Objective To improve the water solubility of florfenicol, water-soluble florfenicol powder was prepared by inclusion technology with β-cyclodextrin. Methods Taking inclusion rate and the yield of inclusion complex as evaluation indexes, the best inclusion process was screened by orthogonal experiments, the inclusion complex was identified by differential scanning calorimetry analysis(DSC), Fourier transform infra-red spectroscopy(FTIR), scanning electron microscopy(SEM). Results The results showed that the ...
