Constituents From the Flowers of Viburnum macrocephalum f. macrocephalum and Their α‐Amylase and α‐Glucosidase Inhibitory Activities

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
Two new cadinane‑type sesquiterpenes, viburetones A and B, were isolated from Viburnum macrocephalum flowers, marking the first cadinane skeletons in this genus. Viburetone A showed dual α‑amylase and α‑glucosidase inhibition comparable to acarbose, and docking clarified its binding.

Unprecedented 4/7 Bicyclic Carbon Skeleton Sesquiterpenoids With Anti‐Inflammatory Activities Isolated From the Root of Lindera glauca

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
Glasesquiterpenoid A (1) with an unprecedented 4/7 bicyclic carbon skeleton was the first example reported in the class of sesquiterpenoids. ABSTRACT Six new sesquiterpenoids glasesquiterpenoids A−F (1−6), together with two known ones, 7 and 8, were coisolated from the root of Lindera glauca.

Composition and Chemical Variability of Trunk Bark Oil of Pachylobus klaineanus (Pierre) Guillaumin. From Côte D'Ivoire

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
Composition of trunk bark oil of Pachylobus klaineanus. ABSTRACT The chemical composition of 50 individual trunk bark oil samples from plants of Pachylobus klaineanus (Pierre) Guillaumin. collected in eight Ivoirian localities was investigated by GC‐FID (50 samples), GC/MS (30 samples), and 13C‐NMR (23 samples).

Chemophenetic Analysis of Ten Wild‐Growing East Adriatic Helichrysum italicum (Roth) G. Don (Gnaphalieae, Asteraceae) Populations

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
Essential oils of immortelle are well known for their diversity in composition, but most studies on phytochemistry focus on bioactivity, while variability has rarely been directly studied. We investigated variability in the composition of essential oils and extracts from different populations along the east Adriatic coast, as well as environmental ...

Phenolic Profiling and Bioactivity Evaluation of Stachys aleurites Extracts: LC–ESI–MS/MS Characterization, Antioxidant Capacity, and Enzyme Inhibitory Potential

Chemistry &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
