Research progress of flavonoids biological activity

Flavonoids have shown multibiological properties, such as antioxidative activity，freeradical scavenging capacity, coronary heart disease prevention, anticancer activity, antibacterial, prevention of hepatopathy and inhibition (or promotion) of apoptosis. Therefore, Flavonoids have been used to improve the production of livestock. The current advances in flavonoids biological activity was summarized in this paper, which would provide some guidance for researchers in further investigations and in developing animal husbandry healthily.
