Antibacterial Activity and Phytochemical Screening of Salvinia auriculata Aubl. from Tirumala Hills, Tirupati

The present paper deals with the antibacterial studies and Phytochemical screening of Salvinia auriculata Aubl. The different parts of Salvinia auriculata Aubl. was collected, gabbled, pulverized, air dried and subjected to gradient extraction with soxhlet apparatus with different solvents (acetone, ethanol, methanol, ethyl acetate and benzene) was screened phytochemically for its chemical components and antibacterial assays. Phytochemical studies showed the presence of Alkaloids, Flavonoids, Phenols, Tannins, and Saponins in higher to moderate concentrations and percentage of Alkaloid 0.25, Flavonoid 0.48, Saponin 0.36, Tannin 0.28 and Phenol 0.36. Antibacterial assay of the different extracts by the use of agar Disc-Diffusion method revealed that methanol and acetone extracts showed maximum activity against P.aeuroginosa, E.coli, and S.aureus.
