Background: Stemodia viscosa is one of the common aromatic weed presents in the agricultural field. This current study is intended to identify the phytochemicals present in S. viscosa; to quantify the phenol, flavonoids and tannins content; and to screen the antibacterial activity.
Results: The quantitative analysis of present study exposed that both stem and leaves of S. viscosa contain more tannin content than total phenolics and flavonoids. FTIR spectra showed the presence of the functional group in both stem and leaf extracts which have medicinal properties and can be used as antimicrobial, antiinflammatory and antidiabetic agents.
Methods & Findings: The antibacterial activity of S. viscosa was tested by disc diffusion method. The dried stem and leaf samples were mixed in different solvents namely acetone, methanol and water. All extracts were showed antibacterial activity against the human pathogenic bacterial strains namely Bacillus subtilis, Escherichia coli, Klebsiella pneumoniae, Salmonella typhi and Serratia marcescens.
Keywords: Aromatic weeds, Stemodia viscosa, phytochemical analysis, FTIR analysis, antibacterial activity.
