采用二阶导数分光光度法测定口服乳剂中替加氟的含量。在波长２９０～２９３ ｎｍ 范围内辅料对测定均无干扰，在２６～８２ μｇ／ｍ ｌ浓度范围内振幅Ｄ 与浓度具有良好的线性关系。平均回收率９９．８６％ ，ＲＳＤ为０．２４％ ，方法简便，结果准确
Determination of tegafur in oral emulsion by second derivative spectrophotometry. In the wavelength range of 290 ~ 293 nm accessories for the determination of no interference, in the concentration range of 26 ~ 82 μg / m l amplitude D and the concentration has a good linear relationship. The average recovery was 99.86% with RSD of 0.24%. The method was simple and the result was accurate
