Evaluation of antioxidant and antimicrobial potential of mango seed kernel

Abstract

The present study evaluated the antioxidant and antimicrobial activity of mango seed kernel extracts prepared in different extraction solvents. Three different solvents viz. acetone, methanol, and water were used to extract the bioactive compounds of mango seed kernel and their antioxidant potential was estimated using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2-azinobis 3 –ethylbenzothiazoline-6-sulfonic acid (ABTS) scavenging assays. The results revealed that methanolic extract of mango seed kernel showed higher antioxidant activities than acetonic and water extracts. Based on the higher antioxidant potential, methanolic extract of mango seed kernel was further assessed for antimicrobial activity against selected bacterial species namely Xanthomonas campestris and Escherichia coli using well diffusion method. This research shows that mango seed kernel is an abundant and cost-effective source of potential natural antioxidant and this would probably become an alternative source of antimicrobial agents.
