regelii originated in Arctic Region have been studied by GC/MS. Total fifty-three chemical constituents were identified by analysis of these data. It has been further proved that Stellaria and Cerastium are two genera with close relationship.

• 通过gc MS方法对采自北极的Stellariacrassipes,Cerastiumarcticum和Cerastiumregelii3种石竹科植物挥发油成分进行了研究 ,共得到 54种化学成分 ,对这些挥发油成分的进一步分析 ,证明了Stellaria和Cerastium具有较近的亲缘关系。
