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

Abstract

Introduction: Phytochemicals 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). Methods: The present investigation comprises, estimation of total polyphenol, flavonoid, tannin, in vitro antioxidant assays such as total antioxidant capacity, DPPH, ABTS, b-carotene and ferric reducing power. Results: P. majus exhibited 64.25 mg GAE g^-1 extract of polyphenol phenol content, and better scavenging activity of DPPH (IC₅₀ = 7.95 mg mL^-1), ABTS^.+ (IC₅₀ = 373.78 mg mL^-1), and b-carotene (IC₅₀ = 122.56 mg mL^-1). Conclusion: Our results clearly demonstrated that phenolic extract P. majus has antioxidant capacity. Therefore is a valuable source of natural antioxidants.
