ABSTRACT

OBJECTIVE:

To establish a method for content determination of cyproheptadine hydrochloride in fuyan cream.

METHODS:

Ultraviolet spectophotometry was applied to determine the contents of cyprohepatadine hydrochloride as well as its adjuvant as two coexisting components without isolation and extraction,the wavelengths were286nm and258nm res_ pectively,linear regression and simultaneous equations were used to analyze the results.

RESULTS:

Cyproheptadine hydrochlor_ ide and its adjuvant showed good linear relationship in the range of2.52~25.2and2.5022~25.022?g/ml respectively,the average recovery of cyproheptadine hydrochloride was98.61%(RSD=1.08%).

CONCLUSION:

The present method is simple,convenient,reproducible and reliable,which is suitable for rapid determination for fuyan cream.
