Natural compounds screened in plants with potency have protective activities contrary to knowledge and memory deficiency and other alternative. Accordingly, in response to improve and utilize this traditional medicine as a clinical remedy for instance cultivating cognition deficits, the pharmacology and manner of action of its active components must be supplementary considered. Thus, the medicinal plants of the most important strategic resources in the pharmaceutical industry are mainly important in the production. Known medicinal plant is plant that contains one or more of the numerous associates on chemical substances, one or more and low or high in concentration, and it has biological ability to inhibit or at any rate reduce the symptoms of the disease. Some medicinal plants such as Dracaena cinnabari, Verbena officinal, Polygala tenuifolia and Linux usitatissimum were studied to obtain more usefulness and lead to preferable treatment. Overall, the extracts of plants revealed significant activity on the bacterial species. Plants extracts selectively inhibited the growth of both gram positive and gram negative bacteria with zones of inhibition ranging from 7 mm to 14 mm at concentrations of 50 mg/mL. It can be concluded that the activity showed by the ethanolic extract of the plants is a result of the phytochemicals present in plants and these plants seems to be good applicants for further phytochemicals studies in an attempt to find new chemical entities combating resistant bacteria.
