摘要： Palmatine is an isoquinoline alkaloid isolated from many medicinal plants with diverse pharmacological activities, with potential for the treatment of chronic metabolic disorders and infectious diseases. In the present study, a highly rapid, simple, and sensitive ultra-performance liquid chromatography coupled with an ultra-violet (UPLC-UV) method was developed and validated for the pharmacokinetics and tissue distribution of palmatine following single intramuscular injection to Partridge Shank chickens. The process was sensitive, with a lower limit of quantification and good linearity over the range of 0.005-10 mu g/mL for UPLC-UV in all biological matrices. Following a single intramuscular dose of 5 mg/kg b.w, palmatine was absorbed quickly and reached peak concentration (0.24 mu g/mL) at 0.19 h and was still present in plasma at 12 h with a concentration of 0.011 mu g/mL. The CL/F and Vd/F were 10.43 Lh(-1)kg (-1) and 56.69 L/kg, respectively. The C-max values of palmatine in tissues decreased as follows: kidneys > liver > spleen > heart > lung > muscles, and were almost completely cleared from lungs 26 h after administration and were not detectable or significantly reduced in other tissues after 48 h. The results can provide a basis for exploring the therapeutic potential of palmatine and looking for new ways of wide clinical applications in poultry farming.
