Abstract: A method for the determination of volatile compounds in Pueraria Radix by headspace solid-phase microextraction (HS-SPME)-gas chromatography-mass spectrometry (GC-MS) combined with the automatic deconvolution software automated mass spectral deconvolution and identification system (AMDIS) was established. Total peak area and number of peaks were used as response variables to optimize the extraction conditions of HS-SPME by one-factor-at-atime and orthogonal array design methods. The results showed that the extraction conditions were optimized as follows: 3.0 g of sample, equilibration time 13 min, extraction for 50 min at 90 ℃ using 50/30 μm DVB/CAR/PDMS fiber and then desorption for 5 min. Under these conditions, 67 volatile components were identified, including 11 esters, 22 aldehydes, 9 alcohols, 5 ketones, 8 terpenes, and 12 others.
