  • Inhibitory effects of 200 medicinal plants on elastase activity were screened. Among the 200 plants, six plant extracts exhibited more than 65% of inhibition on elastase activity by their total methanol extracts at 1, 000$\mu\textrm{g}$/$m\ell$ as a final concentration. For six active plants including Areca catechu, Cinnamonum cassia, Myristica frograns, Curcumma longa, Alponia katsumadai, and Dryopteris crassirrhizoma, the inhibitory effects of their comsituents were examined on the activity of human leukocyte elastase, hyaluronidase and lipid peroxidation. In lipid peroxidation assay using TBA method, three of the 6 plants including Curcumma longa, Areca Catechu and Alponia katsumadai exhibited more than 70% of inhibition at the concentration of 1, 000$\mu\textrm{g}$/$m\ell$, but only one plant, Areca Ctechu showed high inhibitory effect on hyaluronidase activity. The results suggest that medicinal plants showing several biological activities may be potent inhibitors of anti-aging process on skin and that might be useful for application in cosmetics.

  • Although Myanmar is a biodiversity hotspot, little is known about its flora, particularly lycophytes and ferns, due to a lack of intensive inventories. In 2017, work on a total of 299 species of lycophytes and ferns found throughout the country, including 84 species from Natma Taung National Park in the Chin State, was published. However, a comparison of the flora of Myanmar with those of adjacent countries suggests that many more species are likely also to be distributed in this country. In the present study, two field surveys conducted in Natma Taung National Park during 2015 to make a checklist of lycophytes and ferns resulted in the discovery of three fern species not previously recorded in the flora of Myanmar. All occur in other countries in Southeast Asia as well as in other tropical areas. These species are Pteris bella (Pteridaceae), Dryopteris lepidopoda (Dryopteridaceae), and Loxogramme duclouxii (Polypodiaceae). The results will provide valuable information for the Myanmar fern checklist that is currently being prepared.

  • 백두대간 마루금일대 침엽수 자연림의 식생형이 Braun-Blanquet방법과 TWINSPAN을 병용하여 분류되고 그 생태적 특성이 분석되었다. 식생형은 소나무-가는잎그늘사초형과 잣나무-관중형 등 2개의 상위단위와 7개의 하위단위로 유형화되었다. 단위면적당($/100m^2$) 평균종풍부도와 총피도율은 각각 $21.9{\pm}8.9$종류, $146.9{\pm}32.3$%이었다. 식물상 특성은 82과 217속 387종류이었으며, 국화과, 백합과, 장미과 등이 전체 구성종의 약 25.6%를 차지하고 있었으며 단 1종만 출현하는 과도 7.8%에 달하였다. 총피도율에 의한 상대적 중요치는 소나무과가 19.2로 가장 높았으며 과별 종풍부도 경향과 다소 반대로 나타났다.

  • This study was conducted to investigate the environmental characteristics of natural habitats, and the genetic variations in samples from 19 different quadrates of Asplenium scolopendrium 10 habitats. The natural habitats of A. scolopendrium were located at an altitudes 110-973 m with inclinations of $7-30^{\circ}$. All the quadrates were located on north facing slopes. The average field capacity of the soil is 31.4%, with organic matter at 16.7%, and the pH is 5.84. The soil texture was confirmed as sandy loam in 8 habitats and silt loam in 2 habitats. A total of 214 vascular plants were identified from 10 habitats. The importance value of the herbaceous layer (H) was the highest in A. scolopendrium, at 10.4%, followed by Arachniodes standishii (7.3%), Dryopteris crassirhizoma (6.5%), and Polystichum tripteron (5.3%), which implies that the natural habitats of A. scolopendrium are affinity with ferns. The species diversity of A. scolopendrium was estimated as on average 1.09, while the dominance and evenness were 0.12 and 0.87, respectively. The result of the RAPD analysis, among 59 bands amplified with a primer, 25 (42.4%) showed polymorphism. Twenty-one individuals of 10 habitats could be classified into four groups with similarity coefficient values ranging from 0.74 to 1.0. Mt. Mullae and Geumdaebong populations shows basal branching within the 21 individuals. Ulleung-do island and Jeju-do island population forms an independent clade, respectively. Mt. Moak and Byeonsan-bando clade formed a sister to the Ulleung-do island and Jeju-do island clade.

  • 제주도에 자생하는 양치식물 25종을 대상으로 항산화활성, ACE 저해활성, APN 저해활성 및 $\alpha$-amylase 저해활성을 검색하였다. 항산화활성은 쇠고비와 일색고사리에서 비교적 높아서 항산화 음료로 애용되고 있는 차나무 잎보다도 더 높았다. ACE 저해활성과 APN 저해활성은 전체적으로 낮았으나, 쇠고비에서 각각 26.7%와 28.2%으로 비교적 높은 저해활성을 나타내었다. $\alpha$-Amylase 저해활성은 10종이 50% 이상의 높은 활성으로 보였으며, 그 중에서 쇠고비와 홍지네고사리의 저해활성이 특히 높았다. 이상의 결과로부터 쇠고비는 항산화활성뿐만 아니라 ACE 저해활성, APN 저해활성과 $\alpha$-amylase 저해활성 모두 다른 식물에 비해 높아 생리활성 물질의 분리 및 동정 등 식품소재 및 식물생약으로 이용하기 위한 후속 연구가 기대된다.

  • This study was conducted to analysis the ecological characteristics of "Wando HolIy"$(llex{\times}wandoensis)$ which is expecting as a possible ornamental tree with its beautiful leaves, flowers and fruits, and to find special breeding material which have particular characteristics and also provide correct environmental information which are required for commercial cultivation. The hill of Galmoon-Ri, Gunoei-Myon, Jeonnam Province, Korea, were reported as a original habitat of native $llex{\times}wandoensis$. The investigation shows that soil pH of native habitat was 6.18, hardness was 2.39, humidity was 38.6%, direction of slope is SSW, and average inclination was $15^{\circ}. The vegetation around $I.{\times}wandoensis$ is occupied by trees like an Quercus variabilis, Q. serrata, Q. acuta and so on. These are mixed forest of deciduous trees. Tree height reached up to about 12m and its coverage is about 30%. Q. salicina, Camellia japonica, I. integra, Cryptomeria japonica account for sub-tree layer. Tree height is around 8m and coverage is about 20%. Shrub layer was taken by Viburnum furcatum, Callicarpa japonica, Styrax japonica, Eurya japonica, Lindera obtusiloba, Ligustrum japonicum, Smilax china, Cornus walteri etc. Tree height reaches around l.2m and coverage is around 20%. Herb layer includes Trachelospermum asiaticum var. intermedium, Cymbidium goeringii, Dryopteris bissetiana, Disporum viridescens, Disporum smilacinum, Sasa borealis var. gracilis etc. Trachelospermum asiaticum var. intermedium, which are observed in southern evergreen zone, are dominant and its coverage is around 20%. The native habitat was in spoiled condition because of artificial thin out.

  • In recent years, the view centered conservation for eco-system is getting important rather than development from human oriented perspective. As a result, the concept "Sustainable development", that is seeking harmony between conservation and development, appeared so that we researched distribution and status of vascular plants a site of project in the Bukkyungnam substation. The main findings from the study is as follows. The vascular plants a site of project in the Bukkyungnam substation area was listed 435 taxa; 93 families, 269 genera, 377 species, 1 subspecies, 51 varieties and 6 forms. Specific plant species by floral region were total 25 taxa; Acer palmatum (Planted species), Asperula lasiantha in Class III, Caryopteris incana, Cirsium schantarense in Class II, 21 taxa (Dryopteris erythrosora, Chloranthus japonicus, Salix glandulosa, Alnus hirsuta, Quercus variabilis, Ulmus parvifolia, Clematis patens, Rubus hirsutus, Euphorbia pekinensis, Cayratia japonica, Grewia biloba var. parviflora, Vaccinium oldhami, Microstegium japonicum, Hosta capitata, Polygonatum falcatum, etc.) in Class I. Based on the list of Korean endemic plants, 10 taxa were recorded; Cephalotaxus koreana, Populus tomentiglandulosa (Planted species), Indigofera koreana, Forsythia koreana (Planted species), Paulownia coreana (Planted species), Asperula lasiantha, Weigela subsessilis, Adenophora triphylla var. hirsuta, Carex okamotoi, Lilium amabile and based on the list of the rare plants by the Forest ResearchInstitute, 2 taxa were recorded in the studied areas; Lilium callosum (Preservation priority order; No. 191), Aristolochia contorta (No. 151). The naturalized plants in this site were 13 families, 22 genera, 28 taxa and naturalization rate was 6.4% of all 435 taxa vascular plants.
