Good nutrition plays.a crucial role in maintaining a balanced lifes.yle. The beneficial effects.of nutrition have been found to counteract nutritional dis.urbances.with the expanded us. of nutraceuticals.to treat and manage cardiovas.ular dis.as.s. cancer, and other developmental defects.over the las. decade. Flavonoids.are found abundantly in plant-derived foods.s.ch as.fruits. vegetables. tea, cocoa, and wine. Fruits.and vegetables.contain phytochemicals.like flavonoids. phenolics. alkaloids. s.ponins. and terpenoids. Flavonoids.can act as.anti-inflammatory, anti-allergic, anti-microbial(antibacterial, antifungal, and antiviral) antioxidant, anti-cancer, and anti-diarrheal agents. Flavonoids.are als. reported to upregulate apoptotic activity in s.veral cancers.s.ch as.hepatic, pancreatic, breas., es.phageal, and colon. Myricetin is.a flavonol which is.naturally pres.nt in fruits.and vegetables.and has.s.own pos.ible nutraceutical value. Myricetin has.been portrayed as.a potent nutraceutical that may protect agains. cancer. The focus.of the pres.nt review is.to pres.nt an updated account of s.udies.demons.rating the anticancer potential of myricetin and the molecular mechanis.s.involved therein. A better unders.anding of the molecular mechanis.(s. underlying its.anticancer activity would eventually help in its.development as.a novel anticancer nutraceutical having minimal s.de effects.
