中文摘要	a sensitive and efficient method for simultaneous determination of glutamic acid (glu), gamma-amino-butyric acid (gaba), dopamine (da), 5-hydroxytryptamine (5-ht) and 5-hydroxyindole acetic acid (5-hiaa) in rat endbrains was developed by high-performance liquid chromatography (hplc) with fluorescence detection and on-line mass spectrometric identification following derivatization with 1,2-benzo-3,4-dihydrocarbazole-9-ethyl chloroformate (bceoc). different parameters which influenced derivatization and separation were optimized. the complete separation of five neurotransmitter (nt) derivatives was performed on a reversed-phase hypersil bds-c-18 column with a gradient elution. the rapid structure identification of five neurotransmitter derivatives was carried out by on-line mass spectrometry with electrospray ionization (esi) source in positive ion mode, and the bceoc-labeled derivatives were characterized by easy-to-interpret mass spectra. stability of derivatives, repeatability, precision and accuracy were evaluated and the results were excellent for efficient hplc analysis. the quantitative linear range of five neurotransmitters were 2.441-2 x 10(4) nm, and limits of detection were in the range of 0.398-1.258 nm (s/n = 3:1). the changes of their concentrations in endbrains of three rat groups were also studied using this hplc fluorescence detection method. the results indicated that exhausting exercise could obviously influence the concentrations of neurotransmitters in rat endbrains. the established method exhibited excellent validity, high sensitivity and convenience, and provided a new technique for simultaneous analysis of monoamine and amino acid neurotransmitters in rat brain.
