Nutr. Chlorogenic acid (CGA), a bioactive component in the human diet, is reported to exert beneficial effects on the regulation of glucose metabolism. 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.

FEBS Lett. reported that C. canephora had higher caffeine content than C. arabica, with contents of 2.54% and 1.22% (w/w dry matter, n = 38 samples), respectively.34 The three CGA isomer groups, CQAs, FQAs, and diCQAs, comprised 83%, 6%, and 11% and 73%, 11%, and 16% of total CGAs in C. arabica and C. canephora green coffee beans, respectively (Table 21.1). Separation and quantitation of isomeric caffeoylquinic acids in honeysuckle products by low-pH microemulsion electrokinetic chromatography using tartrate as a chiral selector. Research has suggested that the "di-CGA" form of the acid may be responsible to the bitter/metallic taste notes found in certain coffees. Chlorogenic acids are the most abundant of the many naturally occurring acids in green and roasted coffee beans; others include quinic, lactic, malic, citric, lactic and acetic acid. In contrast, those of 5-CQA, 5-FQA, and 3,5-diCQA decreased by 43%, 42%, and 35% w/w dry matter, respectively.33 These variations in the content of CGAs of decaffeinated green coffee beans may reflect the loss of water-soluble ingredients during the decaffeinating process.

Chlorogenic acid (CGA), a bioactive component in the human diet, is reported to exert beneficial effects on the regulation of glucose metabolism. Although the content of CQAs in C. canephora was only approximately 1.2 times higher than that in C. arabica, those of FQAs and diCQAs in C. canephora were approximately 3 times and 2 times higher than those in C. arabica, respectively (Table 21.1).10,31–35 When consumed as coffee, arabica coffee usually exceeds robusta coffee in organoleptic properties.
