Abstract:: The volatile oils was extracted by steam distillation method and gas liquid phase continual extraction method from Lilium longiflorum and by gas chromatography mass spectrometry(GC-MS) were analyzed.Finally the area normalization was used to measure the relative percentages of each of the components.The results showed that 57 components were separated and 52 components were identified.The main components were alkene,alcohol,ester,aldehyde,acid and alkane series.compared with steam distillation method,more than 14 components with lower boiling points and small relative molecular mass were extracted by gas liquid phase continual extraction method.The relative percentages were higher of lower boiling points components by gas liquid phase continual extraction method,for example：p-menth-1-en-8-ol(0.40%,3.49%),(E)-3,7-dimethyl-2,6-Octadien-1-ol(0.35%,2.60%),3,7,11-trimethyl-1,6,10-Dodecatrien-3-ol（10.40%,19.76%）.
