Antioxidant Activities of Pentacyclic Triterpenes From Melipona beecheii Propolis and Their Semisynthetic Derivatives

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
M. beecheii propolis contains eleven identified PTs, including germanicone and glutinol, reported for the first time in this material. Antioxidant assays reveal Fe(III)‐reducing activity at an effective concentrations lower than DPPH radical‐scavenging activity.

Contrasting Coastal Environments Are Associated With Ecotype‐Specific Leaf Polyphenolic Profiles and Bioactivity in Corema album subsp. album

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
Leaves of two Corema album subsp. album ecotypes from two contrasting coastal microclimates were analysed using mineral profiling, (poly)phenolic assays, and LC–MS metabolomics. Ecotype‐specific metabolic strategies were revealed, linking environmental stress to antioxidant and cytotoxic activities.

The Chemical Constituents From Borojo and Their Anti‐Inflammatory Activity

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
Three new cyclopentenes and one new fused‑ring compound were isolated from borojo. BLH‑1, BLH‑5, and BLH‑9 inhibited TNF‑α and IL‐6 release, while BLH‑1, BLH‑2, BLH‑4, BLH‑6, and BLH‑7 reduced neutrophil migration in zebrafish models. BLH‑1 was found to suppress NF‑κB and STAT3 pathways, suggesting borojo is a promising source of anti‑inflammatory ...

Veratric Acid and the Cytotoxic Activity of Handroanthus impetiginosus Inner Bark Extract: No Association

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
Physicochemical characterization, phytochemical profiling, and in vitro cytotoxicity assessment of Handroanthus impetiginosus inner bark extract show that veratric acid, despite being readily identified by HPLC‐DAD, does not account for the observed cytotoxicity.
