Secondary Metabolites Composition and Their Histochemical Localization in the Fruit of Piper malgassicum Papini, Palchetti, Gori and Rota Nodari (Piperaceae)

Chemistry &Biodiversity, EarlyView.
ABSTRACT The anatomy, histochemistry, and secondary metabolite composition were investigated on the drupes of Piper malgassicum, one of the components of the spice voatsiperifery pepper. The high amount of piperine recorded with high‐performance liquid chromatography with photodiode‐array detection analysis was localized with histochemistry mainly ...

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.

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 ...

Multifaceted Study of Medicago marina Essential Oil: Chemical Composition, Antidiabetic, and Phytotoxic Insights via In Vitro and In Silico Approaches

Chemistry &Biodiversity, EarlyView.
ABSTRACT The essential oil of Medicago marina was subjected to analysis at vegetative and reproductive stages of development, with a particular emphasis on its chemical composition, α‐amylase inhibition, and allelopathic activities. The results of the gas chromatography and molecular docking studies demonstrated alterations in oil yield and composition

PEK14: A Kinesin‐4 Necessary for Male‐Derived Fertility in Arabidopsis thaliana

Cytoskeleton, EarlyView.
ABSTRACT Of the 61 kinesins annotated in Arabidopsis thaliana, many are still without assigned function. Here, we have screened an insertional mutant library of Arabidopsis pollen‐expressed kinesins for fertility defects. Insertional mutants for three kinesins showed a significant reduction in seed set.
