Phytochemical Screening, Anti-microbial Evaluation of Extract of Salvia officinalis L.

Abstract

The present study was conducted to asses phytochemical and anti microbial activity of extracts of Salvia officinalis L. against bacteria and fungi. This experiment was conducted to valorize Salvia officinalis post-distilled aerial parts as natural antioxidants. Total phenolic contents were determined, the phenolic constituents were determined using HPLC with UV detection S. officinalis residues revealed phenolic diterpenes as main components. The phytochemical test revealed that the presence of proteins, carbohydrates, lipids, alkaloids, phenols, flavonoids, steroids, glycosides, tannins, terpenoids and resins. The antibacterial activity of methanol extract shows maximum inhibition zone on Gram positive bacteria. These results include antioxidant, antimicrobial properties. These findings suggest that S. officinalis by-products, particularly at flowering, may be considered as an interesting source of natural antioxidants, anti microbial properties.
