Abstract: Cassia fistula (Family - Leguminosae) is a deciduous and ornamental tree native to India and Sri Lanka. It is also known as golden shower, Indian laburnum, baton casse, keyok, klober etc. It is a fast growing tree of deciduous type and grows up to 9 m. The leaves of the tree are compound and have 4-8 pairs. Flowers of the tree are golden yellow in color and they hang in bunch which looks like a shower of up to 40 centi-meters. They are widely cultivated worldwide because of beauty. The flowers of the tree attract bees and butterflies.Cassia fistulaThere are various species of cassia worldwide which are used for medicinal purposes. Some species of the tree are used for their laxative properties. The study was carried out with an objective to investigate the antibacterial potentials of leaves of Cassia fistula. The aim of the study is to assess the antimicrobial activity and to determine the zone of inhibition of extracts on some bacterial strains. The antimicrobial activity was determined in the extracts using agar disc diffusion method. The antibacterial activities of extracts of Cassia fistula were tested against Gram-positive and Gram-negative pathogenic bacteria and different zone of inhibition was formed. The results showed that the remarkable inhibition of the bacterial growth was shown against the tested organisms. The microbial activity of the Cassia fistula was due to the presence of various secondary metabolites. Hence, these plants can be used to discover bioactive natural products that may serve as leads in the development of new pharmaceuticals research activities.
