In this method, <jats:italic>O<\/jats:italic>\u20102,3,4,5,6\u2010(pentafluorobenzyl)hydroxylamine (PFBHA) in aqueous solution was first headspace adsorbed onto a 65 \u03bcm poly(dimethylsiloxane)\/divinylbenzene (PDMS\/DVB) fiber at 25\u00b0C for 5 min, and then the fiber with adsorbed PFBHA was used for headspace extraction of tomato plant emission at 25\u00b0C for 6 min. Finally, the resulting oximes adsorbed on the fiber were desorbed and analyzed by GC\u2010MS. Extraction conditions and method validation were studied. The proposed method had low detection limit values for the three aldehydes from 0.1 to 0.5 ng\/L and good precision (RSD less than 10%).
