Abstract:A new fluorescent labeling reagent,1,3,5,7-tetramethyl-8-propionohydrazide-difluoroboradiaza-s-indacene(BODIPY-propionohydrazide),was synthesized for the determination of C1-C12 aliphatic aldehydes by high performance liquid chromatography(HPLC).The experimental conditions were optimized.In the presence of phosphorous acid as a catalyst,the derivatization reaction of BODIPY-propionohydrazide with aldehydes was completed in 30 min at 60 ℃.The stable BODIPY hydrazone derivatives(except for formaldehyde and acetaldehyde derivatives) could be separated in 20 min with acetonitrile(containing 20% tetrahydrofuran) and HCOOH-NH3·H2O as mobile phase(pH=6.5).Under the optimal conditions,the calibration curves of C1-C12 aliphatic aldehydes were linear in the range of 0.01-2.00 μmol·L-1 with detection limits(S/N=3) of 0.23-0.78 nmol·L-1.The established method was applied in the determination of aliphatic aldehydes in wine samples with spiked recoveries of 95%-105%.
