A rapid headspace single-drop micro-extraction (mix) gas chromatography mass spectrometry (SDME-GC-MS) for the analysis of the volatile compounds in Herba Asari was developed in this study. A mixed solvent of n-tridecane and butyl acetate (1:1) was finally used for the extraction at 70 ℃ for 15 min with sample amount of 0.750 g and 100 mesh particle size. Under the determined conditions, the pound samples of Herba Asari were directly applied for the analysis. SDME-GC-MS, SPME-GC-MS and SD-GC-MS methods were compared and the results showed that SDME-GC-MS method was a simple, inexpensive and effective way to measure the volatile compounds in Herba Asari and could be used for the analysis of volatile compounds in complex samples.
