In this new HPLC-FLD method, analytes were directly extracted and separated without deriveatization step within 20 min. The FLD wavelength was set at 280 nm and 330 nm for excitation and emission, respectively. The analytes were separated on an Agilent Eclipse Plus Cls column (4.6 mm×150 mm, 5.0 μm) equipped with an Agilent XDB-C18 security guard column (4.6 mm×12.5 mm, 5.0 lam), and the column temperature was maintained at 35 ℃. The mobile phase for elution was isocratic. The mobile phase consisted of citric acid buffer (50 mmol/L citric acid, 50 mmol/L sodium acetate, 0.5 mmol/L octane sulfonic acid sodium salt, 0.5 mmol/L Na2EDTA and 5 mmol/L triethylamine, pH 3.8) and methanol (90:10, v/v) at a flow rate of 1.0 mL/min. The detection limit (DL) was 0.9-23 nM for all the MANTs and their metabolites with a sample volume of 50 μL. The method was shown to be highly reproducible in terms of peak area (intraday, 0.08%-1.85% RSD, n = 5). The simultaneous measurement of these MANTs and their metabolites improved our understanding of the neurochemistry in the central nervous system (CNS) in relation to different addictive drugs (methamphetamine, heroin and their mixture) in drug-addicted rat models.展开更多
