The antibacterial activities of the extracts against bacteria were tested by using agar well diffusion assay and the MIC values were determined by broth dilution assay. The ethanol and hot water extracts showed least antibacterial activity as compared to methanolic and ethyl acetate extracts. The least concentration were obtained 0.33mg/ml in ethanolic extract of stems, 1.98 mg/ml in ethyl acetate extract of stems and 0.05 mg/ml in methanolic extract of stems against P. aeruginosa.
