ABSTRACT
Plant-derived functional foods are gaining considerable attention due to their safety and therapeutic potentials. Research on plant-based functional foods presents several challenges ranges from hypercholesterolemia to cancer prevention. In last decade, special attention has been paid to edible plants and especially their phytochemicals. Today, there is an increasing interest in their bioactivities provided by these phytochemicals. Polyphenols are the most numerous and widely distributed group of bioactive molecules. Polyphenols have two general classes, one is flavonoids and other is phenolic acids. Among these, flavonoids are further divided into flavones, flavononse, flavonols, flavanols, isoflavones, and phenolic acids are generally classified into hydroxybenzoic and hydroxycinnamic acids. Fruit peel is one of the dense sources for flavonoids and their content may vary from species to species and due to exposure of light. Polyphenols have wide range of molecules and different set of biological activities that are mainly attributed to their structure. Investigations have revealed that polyphenols play a key role to prevent various diseases, like hypercholesterolemia, hyperglycemia, hyperlipidemia, and cancer insurgence. The current review article summarizes the literature pertaining to polyphenols and its allied health benefits.
