Antioxidant and antibacterial response of hydroalcoholic extract of Plumeria alba leaves

Plants are the natural treasure of antioxidants and antimicrobial agents. Present study was intended to evaluate antioxidant potential Plumeria alba leaves hydroalcoholic extract (PALHE). Study involved phytochemical screening, antioxidant, antibacterial activity PALHE. The PALHE prepared using 95% ethanol as solvent through maceration method. determination total phenolic content (TPC) flavonoid (TFC). DPPH (1,1-Diphenyl2-picryl hydrazyl) radical scavenging assay used for investigated its against S. aureus E. coli well diffusion Various screening tests were carried out results revealed presence carbohydrates, reducing sugar, mucilage, proteins, steroids, volatile oil, tannins, flavonoids in Besides, moderate also result over ethanolic PALHE, where IC50 found be 23.96 mcg/ml. Additionally, TPC TFC 71.04 mg (GAE/g phenol terms gallic acid equivalent) 75.60 (RE/g rutin respectively.
