Corn silks are yellowish-golden, long, hair-like extensions of the female inflorescence of the maize plant. Even though treated as an agricultural waste, corn silk has been used as medicine in certain parts of the world. It is widely acknowledged for its antioxidant benefits and consumed in the form of corn silk tea. Present study on corn silk revealed low amount of loss on drying, indicating a good shelf life, an essential parameter for valorisation of corn silk. Phytochemical analysis revealed high amounts of secondary metabolites, polyphenols and flavonoids, suggesting its potential as a rich source of antioxidants. Total polyphenols in YCS extract were measured to be 1.35 mg GAE/g, and WCS extract contained 4.51 mg GAE/g of powdered corn silk. Total flavonoids in YCS extract were found to be 0.19 mg QE/g whereas WCS extract had 1.67 mg QE/g. Amount of vitamin C in YCS extract was 44.2 μg AAE/g, while WCS showed 566 μg AAE/g. In DPPH assay, YCS extract showed an inhibition percentage of 50.96%, whereas the WCS extract exhibited a higher percentage of 90.99%. These findings highlight the promising antioxidant potential of corn silk, paving the way for synthesis of value-added products and their potential applications in the domain of natural antioxidants.
