Rheo discolor Hance. is extensively used in Indian traditional and folklore medicines to cure various human ailments. The preliminary phytochemical screening of the leaves revealed the presence of Alkaloids, Flavonoids, Saponins, Tannins & Phenolic compounds, Cardiac glycoside and Terpenoids. In vitro antibacterial studies on the leaf extracts were carried out on eight medically important bacterial strains, including Staphylococcus aureus, Bacillus subtilis, Staphylococcus citrus, Serratia sp., Salmonella typhi, Pseudomonas aeruginosa, Klebsiella pneumonia, and Proteus vulgaris which were procured from Department of Microbiology, RVS Hospital, Sulur, Coimbatore, Tamilnadu, using agar disc diffusion method. The results of our antibacterial assay revealed that the extract showed good inhibitory activity against all the tested pathogens compared with standard antibiotics like chloromphenicol.
