Objective:Selection ofthe optimal formulation for IL-2 targeting liposome and determination ofcontent for 5-FUR.Methods:orthogonal test method was used to selection the optimal formulation
UV spectrophotometry was used to determine the 5-FUR prodrug content
and the detection wavelength was at 267 nm.Results:The optimal formulation showed Drug/EPC 1∶10
EPC/Ch 3∶1.The absorbency and concentration of 5-FUR prodrug had good linearity in the range of 2.0~20.0μg/mL.The regression equation was y=16.357x+0.007
r= 0.999 7(n=3)
The 5-FUR prodrug content was 18.84~18.91μg/ml.The average recovery rate was 97.09%
and RSD=2.05%(n=3).Conclusion:Formulation was designed reasonablely.The method is simple
stable and reliable
which can be used to determine the 5-FUR prodrug in IL-2 targeting liposome.
