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 ¼ 7.95 mg mL�1), ABTS�þ (IC50 ¼ 373.78 mg mL�1), and b-carotene (IC50 ¼ 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.
Keywords: Prasium majus; Quantification of phenolic classes; Antioxidant activity
