Isolation, structure elucidation and neuroprotective effects of caffeoylquinic acid derivatives from the roots of Arctium lappa L.

open access: yesPhytochemistry, 2020
Five undescribed caffeoylquinic acid derivatives (CQAs), along with fifteen known CQAs, were isolated from the roots of Arctium lappa L.(burdock). The chemical structures of compounds were determined using extensive spectroscopic analyses, including UV ...

Microencapsulation of a Natural Antioxidant from Coffee—Chlorogenic Acid (3-Caffeoylquinic Acid)

open access: yesFood and Bioprocess Technology, 2017
Chlorogenic acids, the main polyphenolic group present in coffee, which include the caffeoylquinic acids, are recognized as antioxidants with growing interest in pharmacological, cosmetic, and food applications. However, they can be easily oxidized and they are also very unstable when exposed to high temperatures.

Evolution in Caffeoylquinic Acid Content and Histolocalization During Coffea canephora Leaf Development

open access: yesAnnals of Botany, 2006
Background and Aims Caffeoylquinic acids are cinnamate conjugates derived from the phenylpropanoid pathway. They are generally involved in plant responses to biotic and abiotic stress and one of them, chlorogenic acid (5-O-caffeoylquinic acid, 5-CQA), is

Physicochemical properties, antioxidant activities, and binding behavior of 3,5-di-O-caffeoylquinic acid with beta-lactoglobulin colloidal particles.

Food Chemistry, 2021
Milk proteins and polyphenols are increasingly being studied as functional ingredients due to the epidemiologically-proved health benefits. In this study, composite β-lactoglobulin (β-lg) or β-lactoglobulin nanoparticles (β-lgNPs)-3,5-di-O-caffeoylquinic
