Cyclopeptides from Three Arctic Caryophyllaceae Plants, Chemotaxonomy and Distribution Significance of Caryophyllaceae Cyclopeptides
Abstract: Five new cyclopeptides named arcticumin A (1), arcticumin B (2), arcticumin C (3), regelin A (4) and crassipin B (5) were isolated from three arctic Caryophyllaceae species (＜100 g), Cerastium arcticum Lange, C. regelii Ostenf. and Stellaria crassipes Hult., with structures elucidated prim...

| Summary: | Abstract: Five new cyclopeptides named arcticumin A (1), arcticumin B (2), arcticumin C (3), regelin A (4) and crassipin B (5) were isolated from three arctic Caryophyllaceae species (＜100 g), Cerastium arcticum Lange, C. regelii Ostenf. and Stellaria crassipes Hult., with structures elucidated primarily by FAB+-MS and amino acids analysis. Based on the comparison of Caryophyllaceae cyclopeptides from both the Qinghai-Xizang (Tibet) Plateau and Arctic region, it is proposed that cyclopeptides are characteristic components of Caryophyllaceae and Arctic region is one part of the distribution center of Caryophyllaceae. Key words: Stellaria crassipes; Cerastium arcticum; Cerastium regelii; Caryophyllaceae; cyclopeptides; Arctic region; chemotaxonomy; distribution The Caryophyllaceae is an important plant family, con-taining 60 genera and over 2 000 species in the world. In most taxonomic literatures, Caryophyllaceae is usually di-vided into three subfamilies, namely Paronychoideae, Alsinoideae, and Caryophylloideae (Lu et a l., 2003). Biogeographically, Caryophyllaceae is almost d istributed all over the world, some species of which are found in Arc- |
