摘要
实验建立了紫外分光光度法测定延胡索酸泰妙菌素预混剂的含量。实验结果表明,延胡索酸泰妙菌素的最大吸收波长为202nm,在此波长处,延胡索酸泰妙菌素在2.5～15.0μg/mL浓度范围内,其吸光度与浓度呈现良好的线性关系：A=0.0271c＋0.0521,r2=0.9999（n=6）。该方法操作简单、测定快速,结果准确,可用于延胡索酸泰妙菌素预混剂的含量测定。
An ultraviolet spectrophotometric determination method of tiamulin fumarate premix was establisked.The experimental results showed that the maximum absorption wavelength of tiamulin fumarate was 202nm,and the linearity of the tiamulin fumarate concentration curve was good in the range of 2.5～15.0μg/mL.The regression equation was A=0.0271c＋0.0521,R2=0.9999（n=6）.The method is simple and quick,and the result is reliable.It can be applied to quick determination of tiamulin fumarate premix.
