Many plants possess antioxidant components that provide efficacy in lowering incidence and in lowering mortality rates of degenerative diseases in human. In this article, five selected herbs were evaluated for their total phenols using Folin-Ciocalteu (FC) reagent and gallic acid monohydrate as the standard. 1, 1-diphenyl-2-picrylhydrazyl (DPPH) assay was used to evaluate free radical scavenging capacity. Results showed that the phenolic content of each herbal plant extracts varied from 31.95 mg/g to 91.02 mg/g and their free radical scavenging capacity ranged from 32.82% to 93.48%. Correlation (p<0.05) between the phenolic content and the free scavenging capacity of the five selected herbal plants was observed.
