Abstract:Headspace solid phase microextraction （HS-SPME）coupled with gas chromatography-mass spectrometry（GC-MS）was established to detect aroma component cedrol in tea.The optimal conditions of HSSPME were determined by optimizing the several factors such as extraction fiber，extraction temperature，extraction time and stirring speed.The results of this study showed that the best extraction and detection efficiency of cedrol were obtained using the extraction fiber of 50/30 μm DVB/CAR/PDMS under the temperature of 80℃ at the rotation rate of 300 r/min for 30 min.Additionally，the recovery rate after standard addition，linear relationship and tea samples analysis were conducted to evaluate the extraction performance of this method，and the results confirmed that this method was highly sensitive and repeatable.
