The rates of oxidation of adenosine and chlorogenic acid by tert-butoxyl radicals (t-BuO) were studied by measuring the absorbance of adenosine at 260 nm and chlorogenic acid at 328 nm spectrophotometrically. t-BuO radicals were generated by the photolysis of tert-butyl hydroperoxide (t-BuOOH) in presence of tert-butyl alcohol to scavenge OH radicals. The rates and the quantum yields (phi) of o...

BACKGROUND Expression of cell adhesion molecules (CAM) on the endothelium and the attachment of monocytes to endothelium may play a major role in the early atherogenic process. Chlorogenic acid is a phenolic compound present in coffee, apples, pears, berries, almonds, artichokes, and aubergines. Previous studies have indicated that CA possesses antioxidant activity in vitro. AIM We investigat...

The aim of the study was to assess whether an extra fertilization with manganese, commercial fertilizer Alkalin (N, K and Si), and combined treatment (manganese + Alkalin) affect the chemical composition of chokeberry fruits (Aronia melanocarpa (Michx) Elliot), especially sugar content and the quantity and profile of phenolics. Dry weight, soluble solids, titratable acidity, total sugar, reduci...

chlorogenic acid, a pharmacologically important compound, is a phenolic compound that occurs in certain commonly used medicinal herbs. we looked for the presence of this compound in the callus cultures of varthemia persica dc (var. persica ). we have evaluated the conditions for establishment of callus cultures of v. persica and the in vitro production of chlorogenic acid. callus was initiated ...

in chlorogenic acid (5-caffeoylquinic acid) (Fig 1). Coffee, one of the most widely consumed beverages in the world, is the major dietary source of chlorogenic acids. Chlorogenic acid has antioxidant properties as shown by its ability to scavenge various free radicals when tested in vitro (3-5). Moreover, chlorogenic acid reduces glucose uptake by favouring the dissipation of the Na+ electroche...

A chlorogenic acid sensor based on a chitosan (CS) and multi-walled carbon nanotubes (MWCNTs) modified glassy carbon electrode (GCE) was fabricated via a layer-by-layer (LBL) self-assembly method. The prepared electrode exhibited excellent catalytic performance for chlorogenic redox reactions compared to the bare GCE. The effects of the number assembly layers, scan rate, pH of the supporting el...

BACKGROUND Chlorogenic acid is a potent phenolic antioxidant. However, its effect on platelet aggregation, a critical factor in arterial thrombosis, remains unclear. Consequently, chlorogenic acid-action mechanisms in preventing platelet activation and thrombus formation were examined. METHODS AND RESULTS Chlorogenic acid in a dose-dependent manner (0.1 to 1 mmol/L) inhibited platelet secreti...

Background and Objectives: Chlorogenic acid, a natural polyphenolic compound has been reported to possess neuroprotective and antioxidant activities, but the effect of chlorogenic acid on orofacial dyskinesia has not been explored till date, so the aim of the present study was to investigate the effect of chlorogenic acid on reserpine-induced orofacial dyskinesia in Wistar male albino rats. Met...

A high-performance liquid chromatographic method with gradient elution and diode-array detection was developed to quantify free phenolic acids (gallic, vanillic, chlorogenic, caffeic, syringic, p-coumaric, ferulic, sinapic, salycilic, elagic and trans-cinnamic), flavonoids (catechin, epicatechin, rutin, myricetin and quercetin) and juglone in walnut leaves. Chromatographic separation was perfor...
