CAFFEOYLQUINIC ACIDS BIOSYNTHESIS AND ACCUMULATION IN CYNARA CARDUNCULUS: STATE OF THE ART

Acta Horticulturae, 2013
Plant secondary metabolites are highly evolved compounds performing different functions, and have been widely exploited from food to medicine. A constant supply of phenols, a class of secondary metabolites, provides preventive and defensive mechanisms to reduce the risk of chronic diseases in human beings; among them mono- and di-caffeoylquinic acids ...

Covalent interactions between proteins and oxidation products of caffeoylquinic acid (chlorogenic acid)

Journal of the Science of Food and Agriculture, 2007
AbstractBACKGROUND: The interactions between phenolic compounds and proteins can modify protein properties important in the food industry. To understand the effects of these interactions, the covalent interactions between caffeoylquinic acid (chlorogenic acid, CQA) oxidised by polyphenol oxidase (PPO) at acidic pH 6 (pH 6) and α‐lactalbumin, lysozyme ...

Neuroprotective Caffeoylquinic Acid Derivatives from the Flowers of Chrysanthemum morifolium

Journal of Natural Products, 2017
Three new caffeoylquinic acid derivatives, chrysanthemorimic acids A-C (1-3), and 11 known compounds (4-14) were isolated and characterized from the flowers of Chrysanthemum morifolium. Their structures were confirmed by spectroscopic data as well as by comparison of the experimental and calculated electronic circular dichroism spectra ...

A comparative genotoxicity study of chlorogenic acid (3-0-caffeoylquinic acid).

Mutation research, 1982
Chlorogenic acid, a compound which occurs naturally in many food items, was assayed for genotoxic activity in 3 different test systems: reverse mutations in the preincubation test with Salmonella typhimurium, gene conversion with Saccharomyces cerevisiae strain D7, and chromosome aberrations in Chinese hamster ovary (CHO) cells.
