But although both coffee and tea contain high levels of antioxidants, coffee tends to contain higher levels of the simple phenolics whereas tea larger levels of catechins.

Discoloration and Organic Matter Removal from Coffee Wastewater by Electrochemical Advanced Oxidation Processes. The findings indicate that treatment with chlorogenic acid could protect against neurological degeneration associated with oxidative stress in the brain.493 Chlorogenic acid significantly improved the impairment of short-term or working memory induced by scopolamine and significantly reversed cognitive impairments and decreased escape latencies in mice.

reported that decaffeinated green coffee beans had higher content of CGAs than regular green coffee beans of the same species (C. arabica).33 Indeed, the contents of total CGAs, CQAs, and FQAs of decaffeinated green coffee beans were approximately each 1.2 times higher than those of regular ones (Table 21.1).33 However, no significant differences in the content of diCQAs were detected (Table 21.1).33 The decaffeination process increased the contents of 3-CQA, 4-CQA, 3-FQA, 4-FQA, 3,4-diCQA, and 4,5-diCQA by 269%, 187%, 346%, 49%, and 24% w/w dry matter, respectively.

LC–MS can outperform HPLC–UV in high-sensitivity analyses to detect previously undetectable and unidentified trace constituents in green coffee beans.25–29 Specifically, 82 CGAs were detected in green coffee beans using this method (Figure 21.1).25–28 Clifford et al.

Structurally, chlorogenic acid is the ester of caffeic acid with the 3-hydroxyl group of quinic acid.Chlorogenic acid is an important factor in plant metabolism.

ex vivo, chlorogenic acid was shown to inhibit AChE activity in the hippocampus and frontal cortex, indicating that it may exert antiamnesic activity.494, Feifei Wei, Masaru Tanokura, in Coffee in Health and Disease Prevention, 2015, Chlorogenic acids are a family of esters formed between quinic acid and certain trans-cinnamic acids, most commonly caffeic, p-coumaric, and ferulic acid.

While it is of general knowledge that bile is an important excretion route for phenolic compounds and that this promotes enterohepatic recirculation,8,9,21,22b,29 no significant difference in CGA profile was observed when the 87 gastrointestinal fluid samples with pH varying from 2.0 to 7.8 were compared.29 The lack of difference between concentrations observed in gastric and intestinal fluids suggests that not only bile ( and possibly pancreatic fluid), but also gastric fluid plays a role in the recirculation of coffee CGA.
