Medicinal plants have been used as a natural source of medicine from one generation to another where they have their own personal benefits to human in treating diseases. Nowadays, there are a lot of therapeutic problems regarding the bacterial resistance to synthethic antibiotic happen among our community. The increasing report on the side effects of these synthetic antibiotics has led to the
screening of medicinal plants for antimicrobial activity, which Oroxylum indicum is not an exception. Oroxylum indicum belongs to the Family Bignoniaceae, is an important herbal folk medicine that have been used in many Asian countries to cure disease. Each part of this plant reported in previous phytochemicals studies to
have various bioactive compounds and secondary metabolites that function in biochemical defense. This study have been done to evaluate the antibacterial
activity, and to compare the effectiveness of methanolic leaf extract of Oroxylum indicum against selected bacterial strains that is most common in bacterial resistance. On the basis of result from disc diffusion, the antimicrobial assay of Minimum Inhibitory Concentration (MIC) have been done that is visual inspection to determine the lowest concentration of extracts that can inhibit bacterial growth.

This provided evidence that leaves of Oroxylum indicum plant could be the source of potent antibacterial medicine, especially in the treatment of highly resistant bacteria by increasing the concentration of leaves extract.
