Seasonal Effect on the Chemical Composition of Lippia alba Volatile Chemotypes

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
L. alba, a Brazilian medicinal species, is known for its volatile chemotypes, with fewer studies of its nonvolatile composition. Chemical characterization via GC‐MS and LC‐MS of five individuals, during the rainy and dry season, confirm the variability of the volatile composition but the nonvolatile composition was similar, with a discrete seasonal ...

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.

Evidence for the Induction of Anxiolytic‐Like Behavior and Memory Preservation by (+)‐Dihydrocarvone Through Studies in Adult Zebrafish and In Sílico

Chemistry &Biodiversity, Volume 23, Issue 8, August 2026.
(+)‐Dihydrocarvone exhibited anxiolytic‐like and memory‐preserving effects in adult zebrafish. Behavioral assays showed reduced anxiety and improved cognitive performance, while in silico docking revealed strong interactions with GABAergic and cholinergic targets. These findings suggest (+)‐dihydrocarvone as a promising neuroactive compound for anxiety

Resilience of floral scent emission after florivory

Plant Biology, Volume 28, Issue 5, Page 1491-1506, August 2026.
Florivory is thought to affect floral traits, impacting pollination. However, our data suggest a stability in post‐florivory scent emission, which may guarantee the maintenance of pollinator visitation regardless of florivory, indicating a resilience of natural systems with multiple and simultaneous interactions. Created in BioRender. Tunes, P.

Distribution of Iridoid Glucosides in Plants from the Genus (Verbenaceae): An investigation of (Mill.) N.E. Brown

Natural Product Communications, 2007
The distribution of iridoid glucosides in plants from the genus Lippia (Verbenaceae) is described. In the present work, three known iridoids (theviridoside, mussaenoside and gardoside) were isolated from the roots of L. alba and were confirmed by NMR ( 1

Essential Oils and Their Multifunctional Activities Against Pseudomonas aeruginosa: Current Evidence and Perspectives

MicrobiologyOpen, Volume 15, Issue 3, June 2026.
Essential oils show multifunctional activity against multidrug‐resistant Pseudomonas aeruginosa by targeting bacterial membranes, quorum sensing, biofilm formation, virulence traits, and antibiotic susceptibility. Their translational potential depends on standardized composition, optimized delivery systems, safety assessment, and clinical validation ...
