Abstract:
1. A resveratrol and cyclodextrin compound complex produced from a process comprising the steps of: a) completely homogenizing β-cyclodextrin in water with heating from 50 to 80° C., up to a β-cyclodextrin concentration lower than or equal to 60 mM; b) adding, to the solution resulting from step (a), a water miscible and physiologically acceptable organic solvent, up to an organic solvent:water ratio ranging from 1:1 to 1:5; c) adding, to the mixture resulting from step (b), a solution of a trans-resveratrol compound diluted in a water miscible and physiologically acceptable organic solvent, and heating the resulting mixture at a temperature range from 50 to 80° C.; d) cooling slowly the solution resulting from step (c) until precipitation from the mixture of crystals of the resveratrol and cyclodextrin compound complex; and e) separating out the crystals of the resveratrol and cyclodextrin compound complex, wherein the resveratrol and cyclodextrin compound complex is in a solid crystalline form and has a solubility of about 3010 mg/L in water.
