摘要
目的:建立测定盐酸依匹斯汀片中主药含量的紫外分光光度法。方法:采用紫外分光光度法检测盐酸依匹斯汀片含量,检测波长为262nm。结果:盐酸依匹斯汀检测浓度线性范围为5.0～30μg.mL-1(r=0.9999);平均回收率为99.65%,RSD=0.27%。结论:所建立的检测方法稳定性及重现性好,能够有效控制盐酸依匹斯汀片的质量。
OBJECTIVE： To establish a UV spectrophotometry method for determining the content of main component in epinastine hydrochloride tablets. METHODS： The content of epinastine hydrochloride was determined by UV spectrophotometry with a detection wavelength of 262 nm. RESULTS： The linear range of epinastine hydrochloride was 5.0--30μg·mL^-1 （r = 0.999 9） and the average recovery rate was 99.65% （RSD =0.27% ） . CONCLUSION： The method is stable and reproducible, and it can be used for an effective quality control of epinastine hydrochloride tablet.
