Abstract:

Flavonoids are widely distributed in nature, from fruits and vegetables to Chinese materia medica, Most of them have been found to have antibacterial activity, so they are the hot spot in the development of safe and natural preservatives. Plant derived flavonoids exist mostly in the form of glycosides and a few are in the form of free aglycones. As a kind of complex components, the antibacterial properties of plant flavonoids are closely related to the structure, classification and extraction methods of flavonoids. In this review, classification and antibacterial activity of bioactive flavonoids in plants was firstly summarized. Then the antibacterial structure-activity relationship trend of bioactive flavonoids was found by comparing the influence of different structure on the antimicrobial activity of flavonoids. Moreover, the antibacterial mechanisms of flavonoids were elucidated from the whole morphology, normal energy metabolism and inhibition of macromolecular synthesis. Finally, the application of bioactive flavonoids in plants as potential preservative in food, cosmetic and medicine were generalized. The main purpose of this review is to provide theoretical reference for flavonoids as antimicrobial agents.

Key words: flavonoids, natural plant, structure-activity relationship, antibacterial mechanism, application
