摘　　要：目的:建立芳樟醇的含量测定方法。方法:采用气相色谱外标法,以聚乙二醇(PEG)-20M 和硅酮(OV-17)为固定液的混合柱,柱温为100℃,测定岗松油中芳樟醇的含量。结果:芳樟醇在6.97～34.86μg范围内呈线性关系,低、中、高浓度的平均回收率分别为100.0%,102.1%,105.2%;RSD 分别为3.1%,2.0%,3.7%(n=3)。结论:该方法简便、准确,重复性、回收率好,可作为岗松油中芳樟醇的质量控制方法。Objective：To develop a reliable method for determination of linalool in essential oil from Baeckeafrutescens L. by GC. Method： The external standard method was adopted for determine linalool content in essential oil from Baeckea frutescens I,. Chromatographic assay was performed on a column coated with PEG- 20M and OV -17 mixed stationary phase,the column temperature was 100 ℃. Result： The standard curve was linear in a range of 6. 97-34. 86 μg linalool. The average recovery of assiaticoside were 100.0% ,102. 1% and 105.2% respectively with corresponding RSD of 3. 1% ,2. 0% and 3.7% （ n = 3 ）. Conclusion：The established method is accuracy, sensitive and simple. It can be used to determine linalool of in essential oil from Baeckea frutescens L.
