Ultrasonic nebulization extraction (UNE) combined with headspace single-drop microextraction (HS-SDME) and gas chromatography–mass spectrometry (GC–MS) have been used for rapid analysis of volatile components of the pericarp of Zanthoxylum bungeanum Maxim. Effective extraction was achieved by suspending 2 μL n-heptadecane from the tip of a microsyringe, extracting for 15 min, and enriching for 25 min...
A novel method for analysis of essential oil in Cuminum cyminum L. using simultaneous ultrasonic nebulization extraction and headspace single drop microextraction (UNE–HS-SDME) followed by gas chromatography–mass spectrometry was developed. Experimental parameters, including the kind of suspended solvent, microdrop volume, sample amount, extraction time, enrichment time and salt concentration were...
