Vascular plant diversity of Gwangdeoksan Mountain (Cheonan-Asan, Korea): insights into ecological and conservation importance

Abstract

Gwangdeoksan Mountain (699.3 m) is the highest border mountain between the two cities of Chungcheongnamdo Province, Cheonan and Asan, Korea. In this study, we investigated the flora of Gwangdeoksan Mt. from April of 2015 to October of 2017. Through 20 independent field investigations, we identified and tallied a total of 428 species, 9 subspecies, 30 varieties, and a forma in 287 genera and 97 families. Of a total of 468 taxa, 128 taxa in 112 genera and 58 families were found to be Korean endemic species (7 taxa), floristic regional indicator species (45 taxa), rare or endangered species (3 taxa), species subject to the approval of outbound transfer (73 taxa), and alien or ecosystem disturbing species (32 taxa). The flora of Gwangdeoksan Mt. can be divided into four distinct floristic subregions, with higher diversity in the north-facing subregion. The complex flora of Gwangdeoksan Mt., emerging at the edge of two floristic regions of the Korean peninsula, may represent a significant conservation priority and a topic for future ecological and geographical studies.

Anti-adipogenic activity of Smilax sieboldii extracts in 3T3-L1 adipocytes

“…최근에는 천연물을 이용하여 지방생성 조절을 기반으로 하는 항비만 활성 평가에 관한 연구가 주목 받고 있으며, 이 중 청 가시덩굴(Smilax sieboldii)은 국내 산지 숲속에서 자라는 덩굴 성 식물로 청미래덩굴과(Smilacaceae) 청미래덩굴속(Smilax)에 속하는 산림자원이다 [9]. 청미래덩굴은 잎이 두껍고 윤기가 나 며 열매가 붉지만, 청가시덩굴은 잎이 보다 얇고 열매는 검은 빛을 띄는 특징이 있다.…”
