Phenolic compounds are the secondary metabolites synthesized in plants. Basically in chemical composition it is a heterogeneous molecule with phenol group in its basic structure. Polyphenols exists in various forms like simple molecules to polymerized structures like phenolic acids to tannins respectively. The major phenolic compounds were phenolic acids, flavonoids and anthocyanins.
