QUICK METHOD FOR DETERMINING IN ULTRA TRACES AROMA COMPOUNDS () FROM AROMATIC PLANT SAMPLES BY ULTRASONIC EXTRACTION AND GAS CHROMATOGRAPHY COUPLED WITH MASS SPECTROMETRY ()

摘要

The invention relates to an analytic method for determining aroma compounds in aromatic plant samples. According to the invention, the method comprises the ultrasound extraction from aromatic plant samples with a solvent mixture methanol:dichloromethane:n-hexane in a volume ratio of 3:2:1, at a temperature of 30...60°C for 15...30 min, followed by the evaporation of the extract and the simultaneous determination of 22 analytes by gas chromatographic analysis coupled with mass spectrometry.
