IN- VITRO EVALUATION OF ANTIOXIDANT ACTIVITY OF CURCUMA CAESIA ROXB.Abstract
This study was undertaken to examine the antioxidant activity of methanolic extract of rhizomes of Curcuma caesia using DPPH free radical scavenging assay. The IC50 (The concentration of sample required to scavenge 50% of DPPH free radical) was calculated by plotting graph between % inhibition vs concentration. The Butylated Hydroxytoluene was used as standard antioxidant in comparison to methanolic extract of Curcuma caesia. The IC 50 value of extract and Butylated Hydroxytoluene was found to be 862.35 µgm and 46.25 µgm for 2 ml of 500 µM concentration of DPPH. This suggests that methanolic extract of Curcuma caesia had moderate IC 50 value as compared to Butylated Hydroxyltoluene.
