摘要	A new fluorescence reagent 2-(2-(4-(dimethylamino)-phenyl)-1H-phenanthro-[9,10-d]- imidazol-1-yl)-ethyl-4-methylbenzenesulfonate (PPMB) has been designed for fatty acids labeling. Fifteen fatty acids containing six saturated and nine unsaturated fatty acids were used to evaluate the analytical potential of this reagent. The derivatization reaction of PPMB with fatty acids was carried out in the presence of K2CO3 catalyst at 95 degrees C for 40min in N, N-dimethylformamide solvent. The separation of fatty acids was achieved on a reversed-phase Hypersil BDS C-8 column (4.6x200mm, 5 mu m) with a good baseline resolution. The fluorescence excitation and emission wavelengths were set at (ex) 260nm and (em) 430nm, respectively. The identification was carried out by the online APCI-MS in positive-ion detection mode. Results showed the fatty acid derivatives not only enabled sensitive fluorescence detection but also had high MS ionizability. Excellent linear responses were observed using fluorescent detection with coefficients of >0.9993. Detection limits, at a signal-to-noise ratio of 3:1, were in the range of 29.88-69.37 fmol. Fatty acid extracts from Lycium chinese mill, Long pepper, and Evodiae fructus were successfully analyzed with satisfactory results.; A new fluorescence reagent 2-(2-(4-(dimethylamino)-phenyl)-1H-phenanthro-[9,10-d]- imidazol-1-yl)-ethyl-4-methylbenzenesulfonate (PPMB) has been designed for fatty acids labeling.
