Abstract:Tartary buckwheat is rich in flavonoids, such as rutin and quercetin, and their green and efficient extraction is of great significance for resource development and utilization. To promote the development of green extraction technologies for flavonoids from Tartary buckwheat and improve resource utilization efficiency, research progress in conventional extraction methods, novel extraction enhancement technologies, and green solvent systems was systematically reviewed. The extraction principles, process characteristics, advantages, and limitations of different technologies were compared. Conventional extraction methods are well established but are often associated with long extraction times, high energy consumption, and large solvent usage. Emerging technologies, such as ultrasound-assisted, microwave-assisted, and enzyme-assisted extraction, can improve extraction efficiency. Green solvents, including ionic liquids and deep eutectic solvents, show potential for application but still face challenges related to solvent recovery, high costs, and limited scalability. By optimizing extraction technologies and green solvent systems while considering extraction efficiency, energy consumption, solvent safety, and solvent recovery and reuse, this review provides a reference for the green and efficient extraction of flavonoids from Tartary buckwheat.
