Abstract

A sustainable, reagent-less and one-pot ultrasonic methodology has been developed to transform amorphous tannic acid into regularly shaped crystalline ellagic acid particles. Multiple and consecutive reactions have been performed on tannic acid, in aqueous solution without the addition of any external reagent. The size, morphology and bio-activity of ellagic acid micro-nanocrystals can be finely tuned by choosing appropriate ultrasonic parameters.
