Abstract:

The emergence of new infectious diseases, resurgence of several infections that appeared to have been controlled and the increase in bacterial resistance has led to the need for studies directed towards the development of new antimicrobials. Considering the challenge of obtaining new molecules with antimicrobial properties from microorganisms, identifying antimicrobials from other natural sources is of great importance. The phytochemical and antimicrobial activity of ethanolic leaf extracts of <em>Calotropis procera</em>, <em>Momordica charantia</em> and <em>Allium ascalonicum</em> was investi

Abstract:

In Nepal, traditional medicinal plants and herbs have long been relied upon for treating various diseases. This study was aimed to explore the antimicrobial properties of commonly used traditional medicinal plants. This study was conducted from December 2022 to June 2023 at the Department of Microbiology, St. Xavier's College, Maitighar, Kathmandu. In this study, antimicrobial property of 12 plants were tested against four ATCC cultures of bacteria- Staphylococcus aureus (ATCC 6538P), Staphylococcus epidermidis (ATCC 12228), Escherichia coli (ATCC 8739) and Pseudomonas aeruginosa (ATCC 9027).
