High Performance Liquid Chromatography with Electrochemical Detector for the Determination of Monoamines and Their Metabolites in the Spinal Perfusate of Rat |
| |
| Abstract: | A method for the separation and determination of monoamine transmitters and their metabolites in the spinal perfusate of rat was developed by RP HPLC with electrochemical detector.When the perfusion speed was set at 1.0mL/30min,and the samples were collected successively every 30min for 90min,the contents of three kinds of monoamine's metabolites were stable in the spinal perfusate,which proved that using spinal perfusion system coupled with HPLC to study the physiological function of monoamine in the spinal cord was practical and reliable. |
