. and its flavoniod. In addition, the immobility time in TST and FST was significantly reduced by chlorogenic acid. In the rotarod test, the riding time remained similar to that of the control group at 15 rpm. Our results suggest that the flavonoid (chlorogenic acid) isolated from Artemisia capillaris Thunb. shows a potent antidepressant effect.

BACKGROUND: Currently, natural products have been shown to exhibit interesting biological and pharmacological activities and are used as chemotherapeutic agents. The purpose of this study, conducted on Wistar rats, was to evaluate the beneficial effects of Artemisia arborescens oil on oestroprogestative treatment induced damage on liver. MATERIALS/METHODS: A total of 36 Wistar rats were divided into 4 groups; a control group (n = 9), a group of rats who received oestroprogestative treatment by intraperitoneal injection (n = 9), a group pre-treated with Artemisia arborescens then injected with oestroprogestative treatment (n = 9), and a group pre-treated with Artemisia arborescens (n = 9). To minimize the handling stress, animals from each group were sacrificed rapidly by decapitation. Blood serum was obtained by centrifugation and the livers were removed, cleaned of fat, and stored at $-80^{\circ}C$ until use. RESULTS: In the current study, oestroprogestative poisoning resulted in oxidative stress, which was demonstrated by 1) a significant increase of lipid peroxidation level in hepatic tissue 2) increased levels of serum transaminases (aspartate amino transferase and serum alanine amino transferase), alkaline phosphatase, glycemia and triglycerides and a decrease in the level of cholesterol 3) alteration of hepatic architecture. Pre-administration of Artemisia arborescens oil was found to alleviate oestroprogestative treatment induced damage by lowering lipid peroxidation level and by increasing activity of catalase, superoxide-dismutase, and glutathione-peroxidase in liver and by reducing disruption of biochemical parameters. CONCLUSION: Therefore, the results obtained in this study confirmed that Artemisia essential oil protects against oestroprogestative administration induced hepatotoxicity by restoration of liver activities.

Background and objective: Artemisia argyi has a long history as an effective treatment for various diseases. The detection of environmental pollutant benzo(a)pyrene, a known human carcinogen, in the leaves of Artemisia argyi is cause for concern. For medicinal plant extracts, both a reduction of benzo(a)pyrene as well as the maintained effectiveness of the compound are important. Therefore, in this study, we propose an optimized process for the addition and filtration of activated carbon to reduce benzo(a)pyrene and change the contents of the indicating substance(jaceosidine and eupatilin). Methods: Artemisia argyi EtOH extract containing 36 ppb of benzo(a)pyrene was added to 0.1, 0.5, 1.0, and 1.5% (w/w) of activated carbon for 120 min and filtered using an activated carbon filter 1, 2, 3, and 5 times respectively. The content of benzo(a)pyrene and indicating substances in Artemisia argyi extract were then measured with high performance liquid chromatography (fluorescence and UV detectors). Results: As the amounts of activated carbon powder and filtering cycles increased, the content of benzo(a)pyrene in the Artemisia argyi extract decreased. However, when activated carbon powder 1.5% was added to the extract, and when the activated carbon filter was filtered five times, the results were reduced by 15% and 30~40% respectively. The optimal extraction condition for reducing benzo(a)pyrene was adding 1.5% of activated carbon powder. This resulted in reducing benzo(a)pyrene by 83% and indicating substances by about 4%. Conclusions: Here we present a process for reducing benzo(a)pyrene in Artemisia argyi extract using activated carbon to reduce toxicity and minimize the loss of active ingredients. This approach has potential application within a manufacturing process of various medicinal plant extracts.
