A Direct, Biomass-Based Synthesis of Benzoic Acid: Formic Acid-Mediated Deoxygenation of the Glucose-Derived Materials Quinic Acid and Shikimic Acid [PDF]

open access: yes, 2010
An alternative biomass-based route to benzoic acid from the renewable starting materials quinic acid and shikimic acid is described. Benzoic acid is obtained selectively using a highly efficient, one-step formic acid-mediated deoxygenation ...

Histopathological investigation of wound healing activities of Lucilia sericata Larva and Achillea sintenisii extract combinations in diabetic rat wound model

open access: yesMedical and Veterinary Entomology, EarlyView.
Lucilia sericata larvae secrete bioactive compounds that promote wound debridement and antimicrobial defence in chronic tissue injuries. Achillea sintenisii extract offers phytotherapeutic support, enhancing healing through anti‐inflammatory and regenerative properties. Diabetic Wistar rats were treated topically with Furacin®, larval secretions, plant

In Vitro Gut Metabolism of [U-13C]-Quinic Acid, The Other Hydrolysis Product of Chlorogenic Acid

open access: yes, 2018
Scope: Quinic acid in its free form is broadly abundant in plants, and can accumulate in copious amounts in coffee, tea, and certain fruits. However, it has been mostly studied as chlorogenic acid, an ester of caffeic and quinic acids.

Diurnal Variations in Photochemical Energy Utilization and Osmotic Adjustments in Black Poplar Leaves Under Progressive Water Stress

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Drought limits the productivity of fast‐growing woody crops, although the metabolic adjustments conferring water stress tolerance remain poorly understood. We investigated the responses of Populus nigra seedlings to water stress by integrating daily physiological measurements and NMR metabolomic analyses.

An Efficient Transformation of (-)-Quinic Acid into Carba-L-Rhamnose

open access: yes, 2004
A novel stereoselective synthesis of carba-L-rhamnose from (-)-quinic acid is described. The title compound is obtained with an appropriate pattern of protecting groups to be used for the preparation of Streptococcus pneumoniae type 19F capsular ...

Rhizobacteria‐Induced Systemic Priming Against Fungal Pathogens Involves Hydroxycinnamic Acid Amides

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT The rhizosphere, a narrow region of soil surrounding roots, contains diverse microorganisms with a composition that is distinct from the surrounding soil. Some rhizosphere bacteria can trigger a heightened state of immunity in the whole plant, termed Induced Systemic Resistance (ISR).

Caffeic Acid Derivatives from Eupatorium perfoliatum L.

open access: yesMolecules, 2008
From the ethyl acetate soluble fraction of a methanol/water extract of the herb Eupatorium perfoliatum L. (Asteraceae) six caffeic acid derivatives have been isolated and identified by 1D- and 2D-NMR spectroscopic data.
