摘  要:目的 建立吲哚美辛的紫外分光光度法,并用于吲哚美辛片中吲哚美辛含量及肠溶片释放度的测定.方法 采用紫外分光光度法,以磷酸盐缓冲液(pH7.2)-甲醇(1:1)为溶剂,最大吸收波长320 nm.结果 吲哚美辛标准品溶液在10 -35 μg/ml的浓度范围内,A=0.0195C+0.0554(μg/ml)线性关系良好,相关系数为0.9995(n=6);样品在7h内稳定,RSD%为0.25%;平均回收率分别为95.96%,96.85%,98.82%,RSD分别为0.31%,0.36%,0.15%.结论 该含量测定方法准确,快速,简单,可靠,可用于吲哚美辛片含量及肠溶片释放度的测定,较适用于生产过程中的质量控制.Objective : To establish a Uv - vis method for Indom - metacin, and apply it into the determin of release ratelof Indom metacin Enteric - coated Tablets. Method: Adopting Uv - vis phosphate buffer solution (Ph7.2) - alcohl( 1:1 )as dissolvant to determin its absorbance at the biggest assimilate wavelength. Resuhs:Indom metacin's standard substancedissolvent in the 10 - 35 ixg/ml concentration renge , A = 0. 0195 C + 0. 0554 (i.tg/ml) ( r = 0. 9995 ) good liner ralation. Thesample will be stabilization in 7h ( RSD = 0.25% ), the average of Indom metacin Enteric - coated Tablets ( rt = 6 ) were95.96% (RSD = 0.31% ) ,98.85% ( RSD = 0. 36% ) ,98.82% ( RSD = 0. 15% ). Conclusion: The method is accurate ,convienent, sensitive and reliable with high reproducibility and used for content determination of release ratel of Indommetacin Enteric -coated Tablets and management control in the productive process.
