Insights into the effects of reproductive phase thermal stress on physiology and yield‐related traits of rice cultivars

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract High temperatures lead to a significant drop in rice (Oryza sativa L.) productivity worldwide, especially during the reproductive stage. This research was piloted to evaluate 10 promising rice cultivars for their ability to withstand high‐temperature stress (HS) during the reproductive phase and to assess the impact on physiology and yield ...

Five New Iridoids From the Leaves of Viburnum macrocephalum f. macrocephalum and Their Free Radical Scavenging Activity

open access: yesChemistry &Biodiversity, Volume 23, Issue 9, September 2026.
Five new iridoids, viburetins D–H, featuring dioxatricyclodecane and ring‑opened monocyclic skeletons, are isolated from the leaves of Viburnum macrocephalum f. macrocephalum, enriching the chemical diversity of Viburnum. Preliminary DPPH and ABTS assays reveal varying degrees of radical scavenging activity.

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

open access: yesChemistry &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.

Bioactive Phenolics of Lygeum spartum L.: Insights Into Antioxidant, Anticholinesterase, and Antityrosinase Activities

open access: yesChemistry &Biodiversity, Volume 23, Issue 9, September 2026.
Phenolic profile and bioactivity of Lygeum spartum L. ABSTRACT The phenolic composition of roots and leaves of Lygeum spartum L., a Mediterranean Poaceae species, was analyzed by HPLC–DAD, revealing an organ‐specific distribution of phenolic compounds, with ferulic acid identified as the predominant phenolic compound in the methanolic leaf extract (4 ...

Chemical Characterization and Pharmacological Activity of Byrsonima crassifolia (L.) Kunth (Murici): Antinociceptive Effects, Edema Reduction, and Molecular Docking

open access: yesChemistry &Biodiversity, Volume 23, Issue 9, September 2026.
Hydroethanolic extracts from Byrsonima crassifolia leaves and bark exhibit potent anti‐inflammatory and antinociceptive activities in zebrafish. Phenolic compounds, particularly kaempferol‐3‐O‐rutinoside, isoquercitrin, and rutin, target TRPA1, TRPV1, and COX‐2, integrating phytochemical, biological, and molecular docking evidence to support murici as ...
