Abstract
Antimicrobial resistance was an important issue that needed to be
addressed due to the indiscriminate use of antibiotics in humans and animals.
This investigation seeks to explore the antimicrobial and larvicidal properties
of Elytraria acaulis herb extracts. The methanol extract exhibited
significant antibacterial activity, with the highest zone of inhibition
recorded at 20.0±0.3 mm against Escherichia coli and 12.0±0.5 mm against
Klebsiella pneumoniae. In antifungal assays, the methanol extract showed
strong effects against C.albicans (16±0.4 mm) and other species, while
acetone and chloroform extracts displayed moderate activity. The larvicidal
effectiveness of the methanol extract was notable, achieving the highest
mortality rates at 150 ppm after 48 hours across mosquito larvae. LC50 values
ranged from 9-125 ppm for Culex quinquefasciatus and 33-120 ppm for Aedes
aegypti. These findings align with previous research highlighting the
antibacterial and antifungal potential of plant extracts, emphasizing the role
of phytochemicals such as phenolics and flavonoids. Overall, Elytraria
acaulis demonstrates promise as a natural source for developing
antimicrobial and larvicidal agents.
