Ozone stress as a driving force of sesquiterpene emissions: a suggested parameterisation [PDF]

, 2012
Sesquiterpenes (C15H24) are semi-volatile organic compounds emitted by vegetation and are of interest in atmospheric research because they influence the oxidative capacity of the atmosphere and contribute to the formation of secondary organic aerosols ...

DPPH‐based Antioxidant Screening and Cellulase‐assisted Hydrodistillation of Matourea azurea: Improved Essential Oil Yield and Density Functional Theory Insights Into a Rare Terpene

Chemistry &Biodiversity, EarlyView.
ABSTRACT Essential oils are rich in bioactive molecules like terpenes and phenolic compounds, but have low yields, making process efficiency crucial. Enzyme‐assisted hydrodistillation is a sustainable alternative, enhancing oil release by degrading the cell wall.

Efficacy of Essential Oil of Algrizea minor Sobral, Faria & Proença (Myrtaceae) in Combating Methicillin‐resistant Staphylococcus aureus: Antibacterial and Virulence Modulation Studies Conducted In Vitro and In Vivo

Chemistry &Biodiversity, EarlyView.
This study explored the antibacterial, antivirulence, and in vivo effects of Algrizea minor essential oil (EOAM), against MRSA isolates. Chemical analysis by GC‐MS has been performed. The oil exhibited synergistic effects when combined with amoxicillin and oxacillin, inhibiting biofilm formation and reducing S. aureus‐induced hemolysis.

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 ...

Plant sesquiterpene lactones

Philosophical Transactions of the Royal Society B: Biological Sciences
Sesquiterpene lactones (STLs) are a prominent group of plant secondary metabolites predominantly found in the Asteraceae family and have multiple ecological roles and medicinal applications. This review describes the evolutionary and ecological significance of STLs, highlighting their roles in plant defence mechanisms against herbivory and as ...

Chemodiversity of Essential Oils From Eugenia uniflora L. Collected in Different Phytophysiognomies of the Coastal Region of Rio de Janeiro

Chemistry &Biodiversity, EarlyView.
Essential oils from Eugenia uniflora collected in different coastal phytophysiognomies of Rio de Janeiro showed notable chemodiversity. GC‐MS and GC‐FID analyses revealed nine chemotypes, mainly rich in curzerene and selina‐1,3,7(11)‐trien‐8‐one. ABSTRACT This study aimed to evaluate the yield, color, and chemical composition of Eugenia uniflora ...
