Some medicinal plants have been used as phytomedicines for thousands of years. Swertia chirata C. B. Clarke (Gentianaceae), distributed in Nepal, and Andrographis paniculata (Burm.f.) Wall. ex Nees (Acanthaceae), distributed in Gujarat, possess significant medicinal potential. These plants are considered important sources for the development of new drugs, and strategies such as combination chemotherapy, targeted therapy, and improved treatment adherence may help address challenges in cancer treatment. In this study, methanol, ethanol, and petroleum ether extracts of the aerial parts, including shoots and leaves, of both plants were evaluated for antimicrobial activity against various pathogenic bacterial strains. The results showed that the extracts exhibited varying degrees of antimicrobial effects. Ethanolic extracts showed superior antibacterial activity, warranting further studies to isolate, characterize, and elucidate the mechanisms of the active phytoconstituents.
