Preparation and Characterization of Gossypol Nanosuspensions


Article Preview

Gossypol (GP) is a kind of poorly water-soluble polyphenolic compounds. In this study, freeze dried gossypol nanosuspensions (GP-NS) were prepared by high-pressure homogenization and Freeze-drying technique. Bovine serum albumin (BSA) and D-alpha-tocopheryl polyethylene glycol succinate (TPGS) were used as stabilizing agents for the nanosuspensions while mannitol were used as lyophilized protecting medium. The physicochemical characteristics of the GP-NS were investigated when it was found that the mean particle size and zeta potential of the GP-NS were 217±23 nm and-21.4±2.7 mV, respectively, and the saturation solubility was 586.48±23.03 μg.mL-1. Differential scanning calorimetry and X-Ray Diffraction indicated that GP was in a crystalline state in nanosuspensions. GP-NS with a small particle size, and high saturation solubility, can be produced by the method described in this study.
