Synergistic Enhancement of Antioxidant Activity in Arbutus unedo Leaf Extract by Biological Fluids: Implications for Functional and Nutraceutical Applications

Biotechnology and Applied Biochemistry, Volume 73, Issue 5, Page 2189-2201, October 2026.
ABSTRACT This study examined the effect of biological fluids (saliva, blood plasma, and urine) on the antioxidant capacity of an aqueous extract derived from Arbutus unedo leaves. The extract displayed a concentration‐dependent reducing activity in the ferric reducing power assay (IC50 = 292 ± 7.54 µg/mL) and phosphomolybdenum assays (IC50 = 461.67 ± 4.

Epicatechin-Loaded Nanocapsules: Development, Physicochemical Characterization, and NLRP3 Inflammasome-Targeting Anti-Inflammatory Activity

Biology
Epicatechin is a flavonoid of the catechin subclass, found in fruits and medicinal plants such as açaí and green tea, widely studied for its anti-inflammatory properties. However, flavonoids often present chemical instability, low aqueous solubility, and

Photochemistry of (+)-catechin and (-)-epicatechin

, 2008
Despite the well known fact that photolysis of free phenolic catechins give rise to isomerisation at the C-2 position (e.g. (-)-cis epicatechin converts to the sterically less hindered (-)-trans isomer), researchers have failed to isolate any ring opened

Phytochemical Characterization and Biological Activity of Stachys pinardii Extracts

Chemistry &Biodiversity, Volume 23, Issue 10, October 2026.
Ultrasound‐assisted methanol and aqueous extracts of Stachys pinardii are comparatively evaluated for phytochemical composition and biological activities. Solvent polarity markedly influences phenolic profiles and bioactivity. Although the methanolic extract contains higher total phenolics, the aqueous extract exhibits superior antioxidant and enzyme ...
