Antimicrobial Screening of the Solvent Extracts of Halophytic Plant Suaeda maritima (L.) Demort. Against Selected Pathogens

The antimicrobial activity of leaf and stem extracts of halophytic plant Suaeda maritima (L.) Demort. against, some plant and human pathogens. Plant parts of S. maritima were collected from the mangrove habitats of Pandi and Pora regions of Godavari estuary, near Amalapuram, Andhra Pradesh, India. Plant parts are dried and extracts were obtained successfully with hexane, chloroform, methanol and water, using Soxhlet extraction apparatus. The antimicrobial activity of the plant extracts on various test organisms including multiple antibiotic resistant bacteria were investigated by Well Diffusion Method under in vitro conditions. The plant extracts have shown promising antimicrobial activity against all tested organisms. Among the four extracts, water extract of S. maritima showed appreciable antimicrobial activity against all bacterial and fungal strains. It reveals that halophytic plant has antimicrobial compounds which can act against microorganisms and they can also be used in the treatment of infectious diseases caused by resistant pathogenic microorganisms.
