Phytochemical Investigation of Stachys hissarica: Antioxidant Activity, Flavonoid Characterization, and In Silico Analysis

open access: yesChemistry &Biodiversity, Volume 23, Issue 10, October 2026.
Stachys hissarica demonstrates remarkable antioxidant potential, driven by a rich profile of 35 annotated polyphenolic metabolites within its aqueous methanolic extract. Hydrophilic phenolics exhibit superior radical‐scavenging activity comparable to ascorbic acid. Integrated computational simulations reveal favorable oral bioavailability, low toxicity,

Using Olive Leaves to Enrich Olive Oil With Oleuropein Aglycone

open access: yesFood Science &Nutrition, Volume 14, Issue 10, October 2026.
Oleuropein was extracted from olive leaf by‐products and enzymatically converted to the bioactive oleuropein aglycone. Although hydrolysis was successful, oil enrichment was limited (6.5 mg/kg), likely due to micelle formation and complex aqueous–oil interfacial interactions, highlighting the need for further optimisation of oil enrichment strategies ...

Dual Antiviral and Immunomodulatory Effects of Phytochemicals in Influenza A Virus Infection: Targeting Key Host Signaling Pathways

open access: yesMicrobiologyOpen, Volume 15, Issue 5, October 2026.
Influenza A virus modulates host innate immune pathways, including TLR, RIG‐I, MAPK, and NF‐κB signaling, to support replication and drive inflammatory pathology. Plant‐derived phytocompounds target these interconnected pathways, offering a potential host‐directed immunomodulatory approach complementary to conventional antivirals.

Clerodendrum japonicum Extract Suppresses the Pathogenicity of Rheumatoid Arthritis Fibroblast‐Like Synoviocytes by Inhibiting METTL3‐Mediated ICAM2 mRNA Methylation

open access: yesCell Biochemistry and Function, Volume 44, Issue 9, September 2026.
ABSTRACT Clerodendrum japonicum (Thunb.) Sweet (Clerodendrum japonicum) is a traditional medicinal plant with reported anti‐inflammatory use, but its anti‐rheumatoid arthritis (RA) activity and molecular basis remain insufficiently characterized. Activated fibroblast‐like synoviocytes (FLSs) contribute to persistent inflammation and joint destruction ...
