[Object] The aim was to study the chemical components of essential oil in Buddleia officinalis Maxim and provide the scientific basis for further exploitation and utilization. [Method] The essential oil was extracted by steam distillation. The chemical components of the essential oil were analyzed by GC-MS. The relative contents of these components were calculated using square peaks to normalization. [Result] 46 peaks were separated and 27 components were identified, which were composed of about 72.41% of the total essential oil. [Conclusion] The main components are palmiticacid(14.07%), 6, 10, 14-trimethyl-2-pentadecanone(12.92%), heneicosane(6.15%), and heptacosane(3.28%).
