Objective: To establish a method for assay of homocysteine in rats plasma with High Performance Liquid Chromatography and Electrochemical Detector. Methods: Plasma homocysteine was reduced by dithiothreitol
separated on reverse phase ODS2 column with 10% methanol mobile phase and detected on ESA 5600 electrochemical detector. Results: The method showed excellent linearity over the concentration range 0.1~100 μmol·L-1 of Hcy (r=0.999 3
n=7). The recoveries of analytes were from 96.79 %~104.40 %. The precisions
and the stability of the analytes meet the requirements. Conclusion: The established method show high sensitivity and good reproducibility
which make it suitable to determine Hcy level in rats plasma.
