The compositional changes of wormwood (Artemisia princeps var. orientalis) essential oils were studied under 4 different storage conditions i.e., being exposed to air at 20 and $40^{\circ}C$. Sixty-four volatile compounds consisting of 24 terpene hydrocarbons, 18 alcohols, 11 ketones, 6 esters, 1 aldehyde, 2 hydrocarbons, and 2 oxides were identified on the basis of their mass spectra characteristics and retention indices in original wormwood essential oils. Identified compounds constituted 80.53% of the total peak area. Borneol (12.13%) was the most abundant compound, followed by $\alpha$-thujone (8.66%), T-cadinol (6.67%), and 1,8-cineole (6.21%) in original wormwood essential oils. Under the condition of $40^{\circ}C$ of temperature with the cap being opened for 3 min everyday respectively during 6 months of storage, the total amount of functional groups in essential oil determined by peak area percent were decreased by 79.45%, at most. The total level of monoterpene hydrocarbons decreased markedly in the aerobic condition and high temperatures. Whereas the total level of esters increased significantly. Wormwood essential oils were stored in experimental conditions, with the changes in the volatile compounds of essential oils being accelerated by high temperatures and contact with the atmosphere.

The efficiency of three concentrations (0.05, 0.1, and 0.2%) of Ganghwayakssuk (Artemisia princeps Pamp.) extract on the susceptibility of raw chicken nugget batter to lipid oxidation was investigated after 0, 3, 7, and 10 d of refrigerated storage at $4^{\circ}C$. The pH and yellowness values of all treatments were higher than those of the control (p<0.05). Additionally, the lightness and redness values of all treatments were lower than those of the control and as the amount of Ganghwayakssuk ethanolic extracts increased. At the end of the storage period (10 d), the peroxide values (POV), conjugated dienes (CD), and thiobarbituric acid reactive substances (TBARS) values were lower than those of the control. The results show that Ganghwayakssuk prevents lipid oxidation in raw chicken nugget batter.

This research was conducted to investigate the effect of essential oil (EO) from Artemisia Princeps Pampanini on quality of tomato during storage. EO was extracted by steam distillation and diluted by 1 and 2%. Total phenolic contents and antioxidative activities of EO were analyzed. Tomato was packaged corrugated box covered with polypropylene (PP) film containing EO (1 and 2%) and then stored at room temperature for 10 days. During storage, appearance, weight loss rate, soluble solid contents, pH and a (redness) value were measured for tomato. Total phenolic contents of EO increased in a dose-dependence. The DPPH and ABTS radical scavenging activities also showed a concentration-dependent increase. The weight loss rate was lowest using the film packaged in 1% EO. During the storage period, soluble solid contents and pH increased in all treatments. The a value increased regardless of EO concentration in films. Especially, tomato packaged with EO film showed a lower a value than non EO-packaged ones. This result suggests that application of EO to film is effective for tomato quality preservation.

The chromatographic separation of a methanol extract of Artemisia princes led to the isolation of two sesquiterpene lactones, artecanin (1) and canin (2), together with a flavonoid, eupatilin (3). Their structures were determined by 1D, 2D-NMR and MS data analysis. All of the isolates were evaluated for their potential to inhibit the LPS-induced production of nitric oxide in murine macrophage RAW 264.7 cells. Compounds 1 - 3 inhibited nitric oxide production with $IC_{50}$ values of 19.5, 20.4 and 25.1 ${\mu}M$, respectively.

Sajabalssuk (Artemisia princeps PAMPANINI) was extracted with 80% aqueous MeOH, and the concentrated extract was partitioned with EtOAc, n-BuOH and $H_{2}O$, successively. From the EtOAc fraction, two phenylpropanoids were isolated through the repeated silica gel and ODS column chromatographies. From the results of physico-chemical data including NMR, MS and IR, the chemical structures of the phenylpropanoids were determined as eugenol (1) and (-)-sesamin (2). They were the first to be isolated from Sajabalssuk (Artemisia princeps PAMPANINI, Sajabalssuk). Also, eugenol inhibited LDL-oxidation with the inhibitory activity of 87.8 ${\pm}$ 1.0% at a concentration of 40 ${\mu}g/ml$.

Antioxidant and cancer cell growth inhibition activity of hot water extract from five different varieties of Artemisia (A. Argyi H., A. iwayomogi Kitamura, A. Princeps Var Orien talis HARA, A. princeps Pampanini and A. annua L.) in Korea was studied. We determined the phenol and flavonoid contents and examined antioxidant assay, such as DPPH, NO radical scavenging, activity ferric-reducing antioxidant power (FRAP), and bleaching inhibition activity in the ${\beta}$-carotene linolic acid system. Also, we performed HeLa and MCF-7 cancer cell growth inhibition assay of Artemisia extracts. Total phenol and flavonoid contents were the highest in A. iwayomogi Kitamura followed by A. Argyi H. DPPH radical scavenging activity was the highest in A. Argyi H. at 50 ${\mu}g/ml$ concentration, NO radical scavenging activity was more than 50% in A. Princeps Var Orien talis HARA, A. princeps Pampanini, and A. annua L. at 200 ${\mu}g/ml$ concentration. FRAP was higher in A. Argyi H. and A. iwayomogi Kitamura. Antioxidant activity in the ${\beta}$-carotene linolinolic system was also higher in A. Argyi H. and A. iwayomogi Kitamura by 60.50% and 56.90% at 100 ${\mu}g/ml$ concentration, respectively. In cancer cell growth inhibition activities at 400 ${\mu}g/ml$ concentration, A. iwayomogi Kitamura showed greater than 80% on HeLa cell. A. princeps Pampanini and A. Argyi H. extract had growth inhibition activities greater than 80% on MCF cell. The results of this study suggest that the antioxidant and anticancer activities in various Artemisia are a promising source of functional food ingredients.

Physical, chemical and biological properties of soils and cadmium(Cd) content of Artemisia princeps var. orientalis collected from 10 metalliferous mines were analysed. Cd contents of unplanted soils and rhizosphere soils were not significantly different(p < 0.05), and mean values were 5.92 and 5.91 mg/kg, respectively. In addition, Cd content of rhizosphere soils were correlated with Cd content of Artemisia princeps (p < 0.05, ${R^2}_{shoot}$ = 0.3120, ${R^2}_{root}$ = 0.4177). Minimum data set(MDS) of soil quality parameters for statistical assessment of Cd uptake was established by principal component analysis, and it was identified as organic matter(OM), dehydrogenase activity(DHA), pH, exchangeable Mg. According to multiple regression analysis using the MDS, coefficients of determination ($R^2$) for Cd uptake of shoot and root of Artemisia princeps were found to be 0.3418 and 0.5121, respectively. This suggests that statistical soil quality assessment using the MDS seems a useful tool to interpret heavy metal uptake of plant.

Antioxidant properties of Artemisia princeps Pamp were determined using in vitro assay systems against 1,1-diphenyl-picrylhydrazyl (DPPH) radical, superoxide ($O_2{^-}$), hydrogen peroxide ($H_2O_2$), hydroxyl radical ($HO{\cdot}$) and nitric oxide (NO) radical, as well as rat liver microsomal lipid peroxidation. Among the five solvent fractions, ethyl acetate fractions showed the highest total polyphenol and flavonoid contents at $311.35{\mu}g/mg\;and\;92.73{\mu}g/mg$, respectively. Ethyl acetate fractions, except for $H_2O_2$ scavenging activity, also showed the highest scavenging activity; the 50% inhibitory concentration ($IC_{50},\;{\mu}g/mg$) values for DPPH, superoxide, $HO{\cdot}$ and NO radical scavenging were 52.71, 26.47, 58.92 and 65.94, respectively. Additionally, the highest inhibition of rat liver microsomal lipid peroxidation was observed by ethyl a cetate fraction.

Recently, management and restoration efforts using the plants promote the disturbed habitats such as a set-asides or field boundaries. But, side effects are coming out because of using the exotic plants in restoration process. This study was conducted to select the native plant species used for restoration through the vegetation survey and plant community analysis at small stream-side in rural villages. We surveyed at two small stream-sides in open field and high land area in 2005 as a case study. Total 126 species was found at small stream side in open field area. As the result of important value' calculation, Persicaria thunbergii 23.0%, Humulus japonicus 18.6%, Phragmites communis 4.4%, Bromus japonicus 4.2%, and Rosa multiflora 3.4% were in the order of important value. Total 92 species were found at small stream side in high land area. As the result of important value' calculation, Dactylis glomerata 16.1%, Artemisia princeps var. orientalis 11.0%, Persicaria thunbergii 10.9%, Humulus japonicus 9.3%, Phragmites japonica 5.2% and Phragmites communis 3.5% were in the order of important value. We selected some plant species to use in restoration after due consideration of problems of exotic plant and high coverage and density species, and ecological process; Persicaria thunberii, Phragmites communis, Bromus japonicus, Rosa multiflora, Equisetum arvense, Digtaria sanguinalis, Impatiens textori, and Artemisia princeps var. orientalis in open field stream-side, and Artemisia princeps var. orientalis, Persicaria thunbergii, Phragmites japonica, Phragmites communis, Artemisia selengensis, Panicum bisulcatum, Rorippa indica, and Equisetum arvense at hghland stream-side. We will verify the selected native plants and plan the utilization of the native plants in restoration at stream-side in rural village.
