Content Determination of Eucalyptol and Camphene in Galangal Formula Granules by GC-MS

目的:利用GC-MS联用技术分析高良姜配方颗粒中桉叶油醇和莰烯含量。方法:用水蒸汽蒸馏法从高良姜配方颗粒中提取挥发油,经气质分析仪分析,NIST08库定性分析桉叶油醇和莰烯,用外标法定量。结果:桉叶油醇含量0.075%,相对偏差5.4%,莰烯含量0.018%,相对偏差6.6%。结论:此方法稳定、可靠,重现性好,适用于高良姜配方颗粒中桉叶油醇和莰烯含量的分析。

To analyze the content of eucalyptol and camphene in galangal formula granules by GC-MS. Methods： Volatile oil was extracted from galangal formula granules by steam distillation method. Qualitative analysis of eucalyptol and camphene was carried out by using GC-MS and NIST08, the mass spectra library. External standard method was adopted for quantification. Results： The content percentage of eucalyptol was 0.075% and the relative deviation was 5.4%. The percentage of the content of camphene was 0.018% and the relative deviation was 6.6%. Conclusion： This method is stable, reliable and has good reproducibility so that it is suitable for the analysis of the content of eucalyptol and camphene in galangal formula granules.
