Polyphenols are secondary metabolite of the plants and contains more than one phenolic group in their structure. Polyphenols compounds are important for plants as they impart color, flavors and tastes to many plants. Polyphenols include several thousand compounds, among them the flavonoids, flavones, catechins, flavanones, anthrocyanidines and isoflavonoids are important. Polyphenols are antioxidant molecules and neutralize harmful free radicals and prevent oxidative stress, which damage cells and DNA. Polyphenols are important antioxidants molecules which are used in preventing the diseases like cancer, cardiovascular, neuro diseases, inflammation, high blood pressure, cholesterol increase. Researchers have shown that polyphenols can be extracted from citrus fruits peels by using different solvents and different extraction conditions. Antioxidant property is proportional to the Polyphenols concentration present in the sample. It has been reported by research paternity that the polyphenols thus extracted can be used to treat the degenerative diseases. As per the market estimation, the global polyphenols market reach to a total consumption of 21,032.7 tons by the end of 2018. Polyphenol industry faces key challenges like sourcing and supply chain quality. These challenges are multiplying due to increased pressure on land for agriculture and development, the investment in sustainable supply chain and research is focused on finding out the exact class of plant for production . Market study very clearly indicates the importance of research on extracting polyphenols in an economically feasible way and if it could be from the natural resources the advantage will be doubled and a ecofriendly way will make the extraction from the fruits waste best way forward for polyphenols.
