摘　　要：采用紫外分光光度法测定饲料预混剂中磷酸泰乐菌素的含量。试验结果表明,磷酸泰乐菌素的的最大吸收波长为289nm,在此波长处,磷酸泰乐菌素的质量浓度在5.0～50.0μg/ml,其吸光度与质量浓度呈现良好的线性关系:A=0.026 9x+0.028 6,R2=0.999 9(n=6)。该方法操作简单快速,结果准确,可用于饲料预混剂中磷酸泰乐菌素含量的测定。The tylosin phosphate in feed premix was determined by ultraviolet spectrophotometry. The experiment results showed that：the maximum absorption wavelength o{ tylosin phosphate was 289 nm, and the linearity of absorption was good with concentration in the range of 5.0-50.0 μg/ml. The regression equation was：A=0. 026 9x＋0. 028 6,R2 =0. 999 9（n= 6）. The method was simple and quick, and accurate, which could be applied into quick determination of tylosin phosphate in feed premix.
