ABSTRACT
OBJECTIVE:
To prepare Hongbei hydrogel and establish its quality control method.METHODS:
Hongbei hydrogel was preparaed using erythomycin and betamethasone as principal agents and carbomer-940 as key base material.The content of erythomycin and betamethasone were determined by UV spectrophotometry at detection wavelength of 483.3 nm and 260 nm,respectively.RESULTS:
The preparation assumed colorless smooth semisolid gel.The linear ranges were 9.69~59.43 ?g?mL-1 for erythomycin (r=0.999 3,n=6) and 6.20~20.27 ?g?mL-1 for betamethasone (r=0.999 5,n=6).The average recovery rate were 98.39% (RSD=1.23%) and 98.24% (RSD=0.43%).CONCLUSION:
The preparation technology was simple,feasible and practical for quality control.
