ABSTRACT
OBJECTIVE:
To establish a HPLC method for the determination of oxymatrine(OMT)and matrine(MT)in dog plasma.METHODS:
Plasma protein was precipitated with perchloric acid;OMT and MT were extracted with dichloromethane under strong base condition and then plasma levels of OMT and MT were determined by HPLC.RESULTS:
The linear ranges of OMT and MT were 0.2~ 15? g? mL-1 and 0.1~ 5? g? mL-1,respectively,and the detection limits of OMT and MT were 20ng? mL-1.The absolute recoveries,relative recoveries,intra-day and inter-day precisions of OMT and MT were all in line with the standards.CONCLUSION:
The method is simple,accurate and sensitive yet with little interference,and it is applicable for the determination of OMT and MT in plasma,the studying of the pharmacokinetics,the transformation process and the metabolic pathway of OMT in vivo,furthermore,it serves as guidance for the development of new OMT preparations.
