Abstract:

Florfenicol-hydroxypropyl-β-cyclodextrin was prepared by colloid mill technique using orthogonal experiment technology to improve its solubility. The inclusion rate and getting ratio of the complex were taken as indexes to analyze the effect. The optimum preparation procedure was the proportion of 1:1 for HP-β-CD to florfenicol, the concentration was 6 mg/mL and the time was 1 h. Its structure was proved by DSC and IR, which suggested that the florfenicol was wrapped by HP-β-CD. The inclusion rate was 83.74% and the getting ratio was 98.48%. The solubility of florfenicol was increased from 1.25 mg/mL to 40.76 mg/mL.Thus, it showed that the process was suitable for batch preparation of florfenicol-hydroxypropyl-β-cyclodextrin inclusion complex.

Key words: florfenicol; hydroxypropyl-β-cyclodextrin; inclusion complex; solubility; orthogonal experiment
