    [Abstract] Objective To screen the best pretreatment technology of volatile oil inclusion compound. Methods The research on factors and the type of organic solvent， solvent volume， extraction time， the content of cinnamic aldehyde as the score index， inclusion extracted by steam distillation method， through L9(34) orthogonal test， the optimum extraction process. Chromatographic conditions： temperature programmed： 90-180℃； injection volume： 1 μL； split ratio was 50：1. Results The optimum process was the extraction of n-butanol， the volume was 2 mL， and the extraction time was 2 hours. And the volume of solvent had significant influence on this experiment. Conclusion The optimum extraction process is proved to be scientific and feasible ......
