[Determination of chemical constituents of the essential oil from Cnidium monnieri by GC-MS].
OBJECTIVE
The chemical components of the essential oil from Cnidium monnieri (L.) Cusson were analyzed by GC-MS.


METHODS
The essential oil was extracted from Cnidium monnieri (L.) Cusson by steam distillation, the components analyzed with the different kinds of capillary columns, the optimum separated and analytical conditions were researched, the amount of the components from the essential oil were determinated by normalization method. The separated components were identified by GC-MS.


RESULTS
50 components composed of about 86% of the total essential oil were separated and identified.


CONCLUSIONS
The method is reliable and stable.
