Abstract

The Cymbopogon jwarancusa (Jones.) leaves extracts were explored for their antioxidant and antimicrobial activity. The ethanol extract showed highest antioxidant activity in DPPH (31.99 ± 0.50 % inhibition) and FRAP (38.79 ± 0.54 Fe (II) micromole per litre) assay while water extract showed highest antioxidant activity in ßCL (54.76 ± 1.37 %) at 1mg/10ml concentration. BHT and ascorbic acid were used as standards. During antimicrobial assay, the ethanol extract found was very effective against Fusarium oxyporium f.sp-lini (85.31 ± 0.25 mm) and Staphylococcus aureus (94.37 ± 0.28 mm) at 500 ppm while water extract was found less effective against Aspergillus flavus (03.72 ± 0.19 mm) at 100 ppm concentration. The ethanol extract can be used for the applications such as food preservation as a remedy and against dental diseases.
