    Abstract:
    OBJECTIVE: To study the pharmacokinetics characteristics of six Aconitum alkaloids aconitine (AC), mesaconitine (MA), hypaconitine (HA), benzoylaconine (BAC), benzoylmesaconine (BMA) and benzoylhypaconine (BHA) in beagle dogs. METHODS: An ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method was developed for simultaneous quantitation of six Aconitum alkaloids in beagle dog plasma after oral administration of Aconiti Lateralis Radix Praeparata decoction. UPLC/MS/MS system coupled with an electrospray ionization (ESI) source was performed in multiple-reaction monitoring (MRM) mode. Sample preparation was performed with solid-phase extraction(SPE) on a 3 mL HLB cartridge before the analysis. The separation was applied on a Waters C8 column (100 mm x 2.1 mm, 1.7 microm) and a gradient elution of methanol and 0.2% formic acid-water was used as mobile phase. The pharmacokinetic parameters were calculated by the results of the analysis through the DAS 2. 1 software (Drug and Statistics for Windows). RESULTS: The results showed that the fitting model for the six Aconitum alkaloids was the one-compartment model pharmacokinetics. CONCLUSION: The method is successfully used for the pharmacokinetic evaluation of the six Aconitum alkaloids in beagle dog plasma, it can help monitor the ADME/Tox process when taking Aconiti Lateralis Radix Praeparata by observing the pharmacokinetic process. The results provide a good reference for clinical treatment and safe application of Aconiti Lateralis Radix Praeparata.
