A green method for anthocyanin extraction from Clitoria ternatea flowers cultivated in southern Brazil: Characterization, in vivo toxicity, and biological activity.

This study aimed to develop a green method to obtain an anthocyanin-rich edible extract of Clitoria ternatea flowers grown in southern Brazil. The extract was characterized by UHPLC-MS and analyzed for toxicological potential in an in vivo model, total phenolic content, and biological activities. By using a 2 multivariate design to study the effects of temperature, acidified solvent, and time on the total anthocyanin content (487.
