Abstract
Process for the preparation of pure hesperetin, characterized in that the commercial grade hesperidin glycoside is subjected to a process of acid hydrolysis, by boiling at reflux in a composition formed by an alcohol, lower 1-3 carbon atoms and 3 n hydrochloric acid, during a period of time of at least 2 hours, after changing the solvent of the hydrolysis and continuing it for two more hours and subsequently the material formed is boiled in an alcohol of 1 to 3 carbon atoms, filtered and evaporated, and finally the concentrated material is precipitates on water, obtaining pure hesperetina.
