Antioxidant activity profiling by spectrophotometric methods of phenolic extract of Prasium majus L
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 g1 extract of polyphenol phenol content, and better scavenging activity of DPPH (IC50 ¼ 7.95 mg mL 1), ABTSþ (IC50 ¼ 373.78 mg mL 1), and b-carotene (IC50 ¼ 122.56 mg mL1). Conclusion: Our results clearly demonstrated that phenolic extract P. majus has antioxidant capacity. Therefore is a valuable source of natural antioxidants.
Key words: Prasium majus,Quantification of phenolic classes, Antioxidant activity.
