  • This study extracted Artemisia capillaris Thunberg with distilled water and ethanol to investigate its antioxidant effect. We then investigated the possibility of producing nanofibers by an electrospinning process by adding the extracts to polyvinyl alcohol (PVA). The electrospinning method used a PVA concentration of 12wt.%, an applied voltage of 10kV, and a tip-to-collector distance of 15cm. Total polyphenol and total flavonoid contents were measured to verify the antioxidant activity of Artemisia capillaris Thunberg extracts (ACEs). The total polyphenol content of the distilled water extract and the ethanol extract were measured as 218.47 and 271.26mg/g, respectively, and the total flavonoid content of the distilled water extract and the ethanol extract were measured as 141.68 and 34.98mg/g, respectively. As the content of the ACEs in the PVA nanofibers increased, the Diameters of the nanofibers and the uniformity of the diameters decreased. The electrospinning process was fabricated in a relatively uniform form without beads, and the diameters of the nanofibers that were produced ranged from 340 to 390nm. The results of FT-IR, XRD and DSC analyses confirmed that the ACEs were well mixed with the PVA molecules and were electrospun.

  • The antimutagenic activity of the extract of Artemisia capillaris THUNB on the mutagenicity induced by benzo(a)pyrene [B(a)P] in the presense of S9 mixture was studied using bacterial mutagenic assay system. Samples harvested in summer and autumn were extracted using ethanol and hot water. Among these extracts the water extract of summer sample had the strongest inhibitory effect against the mutagenenicity of B(a)P, The water extract of Artemisia capillaris THUNB was separated again into ethanol soluble and insoluble parts. The ethanol insoluble part(El) of water extract exhibited higher inhibition effects than the ethanol soluble part against the mutagenic activity of B(a)P. El showed dose-dependent activity on the mutagenicity of B(a)P in SOS Chromotest and Ames test. The 50% inbibition concentraction $(IC_{50}$ of El were $200{\mu}g/assay$ $600{\mu}g/plate$ and $800{\mu}b/plate$ in E. coil PQ37 S. typhimurium TA100 and TA98 respectively. El were showed desmutagenic effect but had no effect on the DNA repair system for B(a)P-induced mutagenesis. HPLC analysis showed that the formation of aflatoxin M1 by cytochrome P-450 1A1 known as playing an impotant role on B(a) P-induced mutagenicity was highly inhibited by El. Therefore we encluded that B(a)P-induced mutagencity can be reduced possible due to the interference of el with cytochrome P-450 1A1-dependent bioactivation.

  • This study was conducted to monitor the quality characteristics of Artemisis capillaris ethanolic extract by response surface methodology. The independent variables were extraction temperature ($X_1$; 60, 70, 80, 90, and $100^{\circ}C$), extraction time ($X_2$; 1, 2, 3, 4, and 5 hr), and ethanol concentration ($X_3$; 0, 20, 40, 60, and 80%). Soluble solid content ($Y_1$), chlorogenic acid content ($Y_2$), and coumaric acid content ($Y_3$), etc. were analyzed as the dependent variables. Estimated optimal conditions for soluble solids were an extraction temperature of $87.65^{\circ}C$, extraction time of 3.19 hr, and ethanol concentration of 42.40%. The optimal extraction conditions for chlorogenic acid were $84.30^{\circ}C$, 3.14 hr, and 47.85%, respectively. Further, those for coumaric acid were $83.45^{\circ}C$, 3.40 hr, and 45.39%, respectively. Extraction conditions for effective components of Artemisis capillaris were superimposed by response surface plots on optimization extraction condition of each dependent variable, including soluble solid, chlorogenic acid, and coumaric acid contents. As a result, superimposed extraction conditions were $80{\sim}90^{\circ}C$, 3~4 hr, and 40~50%, respectively. Under these conditions, soluble solid, chlorogenic acid, and coumaric acid contents were 1.09%, 25.66 mg%, and 20.25 mg%, respectively.

  • 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.

  • Artemisia capillaries is a major important food and medicinal resource in Korea. In order to confirm the biological activities of Artemisia capillaries, we investigated antioxidant and anticancer activities from in vitro assays. The Artemisia capillaries methanol (MeOH) extracts was used for the evaluation of DPPH scavenging, total phenolic content, total flavonoid content, hydroxyl radical (${\bullet}OH$) scavenging, reducing power assay as antioxidant activity, as well as anticancer activities as MTT assay. As a result, the Artemisia capillaries MeOH extracts showed potent antioxidative activity and anticancer activity in vitro. These results suggest that the Artemisia capillaries MeOH extracts have a potential alleviated oxidation process, cell motility activity, and tumorigenesis.

  • In this study, Artemisia capillaries, which has been used as a folk remedy, was investigated for its antimicrobial activity. First, the Aremisia capillaris was extracted with methanol at room temperature, and fractionation of the methanol extracts from Artemisia capillaris was carried out using petroleum ether, chloroform, and ethyl acetate. Second, the antimicrobial activity of the Artemisia capillaris extracts was determined using a paper disc method and minimum inhibitory concentration of ethyl acetate extracts from Artemisia capillaris against food-borne pathogens and food spoilage bacteria was measured. Finally, the growth inhibition curve was determined using ethyl acetate extracts of Artemisia capillaris against Staphylococcus aureus and Salmonella typhimurium. The ethyl acetate extract of Artemisia capillaris showed strong antimicrobial activity against S. typhimurium at a concentration of 1,000 ppm. The 3,000 ppm of ethyl acetate extract from Artemisia capillaris retarded the growth of S. aureus and S. typhimurium for up to 6 hours.
