Nerium indicum  [Family:Apocynaceae] is commonly known as Arali [Tam] found throughout India, and has been used in the treatment of cancer, cardiotonic, leprosy and skin diseases. Plant parts such as root, bark and leaves are used. The present study is therefore undertaken to analyse its phyto chemical constituents in solvents like Benene, Chloroform and Alcohol and to screen its antibacterial activity. The dried leaf sample is extracted with solvents by cold maceration. The phytochemical analysis showed the presence of Alkaloids, Terpenoids, Cardiac glycosides, Saponins, Tannins & Carbohydrates in all the solvents. All the extracts were screened for antibacterial activity by Disc Diffusion Method. Out of the cultures used Staphylococccus aureus, Pseudomonas aeruginosa and Salmonella typhimurium  showed better zone of inhibition which is 10mm, 9mm & 7 mm respectively.
