  • Aster glehni was extracted by microwave-assisted extraction(MAE) and reflux extraction(RE) methods and their extraction efficiencies were compared. A considerable reduction in extraction time was achieved by MAE. When 70% methanol, 50% methanol, 70% ethanol, or 50% ethanol was used, MAE extract contained nearly same amounts of soluble solid and total polyphenol contents as obtained by RE. The optimum MAE conditions for the extraction of Aster glehni were $120{\sim}150$ watts of microwave energy and $4{\sim}8$ minutes of extraction time. No significant changes were found in electron donating ability(EDA) over the variation of microwave energy or extraction time. The use of diluted methanol or ethanol resulted in improving extraction yield(24%), total polyphenol content(2.6%) and EDA(60%).

  • In an attempt to find the activity of Aster glehni (Compositae) leaves on the obesity in vivo, 30% ethanolic extract rich in caffeoylquinic acids was orally treated with 100 and 200 mg/kg for consecutive four weeks during feeding high-fat diet in rats for 6 weeks. This extract prevented the increase of atherogenic index and body weight and oxidative stress from dietinduced obese rats probably due to the pharmacological mechanism of the CQ complex.

  • 산채는 사람에 의하여 개량 육성되어 논밭에서 재배하고 있는 농작물과 달리 자연 그대로 산야에서 자생하는 식물 중 식용으로 가능한 것을 말한다. 우리나라 산야에는 480종의 식물이 식용으로 이용될 수 있다고 하나 현재 전국에서 재배하고 있는 작목은 36종으로 추정되며, 앞으로도 80여 종이 개배 가능한 작물로 추정된다. 산채류의 이용형태별 생산가능시기는 3~5월의 생채 생산과 6~7월의 건채 생산으로 소비자의 기호에 부합하는 신선 생채의 소비한계는 제한되어 있기 때문에 재배유형별 생채 수량검정을 통해 수확시기 연장 및 재배품목을 다양화 시킬 필요 있다. 이에 본 시험은 산채류 재배유형별 수확기간을 구명하고자 표고 500 m의 전북 남원시 허브산채시험장에서 2018년 5월 말 갯기름나물 등 15 종을 노지와 하우스에 정식하여 각 작물의 생육특성, 수확한계기 등을 조사하였다. 1년차 지상부 생육특성을 조사한 결과 참취, 개미취, 섬쑥부쟁이, 질경이, 갯기름나물, 두메부추, 돌단풍, 참당귀의 경우 초장, 엽장 등은 노지보다 하우스에서 높은 편이었고 생존율은 비슷하거나 하우스에서 더 높은 경향을 보였다. 우산나물, 단풍취의 생존율은 하우스에서 더 높았으나 생육 초기 엽소현상으로 인해 1년차 생육은 노지, 하우스에서 둘 다 저조하였고 곤달비, 어수리, 곰취, 눈개승마의 경우 노지에서는 7월 중순이후 지상부가 전부 고사하였으나 하우스에서는 생존율이 상대적으로 양호하여 11월 상순까지 후기 생육을 하였다. 2년차 산채류 출현기 조사한 결과 하우스 재배에서 산마늘이 2월 중순으로 가장 빨랐고 갯기름나물, 곤달비 등 10종이 2월 하순에 출현하였으며 참당귀 3월 상순, 단풍취 및 우산나물 3월 중순, 돌단풍이 가장 늦은 3월 하순에 출연하였다. 생체수확 시기는 갯기름나물, 눈개승마, 산마늘, 두메부추, 섬쑥부쟁이는 3월 중순부터 가능했고 곤달비 등 12개종은 3월 하순, 우산나물은 4월 상순, 돌단풍은 4월 중순으로 가장 늦게 생체수확이 가능했다. 노지 재배의 경우 산마늘과 눈개승마가 3월 중순으로 가장 빨랐고 갯기름나물 등 10종이 3월 하순에 출현하였으며 돌단풍, 참당귀, 단풍취가 4월 상순으로 가장 늦은 출연을 보였다. 생체수확 시기는 눈개승마와 산마늘이 4월 상순으로 가장 빨랐으며 갯기름나물 등 10종이 4월 중순부터 가능했고 돌단풍, 참당귀, 단풍취가 4월 하순으로 가장 늦었다. 수확한계기 조사 결과 눈개승마, 산마늘, 우산나물은 하우스 및 노지재배에서 20일정도로 가장 짧았으며 그 외 작물들은 계속적으로 수확이 가능하였으나 6월 상순 이후에는 품질이 나빠져 생체상품으로서 가치가 없었다.

  • 14 kinds of perennial flower sods, including 10 Korean native wild perennial flowers such as Lychnis cognata, Achillea sibirica, Sedum spectabile, Sedum takesimense etc. were made with basal sheets of nonwoven fabric or jute fabric. Growth of plants planted on bark was better than that of planted on soil of open area. The plants planted on bark also showed difference in growth rate by the kinds of used basal sheets. In general, the growth of plants was good when nonwoven fabric was used as basal sheet instead of jute fabric. When jute fabric was used as basal sheet, It was severely decayed during growth period resulting in great decreasing of root sticking capacity to basal sheet. It was shown that the procumbent plants such as Tymus quinquecostatus, Ixeris stolonifera, Sedum oryzifolium, Sedum polystichoides having lower plant height and better ground coverage ability compared with upright plants such as Sedum spectabile and Aster glehni were more suitable for floral sod production.

  • This study was conducted to provide ecological basic data that use to establish environmental conditions for cultivation of wild vegetables in 2016-2018. Therefore, we investigated the vegetation structure and the correlation between the community structure and the environmental factors for natural habitats of wild vegetables(Aster glehni, Allium ochotense, and Aruncus sylvester) distributed in Ulleungdo. As a result of population and gradient analysis, the vegetation was classified into Aster glehni community, Allium ochotense community, and Aruncus sylvester community. We confirmed that the classification by population analysis was consistent with that by TWINSPAN method, suggesting that they were complemented each other. The importance value of Aster glehni was the highest in all communities, followed by Aruncus sylvester, Allium ochotense, Hydrangea petiolaris, Dryopteris crassirhizoma, Asperula ldorata, Phryma leptostachya var. asiatica, Disporum viridrescens, Hedera rhombea, Anthriscus sylvestris, and Hepatica maxima. According to the results of DCCA ordination analysis, among those communities, the Aster glehni community was distributed in soil where the nutrition including T-N and O.M. were intermediate. The Allium ochotense community was distributed on the a little high northern slope at the highest altitude where the CEC and O.M. were the highest, and other nutrition and pH were low. The Aruncus sylvester was distributed on high slope and altitude on which the amount of exchangeable cation such as $Ca^{{+}{+}}$, $Mg^{{+}{+}}$ and pH were high, and the CEC, $P_2O_5$, and O.M. were the lowest.

  • Spray drying was used a means for microencapsulation of Aster scaber and Aster glehni. The optimum conditions of spray drying were found to be 210$^{\circ}C$ for the inlet temperature and 5 $m\ell$/min for the feeding rate. The color difference decreased by 12∼25 % far the herb extracts depending on storage temperatures. With an increase in storage temperature, color of the control changed considerably compared to microencapsulated powders. This is due to the fact that wall materials minimized effect of oxygen on the herb extracts. Microencapsulated powders in the amounts of 50 ppm and 250 ppm added to hydrogenated soybean oils led to lower acid values and conjugated diene values during 6 day storage. Compared to the control, the herb extracts displayed 16∼48% increase in antioxidation effect, while the microencapsulated powders exhibited 46∼88% increase. Extracts also showed lower conjugated dienoic acid contents than those of the control. Although antioxidation effect of the microencapsulated powders did not prevail on the significant level in the early stage of storage of oils tested, it became predominant after one week of storage as wall materials were gradually degraded under the high temperature thereby releasing core material from the microcapsule.

  • Ulleungdo, a volcanic island, has different climate, soil, and topography characteristics from inland of the Korean Peninsula. Its agriculture also exhibits distinctive features. This study focused on floristic compositions and characteristics of crop lands in Ulleungdo. Flora surveys were conducted for 37 areas three times, one in May of 2016, one in July of 2020, and one in August of 2020. Results showed that vascular plants of crop lands in Ulleungdo included 186 taxa of 53 families, 132 genera, 160 species, 14 varieties, five subspecies, and five hybrids. Asteraceae had the most diverse species (33 taxa), followed by Poaceae (25 taxa), Fabaceae (12 taxa), Polygonaceae (11 taxa), and Liliaceae (nine taxa). The biological type of crop lands in Ulleungdo island was determined to be Th-R5-D4-e type. Rare plants were found for nine taxa: Athyrium acutipinnulum Kodama ex Nakai, Sedum takasimense Nakai, Rubus takesimensis Nakai, Dystaenia takesimana (Nakai) Kitag., Ligustrum foliosum Nakai, Aster pseudoglehni Y.Lim, Cirsium nipponicum (Maxim.) Makino, Lilium hansonii Leichtlin ex D.D.T.Moore, and Polygonatum robustum (Korsh.) Nakai. In addition, 45 taxa contained naturalized plants of 13 families, 33 genera, 44 species, and one variety. Urbanization and naturalization indices were 13.9%, and 24.2%, respectively.

  • This study was carried out to decide ITS (internal transcribed spacer) sequence of some Korean native $Aster$ species and to resolve their relationship among Korean native $Aster$, including $Kalimeris$, $Gymnaster$, $Heteropappus$ genus separated from $Aster$ in a previously study based on the pappus length. We registered 11 ITS sequences of $Aster$ species including $A.$ $glehni$ to GenBank and those sequences were used for the cluster analysis with $Kalimeris$ species. The size of ITS1 was varied from 248 to 256 bp, while ITS2 was varied from 220 to 222 bp. The G + C content of the ITS region ranged from 49.4 to 53.5%. Pairwise comparison results showed that the substitution rate of ITS1 and ITS2 region was 9% and 10%, respectively. $Kalimeris$ sensu strict substitution rate was lower than that of $Aster$ sensu strict species. The strict consensus parsimonious cluster analysis showed $A.$ $tripolium$ is the first branching from the clade and the next is $A.$ $scaber$. The $Kalimeris$ species except for the $A.$ $hispidus$ were grouped into the same clade with high bootstrap value (91%) within $Aster$. $Gymnaster$ and $Heteropappus$ that has been classified by morphological characters were also grouped into broad sense $Aster$ clade. These results implied these three genera could be merged together into $Aster$ based on the ITS sequences.
