potential antioxidant activity using the quantitative2,2-diphenyl-1-picrylhydrazyl (DPPH)-free radical scavenging method and theircytotoxic effects were evaluated in the MTT assay using human ...
Isolation and characterization of the compounds responsible for the antimutagenic activity of Combretum microphyllum (Combretaceae) leaf extracts
Ames test using Salmonella typhimurium TA98, TA100 and TA102. The antioxidant activity of the three compounds were determined by the quantitative 2,2-diphenyl-1-picrylhydrazyl (DPPH)-free radical ...
The correlation between antimutagenic activity and total phenolic content of extracts of 31 plant species with high antioxidant activity.
antioxidant compounds present in methanol leaf extracts of 120 plant species was determined using a combination of Thin Layer Chromatography (TLC) and spraying with 2, 2-diphenyl-1-picrylhydrazyl (DPPH). The 31 ...
