Exploring Chemical Variability in the Essential Oil of Artemisia absinthium L. in Relation to Different Phenological Stages and Geographical Location

Chemistry &Biodiversity, EarlyView.
ABSTRACT The plant essential oils (EOs) play a fundamental role in the adaptation to different habitats and environmental conditions. To verify the influence of these factors on the EO of Artemisia absinthium L., we conducted a pharmacognostic study on this species, collected during both the vegetative (V) and flowering (F) stages, in two different ...

New Terpenoids from Viguiera dentata: In Silico Pesticide‐Likeness Properties, Acetylcholinesterase Inhibition, Molecular Docking, and Evaluation against Spodoptera frugiperda

Chemistry &Biodiversity, EarlyView.
The chemical analysis of aerial parts of the melliferous Viguiera dentata led to the isolation of 20 substances, including the new cycloartanes 24‐epi‐argentatin C, 7β‐hydroxy‐24‐epi‐argentatin C, 7β‐hydroxy‐argentatin B. In‐combo results indicated that specific argentatins and ent‐kaurenoic acids have the potential to control Spodoptera frugiperda ...
