Turnips are among the most commonly grown and widely adapted root crops. Turnip roots are used raw or cooked as a vegetable and tops are used as potherb like spinach. Turnip roots are also grown for feeding livestock during fall and winter. In folk medicine, the powdered seed is said to be a remedy for cancer and breast tumors, while a salve derived from the roots can help to treat skin cancer. In this research, the antimicrobial activity of methanol, ethanol, n-hexane and chloroform extracts of turnip was evaluated with bacteria and mold. Alcoholic extracts of turnip were prepared and their antimicrobial activity was tested using an agar diffusion method. The highest antimicrobial activity was obsereved by methanolic extracts on Micrococcus spp while mold was resistant to this extract. Other alcoholic extracts also showed higher activity on Micrococcus spp.
