Phenolic Profiling and Bioactivity Evaluation of Stachys aleurites Extracts: LC–ESI–MS/MS Characterization, Antioxidant Capacity, and Enzyme Inhibitory Potential

open access: yesChemistry &Biodiversity, Volume 23, Issue 9, September 2026.
Solvent polarity shapes the phytochemical and bioactivity profile of Stachys aleurites. Methanol extraction enriches phenolics, especially verbascoside and chlorogenic acid, and enhances antioxidant and enzyme inhibitory activities, whereas the aqueous extract shows selective metal‐chelating and BChE inhibitory potential. ABSTRACT Natural products rich

Bioinspired Design and Synthesis of Polyphenolic Star‐Like and Hyperbranched Polyester Models

open access: yesChemistry – A European Journal, Volume 32, Issue 33, 1 September 2026.
Gallotannin‐inspired star‐like and hyperbranched aromatic polyesters were synthesized from D‐glucose and ABn‐type phenolic acid monomers, such as protocatechuic acid. This bioinspired approach afforded polyphenolic polymeric nanoparticles able to encapsulate hydrophobic dyes, opening new perspectives for biobased encapsulation and delivery systems ...

Spouted bed drying parameters and adjuvant effects on polyphenol retention and antioxidant activity in mango peel powders

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 9, Page 4579-4596, September 2026.
Spouted bed drying of mango peels with colloidal SiO2 and corn starch produces a free‐flowing powder with reduced agglomeration, increased drying yield, and preserved antioxidant and polyphenol content. Abstract The production of polyphenol‐rich powders is a promising strategy for valorizing agro‐industrial byproducts. This study evaluated drying yield,
