Investigation of bioactive compounds and determination of antioxidant potential of corn silk using spectrophotometric methods

Abstract

Corn silks are the yellowish-golden, long, hair-like extensions of the female inflorescence of the maize plant. Even though treated as agricultural waste, corn silks have medicinal uses in certain parts of the world. Acknowledged as a beneficial antioxidant, corn silk has been utilized in combating kidney stones. To reveal the mineral content, a recent work was executed analysing its physicochemical properties. Additionally, phytochemical testing identified the phytoconstituents contributing to its therapeutic benefits and nutritional value. The study found that corn silk had low amount of loss on drying, indicating a good shelf life. Additionally, the phytochemical analysis revealed high amounts of beneficial compounds such as polyphenols, flavonoids, and tannins, suggesting its potential as a rich source of antioxidants. The flavonoids present, responsible for antioxidant properties were quantified and evaluated, further supporting its prospective health benefits. These findings highlight the promising antioxidant potential of corn silk, paving the way for further research and potential applications in the domain of natural antioxidants.
