Abstract

Corn silk (stigma of female flower) is widely exploited for medicinal purposes against various pathogenic microorganisms. The present investigation was carried out to evaluate the antimicrobial and antioxidant properties of corn silk. In this regard, antifungal and antibacterial assays of corn silk extract prepared using microwave assisted method were carried out. The results revealed that corn silk extract possessed better antibacterial potential than antifungal potential. The antifungal assays showed similar results in comparison to positive controls. The antibacterial assays revealed that the plant extract was able to retard the growth of gram positive bacteria better than gram negative bacteria. Highest inhibition zones were observed in case of gram positive bacteria. The free radical scavenging activity of corn silk extract was 50.58% which indicated low phenolics content. The qualitative analysis of the aqueous ethanolic corn silk extract showed positive results for the presence of flavonoids and phenolics.
