Determination of Mentha spicata in Chuanbei Qingfei Syrup based on GC-MS analysis
Objective To establish a gas chromatography method for the determination of Mentha spicata in Chuanbei Qingfei Syrup.Methods A capillary column with 5％diphenyl-95％dimethyl polysiloxane stationary phase and a hydrogen flame ionization detector were used for detection.The initial temperature of the column was 70 ℃,kept for 4 min,then increased to 120℃ at the rate of 1.5℃/min,to 200℃ at the rate of 3℃/min,to 230℃ at the rate of 30℃/min,and finally kept for 2 min.Results This method was able to detect the characteristic component carvone in Mentha spicata and detect positive samples,which were confirmed by gas chromatography-mass spectrometry(GC-MS).Conclusion This method can be used to detect the presence of Mentha spicata in Chuanbei Qingfei Syrup,reflect the production and feeding of mint,and provide assistance for regulating drug production and quality.
