Introduction: Vigna radiata L. is common vegetable plant cultivated all of the world. It’s belonging to the family Leguminosae (Fabaceae). Methods: To investigate for antibacterial activity of Vigna radiata, fresh and dried extracts of plant parts were tested on five strains of bacteria using standard well agar diffusion method. Results: Dried extracts showed more effective action on tested bacteria than of fresh extracts. Extracts prepared from dried stem and root exhibited better antibacterial activities than those prepared from fresh plant. Furthermore, there was no difference in the activity of ethanolic and aqueous extracts on isolated bacteria. Both of gram positive and negative bacteria showed approximately the same ratio of susceptibility to each part of plant.Conclusions: V. radiata has a potential antibacterial activity on clinically isolated bacteria. Dried extracts showed more effective action on tested bacteria than fresh extracts.

Key words: aqueous extract, ethanolic extract, Vigna radiata, bacteria.
