A Comparative Phytochemical Analysis of Olive Oils Derived From Two Underexplored Tunisian Cultivars: Chemchali and Fougi

Chemistry &Biodiversity, EarlyView.
ABSTRACT This study represents the first comprehensive investigation into the valorization of two rare olive cultivars, Chemchali and Fougi, cultivated in southern Tunisia. The main objectives were to assess the quality of their virgin olive oils (VOOs) by analyzing their chemical composition, sensory profile, quality indices, and physicochemical ...

Flavonoid Profile, Biological Potentials, and In Silico Approaches of Methanol Extracts on AChE: Amaranthus retroflexus L.

Chemistry &Biodiversity, EarlyView.
ABSTRACT This study investigated the flavonoid compounds and their biological activities in methanol extracts obtained from root, stem, leaf, and flower parts of Amaranthus retroflexus L. Flavonoids in the extracts were characterized for the first time by liquid chromatography–highresolution mass spectrometry (LC–HRMS), and a total of eight flavonoid ...

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 ...

Larvicidal Activity of Phytochemicals From Handroanthus impetiginosus Seeds Against Culex quinquefasciatus

Chemistry &Biodiversity, EarlyView.
The hexane extract was obtained from the seeds of H. impetiginosus, from which fatty acids and FAMEs were obtained. The three samples were tested on C. quinquefasciatus larvae, promoting mortality with moderate LC50 values. The hexane extract was analyzed by gas chromatographymass spectrometry (GC‐MS), and the most abundant compounds were ethyl oleate (

Characterization and Variability Analysis of Volatile Metabolites From Acer saccharum Leaves From Québec Region

Chemistry &Biodiversity, EarlyView.
ABSTRACT Volatile secondary metabolites in plants can serve as valuable biomarkers for the plant's health, stress response, and pest or disease detection. We have investigated the volatilome of Acer saccharum (sugar maple) leaves using two complementary extraction techniques: headspace‐solid phase micro‐extraction coupled with gas chromatography‐mass ...
