ABSTRACT

Physcia grisea were ground, extracted with ethanol, and some bioactive components determined before the extract was screened for phytochemical and antimicrobial activities on Salmonella typhi using Agar Cup Diffusion Technique. Chloramphenicol was used as a standard antibacterial agent for comparison. The phytochemical compounds found in the extract include tannins, flavonoids and alkaloids. The result of antimicrobial screening showed that P. grisea has antibacterial activity against S. typhi like chloramphenicol. However, P. grisea has a lower antimicrobial action than chloramphenicol.

Keywords: Physcia grisea, phytochemical, antimicrobial activities and Salmonella typhi
