title: [Determination of megestrol acetate and estradiol valerate in injection of microencapsulated compound megestrol acetate by secondary derivative spectrophotometry].
abstract: The paper reports the simultaneous determination of megestrol acetate and estradiol valerate in the injection of microencapsulated compound megestrol acetate by secondary derivative spectrophotometry. The experimental results showed that the average recoveries of the two drugs were 98.8% and 98.0%, respectively, and that the coefficients of variation were 0.71% and 1.81%, respectively.
