Abstract
Phytochemical screening, antibacterial activity and anti-inflammatory properties of Tephrosiavillosa root, stem and leaves were assessed in this study. Phytochemical screening of the plant extracts (root, stem and leaf) of Tephrosia villosa was made by running the root, stem and leaf through solvent such as ethanol. The ethanolic extract of root indicated positive tests for steroids, alkaloids, amino acids and proteins, saponins, flavones, anthocyanines and phenolic compounds. Ethanolic extract of stem and leaf indicated positive tests for steroids, alkaloids, carbohydrates, glycosides, amino acids and proteins, saponins, flavones, anthocyanines and phenolic compounds. Ethanolic extracts of root, stem and leaves tested for their antibacterial activity, the extracts in each series indicate modest to higher activity against both Gram negative and Gram positive pathogenic microorganisms’.

The leaves extract of Tephrosia villosa indicated promising activity against the dangerous pathogens such as K. pneumonia, Salmonella typhi and Salmonilla paratyphi, by producing 13mm, 13mm and 12mm zone of inhibition around the inoculation. Plant root extract was effective against the Staphylococcus aureus (12mm), Salmonella typhi (12mm) and Salmonilla paratyphi (11mm).
