Chrysin cocrystals: Characterization and evaluation.

Solvent free mechanochemical approach is utilized to synthesise new cocrystals of chrysin using supramolecular chemistry based upon reliable synthons. Chrysin, a flavone nutraceutical with wide range of beneficial effects has critically low bioavailability on account of its poor aqueous solubility and consequently poor absorption from the gastrointestinal tract. The present study focuses on this critical aspect and has exploited non covalent interactions to prepare its cocrystals with cytosine and thiamine hydrochloride.
