摘要

In recent times, the strains of multidrug-resistant bacteria have been rising, causing a health crisis that has become a major global concern. Therefore, it is crucial to develop new drugs to address this hindrance. In this study, antimicrobial activities and GC–MS analysis of five wild edible plants (WEPs) viz. Colocasia lihengiae, Blumea lanceolaria, Rhynchotechum ellipticum, Mussaenda roxburghii, and Rhaphidophora hongkongensis used by tribal communities of the Karbi-Anglong Plateau (India) were studied. The methanolic leaf extracts (MeOHLEs) showed remarkable antimicrobial activity at different concentrations (25 µg/mL, 50 µg/mL, 75 µg/mL, 100 µg/mL), with inhibition zones ranging from 1.1 to 9.0 mm. The concentration of 100 µg/mL exhibited the strongest and 25 µg/mL the least effective against all test pathogens (E. coli, P. aeruginosa, and S. aureus) during the disc diffusion assay. GC–MS analysis of the MeOHLEs revealed the presence of fourteen bioactive compounds with known antimicrobial effects. This investigation underscores the antimicrobial potential of the WEPs as functional foods.
