摘要
本文应用三阶导数分光光度法测定复方天麻口服液中天麻素的含量。以229nm~235nm波长处峰谷间的振幅值作为定量信息,平均回收率为98.72%,RSD为1.07%(n=5)。本法灵敏,结果准确,适用于医院制剂分析。
The quantity of gastrodine in the oral liquid of compound
gastrodia elata was determined by the third derivative UV spec-trophotometry. Amplitude from
peak to valley at wavelengths of 229nm and 235nm was used for calculation.The average
re-covery was 98.7%,the coefficient of variation was 1.07%(n=5).This method is sensitive,the result
is accurate. It is suit- able for analysis of hospital preparation.
