Maize is cultivated in India for grains or as a cereal crop. In maize, the female flowers produce Corn silk, which is generally regarded as a waste and discarded. However, it possesses cosmetic and medicinal values. Corn silk looks like a mass of threads which trap the pollen for pollination. For medicinal purposes corn silk is harvested just before pollination occurs and can be used in fresh or dried form. A greenish fatty oil (2.0-2.5 %) with an agreeable odour is obtained from the stigmas of maize. Corn silk is a waste material from corn cultivation and available in abundance. It contains proteins, phenolic compounds, particularly flavonoids, vitamins, carbohydrates, calcium, potassium, magnesium, sodium salts, volatile oils and steroids such as sitosterol and stigmasterol, alkaloids and saponins. Many flavouring volatile compounds, viz. cis-α-terpinol citronellol, eugenol and neo-iso-3-thujanol are used in perfumery and flavour in soaps, household products and cosmetics.
