A rapid headspace single-drop micro-extraction(mix) gas chromatography mass spectrometry(SDMEGC -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 C 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-GCMS 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.
A rapid headspace single-drop micro-extraction (mix) gas chromatography mass spectrometry (SDMEGC -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) was finally used for the extraction at 70 C for 15 min with a sample amount of 0.750 g and 100 mesh particle size. Undetermined conditions, the pound samples of Herba Asari were directly applied for the analysis. SDE-GC-MS, SPME-GC-MS and SD-GCMS 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.
