Steam distillation was used to extract volatile oils from generations of flowers. Different types of capillary columns were used for analysis to find out the best conditions for analysis. The percentages were determined by normalization and the volatile oils of generations were analyzed by gas chromatography-mass spectrometry. The analysis of chemical composition was carried out. A total of 39 components were identified, accounting for more than 86% of the total volatile oil components. This method is stable and reliable, and has good reproducibility. It is suitable for the analysis of the chemical constituents of volatile oil from Chinese traditional medicine.
