In vitro antioxidant activity of extract of bulb of Allium sativum linn. Using DPPH and Frap assays with evaluation of total phenolic content

Manorma Kumari*, Navi Ranjan


The methanolic extracts of Allium sativum were investigated for its antioxidant activity by using 1,1-diphenyl-2- picryl hydrazyl (DPPH) radical scavenging assay and by ferric reducing antioxidant power (FRAP) assay. The total phenolic content was evaluated by Folin-Ciocalteu procedure. This study indicated that Allium sativum L. exhibited the high antioxidant activity and phenolic contents and can be used potentially as a readily accessible source of natural antioxidant. Due to its natural origin and potent free-radical scavenging ability, Allium sativum L. could be used as a potential preventive intervention for free radical-mediated diseases.
