摘要
本文报道用等导数值光谱法测定寒热痹胶囊中麻黄碱的含量。结果表明,该法操作简便、灵敏度高,重现性好。线性范围为0.08～0.48mg/ml,平均回收率为100.4%,变异系数为0.39%.
In the quantitative determination of Ephedrine Hydrochloride in capsulae Han Re Bi Equivalent Derivate Spectrometry proved simpe, rapid, sensitive and repeatabe. Under the given experimental conditions the calibration curves were linear within the concentration range of 0.08～0.48mg/ml, the average recovery being 100.4% and coefficient of variation 0.39%.
