Effect of Fruit Maturation Stage on the Chemical Composition and Antioxidant and Cytotoxic Activities of Piper nigrum Essential Oil

open access: yesFlavour and Fragrance Journal, EarlyView.
The essential oils of Piper nigrum show marked chemical and biological variation across fruit maturation stages. Ripe fruits yield oils with the strongest antioxidant and cytotoxic activities, demonstrating that maturation directly modulates volatile composition and enhances the bioactive potential of this aromatic species.

Deciphering the biosynthetic pathways of lichen acids

open access: yesNew Phytologist, EarlyView.
Summary Depsides and depsidones are polyketide‐derived lichen acids widely distributed in lichen thalli, yet the biosynthetic gene clusters (BGCs) responsible for their production remain poorly understood. To address this gap, we investigated the diversity and evolutionary relationships of polyketide BGCs in lichens.

Flavonoids as Anxiolytics in Animal Tests: Systematic Review, Meta‐Analysis, and Bibliometrical Analysis

open access: yesPhytotherapy Research, Volume 40, Issue 1, Page 77-99, January 2026.
ABSTRACT Flavonoids are natural secondary metabolites of plants with a basic composition derived from polyphenols that can produce a plethora of different neurophysiological effects, some of which are relevant to anxiety disorders. As such, many flavonoids have been evaluated in behavioral screens in preclinical research on anxiolytics.
