Stevia rebaudiana belonging to the family Asteraceae is thought to inhibit the growth of certain bacteria. Antibacterial activities of crude extracts were examined by well diffusion method. Each plant extracts was dissolved in respective solvents such as Acetone and Chloroform, Ethanol, Hexane, and Petroleum ether. Among the five types of extract, the highest inhibition zone was observed in Ethanol extract and second most acetone extract followed by chloroform, petroleum ether and hexane. In our current studies S. rebaudiana was highly suppressed to Staphylococcus aureus, second most Klebsiella pneumonia followed by Escherichia coli and Pseudomonas aeruginosa. Our current results plant 2 (GKVK university Bangalore) sample were exhibited high antibacterial activity against wound infected pathogens second most plant 4 (Yercaud) followed by plant 1 (kolli hills) and plant 3 (Jaipur).
