Determination of Jasminoidin in Yinxie Tablets by HPLC / 中国药房

ABSTRACT

OBJECTIVE:To establish a RP-HPLC method for determination of Jasminoidin in Yinxie tablets.METHO_ DSThe HPLC system consisted of C 18 column(250mm?4.6mm,5?m),0.01%phosphoric acid-acetonitrile(87∶13)mixture as a mobile phase,detection wavelength at238nm and1.0ml/min of flow rate.RESULTS:The calibration curve of Jasminoidin was linear in the concentration range of20～200?g/ml(r=0.9995),RSD=0.98%(n=5).The average recovery was101.8%(RSD=0.54%).CONCLUSION:This method is simple,quick and specific,and suitable for the quality control of this prepa?ration.
