Antioxidant Activity and Trace Elements Profile of Extracts of Cymbopogon jwarancusa (Jones.) leaves

Abstract

This research paper report the antioxidant activity and trace element analysis of Cymbopogon jwarancusa (Jones.). The ethanol extract showed highest antioxidant activity in DPPH (32.08 ± 0.53 % inhibition) and FRAP (39.01 ± 0.64 Fe (II) micromole per litre) assay while water extract showed highest antioxidant activity in I²CL (54.26 ± 1.09 %) at 1mg/10ml concentration. BHT and ascorbic acid were used as standards. Trace elements analysis showed sodium (Na+) 0.08%, potassium (K+) 0.05%, lithium (Li+) below detection limit,, nickel (Ni++) 0.03%, lead (Pb++) 0.04%, cadmium (Cd++) 0.08%, zinc (Zn++) 0.08%, copper (Cu++) 0.05%, manganese (Mn++) 0.18%, iron (Fe++) 0.22%, and Cobalt (Co++)0.08%, Calcium (Ca++) 0.50%, Magnesium (Mg++)0.02%, Silicon (Si+4) 0.24%, Phosphorus (P-3) 0.08% and Sulphur (S--)0.01%. were determined.
