Lippia umbellata Cav.: Chemical Composition, Insecticidal, and Antimicrobial Activities

Chemistry &Biodiversity, Volume 23, Issue 8, August 2026.
Hexane extracts of Lippia umbellata leaves and flowers contain lupenone, α‐amyrin, and hentriacontane. They exhibit insecticidal activity against Drosophila melanogaster and inhibit AChE in vitro and in silico. Furthermore, the extracts can inhibit the growth of medically important bacteria and yeasts, including multidrug‐resistant strains.
