Pastinaca sativa L.: Nutritional Composition, Phytochemistry, and Pharmacological Properties Supporting Its Potential as a Functional Food and Therapeutic Agent

open access: yesFood Science &Nutrition, Volume 14, Issue 5, May 2026.
Food‐grade processing of Pastinaca sativa (parsnip) converts a nutrient‐rich plant matrix (dietary fiber, fructans, phenolics) through washing/slicing/enzymatic treatment and ingredient preparation into functional food ingredients, including fiber concentrates, antioxidant‐rich fractions, and parsnip powders/extracts.

Stereochemistry of base-catalyzed double-bond migration in allyl ethers

open access: yes, 1970
Base-catalyzed isomerization of trans-3-methoxy-1-phenylpropene yields stereospecifically as the initial product cis-1-methoxy-3-phenylpropene. This is caused by the (intermediate) formation of the cis-1-methoxy-trans-3-phenylallyl anion (I), which is ...

Fruit respiration: putting alternative pathways into perspective

open access: yesNew Phytologist, Volume 250, Issue 1, Page 54-73, April 2026.
Summary Over the past century, research has significantly advanced our understanding of fruit respiration, from (eco)physiological processes to molecular mechanisms. This review focuses on the functional relevance and regulatory roles of mitochondrial alternative respiratory pathways (ARPs) during fruit growth and ripening.

Chitosan‐Based pH‐Responsive Films and Edible Coatings to Enhance Fruit Shelf‐Life: Impact of Plant Biomolecules and Composition

open access: yesFood Chemistry International, Volume 2, Issue 1, Page 9-22, March 2026.
Chitosan based coatings/films forming solution with the use ofplant extracts and parameters for fruit shelf life analysis. ABSTRACT Fresh fruits are a natural source of various minerals and vitamins, which are essential for human health. However, a rapid rate of respiration, water loss and fast ripening ability result in shorter shelf life and ...

Critical Influence of Adsorption Geometry in the Heterogeneous Epoxidation of “Allylic” Alkenes:  Structure and Reactivity of Three Phenylpropene Isomers on Cu(111)

open access: yes, 2016
It has long been conjectured that the difficulty of heterogeneously epoxidizing higher alkenes such as propene is due to the presence in the molecule of “allylic” H atoms that are readily stripped off by the oxygenated surface of the metal catalyst ...

Antibacterial Activity of Estragole From Ocimum tenuiflorum, and Tagetes lucida and Synergistic Effect With Meropenem and Tobramycin Against Multidrug‐ and Extensively Drug‐Resistant (MDR‐XDR) Gram‐Negative Bacteria

open access: yesMicrobiologyOpen, Volume 15, Issue 1, February 2026.
This study reveals estragole's bactericidal activity against MDR/XDR Gram‐negative pathogens. Synergy with meropenem and tobramycin was observed in > 88% of strains, reducing antibiotic MICs up to 16‐fold. Estragole represents a promising therapeutic adjuvant to enhance antibiotic efficacy and combat antimicrobial resistance.
