Several chronic diseases like cancer, diabetes, stroke, neurodegenerative disorders, etc. are rising globally at a faster rate basically due to the increasing free radicals overproduction and oxidative stress from current lifestyle, but can be suppressed or inhibited by antioxidant compounds (Chaturvedi & Beal, 2013;Halliwell, 2012). Now-a-days, the natural antioxidants have a higher demand than the synthetic ones (Kashyap et al., 2017). Among them, flavonoids have a higher value due to their role in human health. They are plantderived compounds having exotic colors which are secondarily produced from phenylalanine (Havsteen, 2002). They are the largest family of naturally occurring polyphenols which include the flavones, flavonols, flavanones, flavanols, isoflavonoids, and anthocyanidins
