[Objective] To determine chemical composition of volatile oils from Cnidium monnieri(L.) Cuss. in Hebei Province by GC-MS.[Methods]Volatile oils were extracted from Cnidium monnieri(L.) Cuss. by steam distillation method; chemical composition of volatile oils from Cnidium monnieri(L.) Cuss. was determined by GC-MS; relative percentage content of chemical composition was determined by normalization method. [Results]42 major components were identified,including alpha-pinene(18. 19%),limonene(17. 88%),borneyl acetate(11.05%),and camphene(7.81%),etc. [Conclusion]This method is simple and fast and highly efficient. This study can be applied for determining chemical composition of volatile oils of traditional Chinese medicines,and is expected to provide basis for scientific quality control of Cnidium monnieri(L.) Cuss.
