The Artemisia princeps (Compositae) has been used in traditional Korean medicine for the treatment of microbial infections and inflammatory diseases. Since A. princeps is generally difficult to be discriminated from A. capillaris, A. caplillaris has been misused in place of A. princeps. To solve this problem, a rapid and nondestructive method for discrimination of A. princeps and A. capillaris samples was developed using near infrared spectroscopy (NIRS) in the present study. A principal component analysis (PCA) and a partial least squares discrimination analysis (PLS-DA) were performed to discriminate two species. As a result, with the use of PLS-DA, A. princeps and A. capillaris were clustered according to their genus. These outcomes indicated that the NIRS could be useful for the discrimination between Artemisia princeps and Artemisia capillaris.

Artemisia capillaris Thunb. (Compositae) is a native herb of East Asian countries and has used for the treatment of jaundice, high liver fever, and digestive diseases for a long time, as well as being developed as the source of herbal preparations until now. The major components from A. capillaris were chlorogenic acid (1) and its derivatives substituted with caffeoyl moieties, such as 3,5-dicaffeoylquinic acid (2) and 4,5-dicaffeoylquinic acid (3), and coumarins, such as scoparone. In the study, four compounds, chlorogenic acid, 3,5-dicaffeoylquinic acid, 4,5-dicaffeoylquinic acid and scoparone (4) in the 70% ethanolic extract of A. capillaris were simultaneously determined by using HPLC-UVD system. This method was validated with the terms of linearity, precious and accuracy according to ICH guidelines. The developed method was successfully applied for the quantitative analysis of Artemisia genus, A. capillaris, A. iwayomogi, A. princeps, and A. argyi, distributed in Korea.

Objectives : The present study investigated effects of Artemisia Capillaris Thunberg ethanol extract(EtOH ext). on lowering lipid, anti-oxidation and concentration of plasma inflammatory mediators using rat fed on high oxidized fat. Methods : We divided fat sprague-dawley rats fed on high oxidized into 4 groups. They were normal group, feed with 100 mg/kg Artemisia Capillaris Thunberg group, feed with 200 mg/kg Artemisia Capillaris Thunberg group and feed with 300 mg/kg Artemisia capilaris Thunberg group. They were administered for 4 weeks. We measured concentration of plasma free fatty acid(FFA), plasma triglyceride, plasma total cholesterol, and plasma low density lipoprotein-cholesterol(LDL-cholesterol), plasma high density lipoprotein-cholesterol(HDL-cholesterol), concentration of liver total cholesterol and liver triglyceride (TG), concentration of plasma thiobarbituric acid reactive substance(TBARS) and liver thiobarbituric acid reactive substance(TBARS), glutathione peroxidase (GSH-Px) activity, superoxide dismutase(SOD) activity and catalase(CAT) activity, plasma nitric oxide(NO), ceruloplasmin and ${\alpha}-glycoprotein$. Results : 1. The Artemisia Capillaris Thunberg EtOH ext. groups showed low concentration of plasma FFA, plasma triglyceride, plasma total cholesterol and plasma LDL-cholesterol compared to control group. However, concentration of plasma HDL-cholesterol was increased in the Artemisia Capillaris Thunberg EtOH ext. groups. 2. Concentration of liver total cholesterol and liver TG showed a significantly decrement in all Artemisia Capillaris Thunberg EtOH ext. groups than that of control group. 3. The Artemisia Capillaris Thunberg EtOH ext. groups showed lower values in concentration of plasma TBARS and liver TBARS than that of control group. The values of GSH-Px activity, SOD activity and CAT activity were increased in the Artemisia Capillaris Thunberg EtOH ext. groups. 4. The values of plasma NO, ceruloplasmin and ${\alpha}-glycoprotein$ were decreased in Artemisia Capillaris Thunberg EtOH ext. groups. Conclusions : Based on the results in this study, the Artemisia Capillaris Thunberg EtOH ext. showed a positive effect in lowering lipid, anti-oxidation and decrement of plasma inflammatory mediators.

This study was carried out to investigate inhibitory effect of extracts from Artemisia capillaris Thumb. on maltase, sucrase, ${\alpha}-amylase$, nonspecific ${\alpha}-glucosidase$, and postprandial hyperglycemia. Methanol extract and organic solvent (n-hexane, ethyl acetate, butanol, aqueous) fractions from the medicinal herb were determined for the inhibitory activities against maltase, sucrase and ${\alpha}-amylase$. The methanol extract from A. capillaris strongly inhibited maltase (57%) and ${\alpha}-glucosidase$ (72%) at the concentration of 100 ${\mu}g/m{\ell}$. Among the four fractions (n-hexane, ethyl acetate, butanol, aqueous) examined, the butanol fraction from A. capillaris showed potent inhibitory effects on maltase (73%), sucrase (33%), and ${\alpha}-amylase$ (75%) at the concentration of 100 ${\mu}g/m{\ell}$. The butanol fraction from Artemisia capillaris also exhibited significant reductions (20%) of blood glucose elevation in mice loaded with maltose. These results suggest that the extract from Artemisia capillaris can be used as a new nutraceutical for inhibition on postprandial hyperglycemia

In order to facilitate the quality control of Artemisia capillaris, a simple, accurate and reliable HPLC method was developed for the simultaneous determination of the six bioactive compounds: scopolin (1), chlorogenic acid (2), 2,4-dihydroxy-6-methoxyacetophenone 4-glycoside (3), hyperoside (4), isorhamnetin 3-Orobinobioside (5), and scoparone (6), which were selected as the chemical markers of A. capillaris. Separation was achieved on an Agilent Eclipse XDB-C18 column with a gradient solvent system of 0.1% trifluoroacetic acid aqueous-acetonitrile at a flow-rate of 1.0 mL/min and detected at 254 nm. All six calibration curves showed good linearity ($R^2$ > 0.998). A simple reversed phase HPLC method was developed for extracting pharmacologically active compounds scopolin, chlorogenic acid, 2,4-dihydroxy-6-methoxyacetophenone 4-glycoside, hyperoside, isorhamnetin 3-O-robinobioside, and scoparone from A. capillaris using a binary gradient of acetonitrile : 0.1% trifluoroacetic acid with UV detection at 254 nm. The scopolin (1), chlorogenic acid (2), 2,4-dihydroxy-6-methoxyacetophenone 4-glycoside (3), hyperoside (4), isorhamnetin 3-O-robinobioside (5), and scoparone (6) contents of the herb of A. capillaris collected from fifteen district markets in Korea were 0.00~0.90 mg/g, 0.06~7.29 mg/g, 0.06~0.91 mg/g, 0.07~5.05 mg/g, 0.42~13.11 mg/g, and 1.11~29.82 mg/g, respectively. The results demonstrated that this method is simple and reliable for the quality control of A. capillaris.

Randomly Amplified Polymorphic DNA (RAPD) was performed to define the genetic variation and relationships of Artemisia capillaris. Fifteen populations by the distributions and habitat were collected to conduct RAPD analysis. RAPD markers were observed mainly between 300bp and 1600bp. Total 72 scorable markers from 7 primers were applied to generate the genetic matrix, and 69 bands were polymorphic and only 3 bands were monomorphic. The genetic dissimilarity matrix by Nei's genetic distance (1972) and UPGMA phenogram were produced from the data matrix. Populations of Artemisia capillaris were clustered with high genetic affinities and cluster patterns were correlated with distributional patterns. Two big groups were clustered as southern area group and middle area group. The closest OTUs were GW2 and GG1 in middle area group, and GB1 from southern area group was clustered with OTUs in middle area group. RAPD data was useful to define the genetic variations and relationships of A. capillaris.

Artemisia capillaris has been widely used as an alternative therapy for treating obesity and atopic dermatitis. It has been used as a hepatoprotactant. It is also used for ameliorating inflammatory reactions. Although there are several investigations on other Artemisia species, there is no systematic study describing the role of A. capillaris MeOH extract, its solvent soluble fractions, or derived anti-inflammatory principal components in regulating inflammatory conditions. Therefore, the objective of this study was to elucidate anti-inflammatory mechanisms of A. capillaris. Results revealed that MeOH extract of A. capillaris could decrease LPS-stimulated NO secretion. Of tested fractions, $CH_2Cl_2$, EtOAc, and n-BuOH strongly inhibited NO release from RAW264.7 cells. Bioactive mediators derived from $CH_2Cl_2$ and n-BuOH fractions elicited potent anti-inflammatory actions and strikingly abrogated LPS-triggered NO accumulation in RAW264.7 cells. Of particular interest, capillin and isoscopoletin possessed the most potent NO suppressive effects. Western blot analysis validated the molecular mechanism of NO inhibition and showed that capillin and isoscopoletin significantly down-regulated iNOS and COX-2 protein expression. Taken together, our results provide the first evidence that MeOH extract, $CH_2Cl_2$, EtOAc, and n-BuOH fractions from A. capillaris and its derived lead candidates can potently suppress inflammatory responses in macrophages by hampering NO release and down-regulating iNOS and COX-2 signaling.

Objectives : This study was performed to investigate the anti-fibrogenic effect of Artemisiae Capillaris Herba on cultured rat hepatic stellate cells. Materials and Methods : Hepatic stellate cells(HSC-T6) were treated with various concentrations of Artemisiae Capillaris Herba extract for 24 hours. The extraction was done either with distilled water or 50% EtOH. After the treatment, cell viability, proliferation, procollagen levels and the mRNA of the collagen type 1a2 and ASMA were measured by using MTT assay, BrdU assay, RT-PCR, and Procollagen Type I C-peptide EIA Kit. Results : The viability and proliferation of the hepatic stellate cells were decreased as the concentration increased. The mRNA expression decreased consistently with the volume of the secreted procollagen with the extraction made with distilled water, which indicates the herb has inhibitory effect on fibrogenesis of the liver by regulating one of the fibrosis associated genes in transcription. However, it increased in 50% EtOH extraction, which shows that a more stable reaction is expected of the extraction made with distilled water than the extraction made with 50% EtOH. The production of procollagen was decreased by a low-concentration treatment with Artemisiae Capillaris Herba, but increased by a high concentration. It seemed that the cells were responding to Artemisiae Capillaris Herba in low- concentrations, thus producing small amounts of collagen. When the drug was administered at high enough concentration to give direct toxicity to cells, the ability of cells to produce collagen was activated, and the overproduction of collagen was observed as an undesirable results. Conclusion : These results suggest that Artemisiae Capillaris Herba is beneficial in the treatment of cirrhotic patients as well as for the patients with chronic hepatitis when extracted with water in the proper concentrations.
