Pharmacologically tecoma stans flower is traditionally used for many ailments including cancer, diabetes and arthritis. It also possess anti-spasmodic, anti-nociceptive and antioxidant property. In present studies, Phytochemical investigations were done on powdered flower extracts based on the chemical constituents present. Anti-microbial activity was also performed on leaf and flower extracts of tecoma stans against different bacteria by using disc diffusion method. The zones of inhibition of the extracts were determined. The various extracts (Methanol,1μg/ml and Water) of flower were found to be effective anti-micribial activity against various gram positive and gram negative bacteria (Escherichia coli, Staphylococcus aureus and Bacillus subtilis using a standard as Amoxicillin (1μg/ml) compared to leaf extracts.
