Antioxidative mechanisms in chlorogenic acid
Food Chemistry, 2017Although chlorogenic acid (5CQA) is an important ingredient of various foods and beverages, mechanisms of its antioxidative action have not been fully clarified. Besides electron spin resonance experiment, this study includes thermodynamic and mechanistic investigations of the hydrogen atom transfer (HAT), radical adduct formation (RAF), sequential ...

Antigenic properties of chlorogenic acid
Journal of Allergy, 1964Abstract Rabbits sensitized to chlorogenic acid by means of intramuscular and foot pad injections with chlorogenic acid emulsified in complete Freund's adjuvant showed positive Arthus reactions to chlorogenic acid and to green coffee extract. Sera obtained from the sensitized rabbits gave positive PCA reactions to chlorogenic acid and contained ...

The chlorogenic acids of Hemerocallis
Food Chemistry, 2006The chlorogenic acids in a methanolic extract of freeze-dried Hemerocallis (Chinese day lily) have been qualitatively profiled by LC–MS3. Three caffeoylquinic acids (3-CQA (I), 4-CQA (III) and 5-CQA (II)), three p-coumaroylquinic acids (3-pCoQA (IV), 4-pCoQA (VI) and 5-pCoQA (V)) and two feruloylquinic acids (3-FQA (VII) and 4-FQA (IX)) have been ...

ABSTRACT Chlorogenic acid at 5° published threshold concentration (100 mg/ L) in aqueous 0.2% potassium acid tartrate was not significantly more bitter than aqueous 0.2% potassium tartrate alone when evaluated by taste panel.

Chlorogenic Acid as a Natural Scavenger for Hypochlorous Acid
Biochemical and Biophysical Research Communications, 1995The effect of chlorogenic acid (CGA) on the killing of Escherichia coli by hypochlorous acid (HOCI) was examined. CGA prevented E. coli from bactericidal action of HOCI in a concentration-dependent manner. HOCI reacted rapidly with CGA. By comparison with the one- and two-electron oxidation products produced by peroxidase and phenolase reactions ...

On the variability of chlorogenic acid concentration
Oecologia, 1972The plasticity of phenolic acid concentration in plants under various physiological stress situations raises questions concerning the ecological significance of such behavior. Helianthus annuus L. is remarkably plastic with regard to chlorogenic and ischlorogenic acid concentrations when subjected to nitrogen deficiency, NaCl-stress, short exposures to

Chlorogenic acid-protein interactions in sunflower
Journal of Agricultural and Food Chemistry, 1974Phenolic compounds in Commander, Majak and Valley sunflowers varied between 3.0 and 3.5g of chlorogenic acid per 100 g of flour. Under neutral and alkaline conditions, sunflower protein solutions develop dark green and brown colors because of bonding with oxidation products of polyphenolic compounds, especially chlorogenic acid.

Chlorogenic acid composition of instant coffees
The Analyst, 1984A method, based on high-performance liquid chromatography, is described for the determination of chlorogenic acid isomers in instant coffee. Identification of the individual components was assisted by the preparation of isomeric mixtures by the isomerisation of available compounds and quantification based on published ultraviolet molar absorptivities ...

Determination of Chlorogenic Acid
Nature, 1957SLOTTA AND NEISSER1 found that o-dihydroxy-phenolic compounds such as chlorogenic acid and caffeic acid could be oxidized quantitatively with an alkaline hypoiodate solution, and used this method for the determination of these acids in coffee. They found that for every mole of chlorogenic or caffeic acid, 10 gm.-atoms of iodine were required for ...

Cognitive and neuroprotective effects of chlorogenic acid
Nutritional Neuroscience, 2016The aim of this review was to provide an overview of studies conducted to determine the effects of chlorogenic acid (CGA) on cognition and neurological health.A literature search was conducted using PubMed and various search terms including chlorogenic acid, CGA, memory, neuroscience, cognition, nutrition, antioxidant, pharmacokinetics, neuroprotection,
