Abstract

Medicinal plants are the wealthy source of antibacterial agents and curatives. Tecoma stans are commonly practiced medicinal plants in the villages of Salem District, Tamilnadu (India). Plants grown in this region are not systematically tested for their biological activities in general and antimicrobial activity in particular. Hence, In vitro antibacterial activity of leaf, seeds, Flowers extracts of plant was tested by agar plate method against three bacterial organisms E.Coli,Entero bacter, bacillus creuseus. Gram-negative bacterial strains were more susceptible to the crude extracts as compare to gram-positive. However, this study revealed maximum growth inhibition and effectiveness was remarkably observed in the extracts of Tecoma stans. These results indicate that leaves, seeds, flowers have a potential broad spectrum antibacterial activity.

Keywords: Tecoma stans, Antibacterial activity, Agar plate method.
