Traditional flavonoid extraction techniques are being replaced by advanced techniques to reduce energy and solvent consumption, increase efficiency and selectivity, to meet increased market demand and environmental regulations. Advanced technologies, such as microwaves, ultrasound, pressurized liquids, supercritical fluids, and electric fields, are alternatives currently being used. These modern techniques are generally faster, more environmentally friendly, and with higher automation levels compared to conventional extraction techniques. This review will discuss the different methods available for flavonoid extraction from natural sources and the main parameters involved (temperature, solvent, sample quantity, extraction time, among others). Recent trends and their industrial importance are also discussed in detail, providing insight into their potential. Thus, this paper seeks to review the innovations of compound extraction techniques, presenting in each of them their advantages and disadvantages, trying to offer a broader scope in the understanding of flavonoid extraction from different plant matrices.}, publisher = {FRONTIERS MEDIA SA}, keywords = {flavonoids}, keywords = {natural products}, keywords = {extraction}, keywords = {sample preparation}, keywords = {modern techniques}, title = {Extraction of Flavonoids From Natural Sources Using Modern Techniques}, doi = {10.3389/fchem.2020.507887}, author = {Oliveira Chaves, Jaísa and Corrêa de Souza, Mariana and Capelasso da Silva, Laise and Lachos-Perez, Daniel and Torres-Mayanga, Paulo César and da Fonseca Machado, Ana Paula and Forster-Carneiro, Tânia and Vázquez Espinosa, Mercedes and Velasco González de Peredo, Ana and Fernández Barbero, Gerardo and Rostagno, Mauricio Ariel}, }
