Antioxidant activity profiling by spectrophotometric methods of phenolic extract of Prasium majus L

Abstract

IntroductionPhytochemicals are extensively found at different levels in many medicinal plants. To investigate the phenolic compound content and in vitro antioxidant activity of phenolic extract from Prasium majus L (Lamiaceae). MethodsThe present investigation comprises, estimation of total polyphenol, flavonoid, tannin, in vitro antioxidant assays such as total antioxidant capacity, DPPH, ABTS, β-carotene and ferric reducing power. ResultsP. majus exhibited 64.25 mg GAE g−1 extract of polyphenol phenol content, and better scavenging activity of DPPH (IC50 = 7.95 μg mL−1), ABTS+ (IC50 = 373.78 μg mL−1), and β-carotene (IC50 = 122.56 μg mL−1). ConclusionOur results clearly demonstrated that phenolic extract P. majus has antioxidant capacity. Therefore is a valuable source of natural antioxidants.
