2,2 diphenyl 1 picrylhydrazyl radical inhibition of Kaempferia galanga extract. The above reference chart addresses the relationship between percentage inhibition of DPPH with ethanolic concentrates of KGR. X pivot addresses the concentrations of ethanolic extract of KGR and standard from 100 μg for each ml to 500 μg for every ml. The Y pivot addresses percentage inhibition of DPPH radical by both the extract and standard. Blue colour denotes the KGR extract while the red colour denotes the standard drug Vitamin C. The figure addresses the mean with the SD of 3 observations. P value is <0.05 is considered. SD: Standard deviation, KGR: Kaempferia galanga rhizome, DPPH: 2,2-diphenyl-1-picrylhydrazyl
