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

Chemistry &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,

A New Lignan Glycoside and Phenylethanoid Glycosides from Strobilanthes cusia Bremek.

ChemInform, 2004
The root of Strobilanthes cusia BREMEK. (Acanthaceae), popularly known as Da-Ching-Yeh, has been commonly used in traditional Chinese medicine. It is used to treat influenza, epidemic cerebrospinal meningitis, encephalitis B, viral pneumonia, mumps, and severe acute respiratory syndrome (SARS). In this study, we found a new lignan glycoside (6) and two

Using Olive Leaves to Enrich Olive Oil With Oleuropein Aglycone

Food 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

MicrobiologyOpen, 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.
