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
