The present communication attempts to study the antimicrobial activity of successive extraction using n-hexane, chloroform, ethyl acetate, alcohol and separate aqueous extract from whole plant of Ruellia tuberosa L. against different bacterial and fungal organisms (ATCC , MTCC) using disc diffusion method. The chloroform, ethyl acetate, alcohol and aqueous extracts were active against all the bacteria tested and showed significant antibacterial properties. The aqueous extract exhibited less activity against fungal organisms. Thus it may be informed that Ruellia tuberosa L. extract may be used to treat oral bacterial diseases.

Key words: Ruellia tuberosa, Antimicrobial activity, Successive extractions, MIC
