چکیده
|
A rapid headspace single-drop microextraction gas chromatography mass spectrometry (sdme-gc-ms) for the analysis of the volatile compounds in herba asari was developed in this study. the extraction solvent,extraction temperature and time,sample amount,and particle size were optimized. a mixed solvent of n-tridecane and butyl acetate (1: 1) was finally used for the extraction with sample amount of 0.750 g and 100-mesh particle size at 70°c for 15 min. under the determined conditions,the pound samples of herba asari were directly applied for the analysis. the result showed that sdme-gc-ms method was a simple,effective,and inexpensive way to measure the volatile compounds in herba asari and could be used for the analysis of volatile compounds in chinese medicine. © 2013 guan-jie wang et al.
