  • The antioxidant activity of Artemisia montana was determined by measuring the radical scavenging effect on 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical and inhibitory activity against free radical generation of hepatocytes ($AC_2$F). The methanol extract of A. montana showed strong radical scavenging activity at a concentration of $10.1{\mu}g/m{\ell}$, and thus fractionated by solvent extraction. Esculetin and luteolin 7-O-rutinoside (scolymoside) were isolated as the active principles from the EtOAc and interphase fractions, respectively. The antioxidant activity of these compounds were comparable to that of L-ascorbic acid.

  • Mugwort (Artemisia montana), which is a perennial plant mainly distributed throughout Northeast Asian regions, has been used as a preferred source of various foods and traditional medicines in Korea. In particular, as essential oils extracted from mugwort were reported to be biologically active, its steam distillate has been widely used to treat various conditions, such as itching, hemorrhoids, and gynecological inflammation. Therefore, efforts have been devoted to develop effective methods for the collection of bioactive essential oils from mugwort. In this study, five mugwort extracts were obtained using different extraction conditions, namely, 6 % ethanol at room temperature and at 80 ℃, pure ethanol, n-hexane, and an adsorbent resin. To evaluate the five extracts of mugwort, area-under-the-curve values (AUCs), chemical profiles, and major bioactive essential oil contents were investigated using gas chromatography-mass spectrometry (GC-MS). An overall assessment of the volatile components, including essential oils, in the five extracts was conducted using AUCs, and the individual essential oil in each extract was identified. Furthermore, the four major essential oils (1,8-cineole, camphor, borneol, and α-terpineol), which are known to possess anti-microbial and anti-inflammatory activities, were quantified using authentic chemical standards. Based on the evaluation results, pure ethanol was the best extractant out of the five used in this study. This study provides evaluation results for the five different mugwort extracts and would be helpful for developing extraction methods to efficiently collect the bioactive oil components for medical purposes using chemical profiles of the extracts.

  • This study was conducted to evaluate the shoot height at which the yield and nutritive value of wormwood (Artemisia montana) is optimized in order to provide information on its potential to support animal production (Experiment 1). A second objective was to determine how the essential oil (EO) concentration in wormwood hay and silage differ (Experiment 2). In Experiment 1, Artemisia montana was harvested at five different shoot heights (20, 40, 60, 80 and 100 cm) from triplicate $1.8{\times}1.8m$ plots. Dry matter (DM) yield was measured at each harvest date and the harvested wormwood was botanically separated into leaf, stalk and whole plant fractions and analyzed for chemical composition and in vitro dry matter digestibility (DMD). Values for total digestible nutrients (TDN), digestible energy (DE) and metabolizable energy (ME) were subsequently calculated using prediction equations. Dry matter yields of stalk and whole plant increased linearly (p<0.001) and leaf yield increased quadratically (p<0.01) with shoot height, whereas the leaf/stalk ratio decreased linearly (p<0.001). As shoot height increased, there was a linear increase (p<0.001) in leaf DM, ether extract (EE) and neutral detergent fiber (NDF) contents and a quadratic increase (p<0.05) in leaf acid detergent fiber (ADF) and nitrogen free extract (NFE) contents, and stalk and whole plant DM (p<0.001), organic matter (OM, p<0.01 and p<0.05), NDF (p<0.001 and 0.05) and NFE (p<0.05) contents. However, there were decreases in leaf crude protein content (CP, quadratic, p<0.001) and stalk and whole plant EE content (linear, p<0.001), CP (quadratic, p<0.05) and ash (quadratic, p<0.05) contents. Digestibility of DM and TDN, and DE and ME value in leaves were not affected by increasing shoot height, but these measures linearly decreased (p<0.001) in stalk and whole plant. In Experiment 2, the hay had higher DM and CP concentrations, but lower EE concentration than the silage. Essential oil (EO) content in wormwood silage (0.49 g/100 g DM) was higher (p<0.05) than that in wormwood hay (0.32 g/100 g DM). Wormwood hay contained 25 essentail oils (EO) including camphor (10.4 g/100 g), 1-borneol (11.6 g/100 g) and caryophyllene oxide (27.7 g/100 g), and wormwood silage had 26 EO constituents including 3-cyclohexen-1-ol (8.1 g/100 g), trans-caryophyllene (8.6 g/100 g) and ${\gamma}$-selinene (16.8 g/100 g). It is concluded that the most ideal shoot height for harvesting wormwood is 60 cm based on the optimization of DM yield and nutritive value. Wormwood silage had a greater quantity and array of EO than wormwood hay.

  • To investigate the plants invasion process and dominant species in large-scale cutting slopes, slopes elapsed one year to thirteen years after construction had been selected in five counties. The obtained results are summarized as follows : The species of high appearance frequency were Alnus firma, Arundinella hirta, Miscanthus sinensi var. purpurascens, Erigeron cancdensis, Artemisia princeps var. orientalis, Oenothera odorata, Lactuca raddeana, Lactrca indica var. laciniata, Lespedeza bicolor, Youngia sonchifolia, Populus albaglandulosa, and so on. The biological type of identified vascular plants was $Ch-D_1-R_{5-e}$. In time, plant coverage was increased gradually and average of plant coverage was 1.17% in slopes which elapsed one year, 42.44% after six years, 56.67% after eight years, and 69.17% after ten years. The dominant species in the surveyed slopes were covered with Alnus firma, Artemisia princeps var. orientalis, Erigeron cancdensis, Miscanthus sinensi var. purpurascens, Arundinella hirta, Lactuca raddeana, Oenothera odorata, Boehmeria spicata, Kummerowia striata and Artemisia montana of the 59 species. The conditions of location in large-scale cutting slopes are hard to fix and germinate of seeds, and extend plant roots in the slope soil. Hence, the highly appearance species and dominance species of the area will make plant coverage quick and slope stable.

  • This study was carried out to investigate the effect of replacing dried mugwort (Artemisia montana Pampan) in concentrate a time of preparation pellet. The treatments, arranged in a 4${\times}$4 Latin square design, were four additional levels of mugwort at 0, 3, 5 and 10% in concentrate. Four crossbred (CorriedalexPolwarth, t) sheep with a mean body weight of 41.3 kg were used to evaluate nutrients digestibility, palatability, fermentation characteristics and microbial protein synthesis in the rumen. The digestibility of crude protein was improved (p < 0.05) to 6.1 % - 8.6 % in sheep fed 3, 5 and 10% mugwort pellet treatments compared with that of control. That of crude fat and NDF was improved (p < 0.05) to 5.8 % - 7.3 % in sheep fed 3 % compared to other treatments. The ruminal pH was significantly (p < 0.05) decreased in sheep fed 3 % mugwort pellet compared to other treatments when observed at 0.5 hour after feeding. The ammonia nitrogen concentrations were the highest in sheep fed all treatments at 1 hour after feeding. The ruminal concentrations of acetic acid and propionic acids were an improvement (p < 0.05) at the 3% and 5% treatments. Retained nitrogen of 3, 5 and 10% treatment with the value of 2.24 - 2.82 g was higher (p < 0.05) than that of the control with 0.78 g and microbial protein production of 10% treatment was higher (p < 0.05) than that of control. This study suggested that the replacing with 3% dry mugwort (Artemisia montana Pampan) in concentrate a time of preparation pellet will improve nutrient digestibility, palatability, ruminal fermentation characteristics and feed value.

  • The purpose of this study was to examine the ecological characteristics of herbaceous communities by systematic and scientific analysis of their structure and diversity in the Midongsan Arboretum and to offer raw data for a long-tenn monitoring study. The importance value and diversity index of species appearing in twenty plots from July to September, 2004 were analyzed and a management plan for these communities is presented. Vascular plants were represented by 60 taxa of 23 families, 51 genera, 50 species and 10 varieties. Based on the results of importance value analysis, the most dominant species was Artemisia princeps var. orientalis, followed by Setaria viridis and Erigeron canadensis. The diversity index analysis showed that plot no. 5 had the highest H' and H'_{max}$(2.0135 and 2.6391). It's species composition was comparatively more diverse and it's structure more stable than other plots. Artemisia montana and Dactylis glomerata showed the highest correlation between species. Because herbaceous communities are important biological habitats and provide important function in environmental conservation, it is important to properly preserve these communities. At the same time, in order to preserve genetic resources and improve spatial function, it may be necessary to consider removing herbaceous communities in certain areas. In the future, the relations between physicochemical soil properties and herbaceous communities should be examined and community movement should be studied.
