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

Jiang Guozh

Abstract

Objective: 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 was0.075% 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.
