Abstract:
Objective:To establish UV method for the determination ofcontent of sustained-release droppingpills of oleanolic acid and its dissolution rate.Methods:In 207 nm wavelength,the content of sustained-release dropping pills of oleanolic acid and its dissolution rate were determinated by unico UV-2102PCS.Results:During the determination of the content,the calibration curves was linear in the concentration range of 20～80?g/ml,r=0.9995(n=7),The recovery rate was 98.0%～102%,RSD
