Abstract
Traditionally bryophytes are known to possess some bioactive components and, therefore, used throughout
the world as drugs and remedies to cure various diseases. In the present study, bioassay for antibacterial
activities was carried out using whole plant of Funaria hygrometrica Hedw. Different solvent fractions and
aqueous extracts of this moss were obtained and dried in vacuum. Antibacterial effect of these fractions
was determined by disc diffusion technique on different human pathogenic gram positive bacteria ie
Bacillus subtilis and Staphylococcus aureus, gram negative bacteria i.e. Escherichia coli and Pseudomonas
aeruginosa. The result was then compared with the standard antibiotic streptomycin. Both the aqueous and
organic crude extracts showed considerable activity against all the bacteria but maximum antibacterial
activity was observed in ethanol extract against Staphylococcus aureus. The phytochemical analysis of the
extract indicated the presence of steroid, flavonoids, alkaloids starch and oil.
