ABSTRACT
Medicinal plants are the best source to obtain a variety of herbal drugs. The use of plant extracts and photochemical both with known anti-microbial properties can be of great importance in therapeutic treatments. The plants have provided a good source of anti-infective agents and many of them remain highly effective in the fight against microbial infections. Therefore in the present study seven medicinal plants that are Emblica officinalis, Ficus bengalensis, Myristica fragrans, Acacia arabica, Aloe barbadensis, Ricinus communis and Zizyphus jujuba were screened for potential anti-bacterial activity against medically important bacterial strains, such as Pseudomonas aurogenosa, Proteus vulgaris, Staphylococcus aureus and Streptococcus cereviceae. The anti-microbial activity was determined in methanolic extracts using agar well diffusion method. Streptococcus cereviceae showed resistance against the plant extracts. Emblica officinalis and Aloe barbadensis showed strong anti-bacterial activity against all the tested bacterial strains. Hence, this plant extract can be used to evaluate any bioactive natural products that may serve as leads in the development of new pharmaceuticals that can address the unmet therapeutic needs.
