Abstract：In order to optimize the quantitative determination of low concentration clenbuterol from the food of animal origin, a immunochromatography detection system was set up using gold magnetic nanoparticles as supports. The results showed that the standard curves of clenbuterol (CLB) and rctopamine (RAC) test trips were between 0.5～50 ng/mL and 1.0～100 ng/mL, respectively. The lower limits of detection (LLOD) were 0.25 ng/mL and 0.5 ng/mL.CLB and RAC react negatively with drugs of same kind. The recovery rate is between 82.71 and 104.12 ％, which means the accuracy meets the requirements. Coefficient of variation (CV) is lower than 15 ％ with different CLB and RAC adding level, which means the the precision meets the requirements. The false positive rate and false negative rate were both 0.This method shows high sensitivity, stability and specificity for CLB and RAC detection.
