Free radicals are freely available in human body (ROS, RON). But excess amount of free radicals cause damage to human body resulting many diseases such as diabetes mellitus, stroke and Alzheimer's disease. Antioxidants scavenge free radicals. Phenolic compounds and flavonoids are effective natural free radical scavengers. TPC assay and TFC assay confirm the presence of phenolic derivatives and flavonoids in a sample. In TPC assay, results are expressed as milligrams of pyrogallol equivalent (P...
