Abstract: The method for the determination of Thyrotropin-Releasing Hormore in plasma by ion pair RP-HPLC was studied.(column:ODS:mobile phase:0.02mol/1.HAC-acetonitril-sodium 1-heptanesulfonate (89.85:10:0.15):flow rate:1.5ml/min detector:UV 220nm,0.1UFS.The average recovery was 101.69 ± 1.31%. The relation coefficient reached 0.9998.The method was simple and gave correct result and better reproducibility.-
