Retracted: Preparation and Biological Availability of Resveratrol Nanoparticles

Objective: Preparation of nanoparticles of resveratrol, prepared under different carriers resveratrol nanoparticles and study its inhibitory effect on HepG2 hepatoma cell line. Method: in ethylene glycol test solution add and 0.1% stannous octoate, under vacuum conditions in a closed polymerization tube, for 40 hours in an oil bath, the reaction temperature was 130¡æ. Sample solution was dissolved in chloroform to obtain a precipitate, With methanol to remove impurities, the preparation of mPEG-PCL diblock polymer. Use 20mg mPEG-PCL and 4mg Res dissolved in 3ml acetone. While stirring, dispersed in 20ml of distilled water was added poloxamer-188, the solution was placed in dialysis bags and dialyzed 12kd use 220nm membrane, the polymer aggregates was filtered off, formed nanoparticles.
