Background: Medicinal plants have been commonly used in traditional medicine against different ailment from ancient time. The present study was an attempt to determine the anti-bacterial traits of commonly available medicinal plants, especially having topical uses. Methods: A total of four types of locally available medicinal plant samples inclusive of Turmeric ( Curcuma longa , rhizome), Marigold ( Tagetes minuta , leaves), Durva Grass ( Cynodon dactylon , whole plant), and Hibiscus ( Hibiscus rosa-sinensis , leaves) were collected. Crude, hot water, and solvent (ethanolic and methanolic extracts of the samples) were tested for their antimicrobial traits by agar well-diffusion method on Mueller-Hinton agar. The minimal inhibitory concentration (MIC) of each sample was determined by the microdilution technique. Microbiological quality of the samples was also checked. Results: Microbial contaminations were found in all the samples. Beside viable bacteria and fungi, all samples contained Staphylococcus spp. and Pseudomonas spp. The proliferation of Klebsiella spp. was observed in the majority of the samples. Notable antimicrobial activities were exhibited by the medicinal plant parts tested in this study. Ethanolic and methanolic extracts showed remarkable efficiency in eliminating the growth of tested bacterial isolates although crude and hot water extracts projected no considerable inhibitory effects. The majority of the samples had a MIC value at 12 mg/mL. Conclusion: The findings of the present study reveal that the medicinal plant samples had remarkable antimicrobial traits which portray their potential for the commercial application against different infectious diseases.
