用HPLC等现代分离技术,从各样少于100g的北极3种石竹科(Caryophyllaceae)植物Stellaria crassipes Hult.、Cerastium arcticum Lange和C.regelii Ostenf.中分得5个新环肽,分别命名为arcticumin A(1)、arcticumin B(2)、arcticumin C(3)、regelin A(4)和crassipin B(5),并通过FAB+-MS和氨基酸组成分析初步鉴定了它们的结构;通过对北极石竹科环肽与青藏高原石竹科环肽的比较,证明了环肽是石竹科的特征成分以及北极地区是石竹科植物分布中心的一个区域.

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.
