First Insights Into the LC‐HRMS Profiling and Biological Activities of Crocus graveolens

open access: yesFood Science &Nutrition, Volume 13, Issue 8, August 2025.
This study reports the first comprehensive analysis of Crocus graveolens Boiss. & Reut. using LC‐HRMS, identifying 33 secondary metabolites, with rutin as the major compound (162.808 ± 4.5 μg/g extract). The extract showed moderate antioxidant activity and effectively inhibited acetylcholinesterase (30.88% ± 1.51%) and butyrylcholinesterase (61.22% ± 0.

Crocetin promotes angiogenesis in human endothelial cells through PI3K-Akt-eNOS signaling pathway [PDF]

open access: yes, 2019
Previous studies proved the pro-angiogenic effect of Crocetin, a natural carotenoid dicarboxylic acid, in both in vivo and in vitro models. However, the exact mechanism of Crocetin action has not completely been elucidated yet. The current experiment was

Elicitor Specific Mechanisms of Defence Priming in Oak Seedlings Against Powdery Mildew

open access: yesPlant, Cell &Environment, Volume 48, Issue 6, Page 4455-4474, June 2025.
ABSTRACT Defence priming sensitises plant defences to enable a faster and/or stronger response to subsequent stress. Various chemicals can trigger priming; however, the response remains unexplored in oak. Here, we characterise salicylic acid (SA)‐, jasmonic acid (JA)‐, and β‐aminobutyric acid (BABA)‐induced priming of oak seedlings against the causal ...

Partially substituting alfalfa hay with hemp forage promotes the health and well‐being of goats via altering ruminal and plasma metabolites and metabolic pathways

open access: yesAnimal Research and One Health, Volume 3, Issue 1, Page 82-101, February 2025.
Hemp forage (HF) seems to be a suitable forage for ruminants that exert health and growth promoting activities. The current study investigated the effects of substituting alfalfa hay with hemp forage (HF), which is high in nutritional value and rich in phytochemicals, on rumen and plasma metabolome using HPLC‐MS. The numbers of differential metabolites
