Phytochemistry and bioactivity of Citrus flavonoids: a focus on antioxidant, anti-inflammatory, anticancer and cardiovascular protection activities

Epidemiological studies have suggested an inverse relationship between increased consumption of fruits and reduced risk of chronic diseases, such as cardiovascular diseases, cancer, and diabetes. citrus fruit is one of the mostly consumed fruits worldwide, and numerous studies have revealed its remarkable health-promoting activities, such as antioxidant, anticancer, anti-inflammatory, and cardiovascular protection activities. these activities largely depend upon the diverse chemical constituents of citrus fruits, including vitamins, minerals, terpenoids, and flavonoids. notably, dietary flavonoids occurring in citrus fruits have attracted growing interest due to their distinct beneficial effects on human health. in this review, we outlined the main health-related properties of citrus flavonoids, with a focus on antioxidant, anticancer, anti-inflammation, and cardiovascular protection activities. also the bioavailability, a critical factor that influences the biological efficacy, of citrus flavonoids was discussed. it was believed that insights about these advances encourage researchers to discover new phytochemical components and further study specific bioactivities from citrus fruits.
