Seasonal Effect on the Chemical Composition of Lippia alba Volatile Chemotypes

open access: yesChemistry &Biodiversity, Volume 23, Issue 9, September 2026.
L. alba, a Brazilian medicinal species, is known for its volatile chemotypes, with fewer studies of its nonvolatile composition. Chemical characterization via GC‐MS and LC‐MS of five individuals, during the rainy and dry season, confirm the variability of the volatile composition but the nonvolatile composition was similar, with a discrete seasonal ...

Iridoid and phenylethanoid glycosides from Euphrasia pectinata

open access: yes, 2002
Two specimens of Euphrasia pectinata collected from different regions of northern Anatolia were studied to determine their iridoid and phenylethanoid glycosides. Four iridoid glucosides, aucubin (1), euphroside (2), ixorodoside (3), and boschnaloside (4),

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

Phytochemical Analysis Using LC–MS/MS and Anticancer Activity of Asphodelus tenuifolius Roots: Cell Cycle Arrest, Apoptosis, and In Silico Insights

open access: yesChemistry &Biodiversity, Volume 23, Issue 9, September 2026.
LC–HRMS/MS profiling of the hydroethanolic root extract of A. tenuifolius identifies 58 metabolites, including luteolin, emodin, luteolin‐7‐O‐β‐D‐glucoside, subaphyllin, and N‐trans‐feruloyltyramine. Integrated biological and computational analyses reveal apoptosis induction, G0/G1 cell‐cycle arrest, and multi‐target interactions, highlighting the ...

Polyphenolic and Biogenic Volatile Organic Compound Profiles of Endemic Metallophytes From the Thallium‐Rich Allchar Mining Area

open access: yesChemistry &Biodiversity, Volume 23, Issue 9, September 2026.
Six plant taxa endemic to the thallium‐rich Allchar Mining Area (North Macedonia) were profiled by HPLC/DAD/MSn and headspace GC–MS. Seventy‐eight polyphenols and 123 biogenic volatile organic compounds were identified, and multivariate analysis showed congruent, species‐specific polyphenolic and volatile signatures with no significant association with
