Study of Quality Control Method for Compound Weilining Nose Drops / 中国药房

ABSTRACT

OBJECTIVE:To establish the quality control method for compound Weilining nose drops.METHODS:First order derivation spectrophotometry was used to determine the content of Weilining in nose drops at wavelength224.7nm.RESULTS:A linearity of concentration(C)and amplitude(D)of Weilining solution was found in range of5～20?g/ml with a regression equation of C=—1.3438+520.78D;(r=0.9998),The average recovery rate was100.35%(n=9),RSD=0.87%.CONCLUSION:The Weilining nose drops is simple in preparation and stable in quality,and this method can be used for quality control of the preparation.
