Abstract
A spectrophotometric method of assay of mefenamic acid in tablets involving, dissolving the tablet powder in 1,4-dioxane and measuring the absorbance at 353.2 nm. The concentration of mefenamic acid is determined using the previously prepared calibration curve using standard solution of mefenamic acid in dioxane. The method was tested by assay of six different commercial tablets containing mefenamic acid.
摘要
一种分光光度法测定片剂中甲芬那酸的方法，该方法包括将片剂粉末溶解于1,4 - 二氧六环中，并在353.2 nm处测量吸光度。甲芬那酸的浓度通过使用先前制备的甲芬那酸在二氧六环中的标准溶液校准曲线来测定。该方法通过测定六种不同的含甲芬那酸市售片剂进行了测试。
