Caffeic acid is a hydroxycinnamic acid that is cinnamic acid in which the phenyl ring is substituted by hydroxy groups at positions 3 and 4. Caffeic acid phenethyl ester, a coffee polyphenol, inhibits DNA methylation in vitro and in vivo Eur J Pharmacol. Acetic acid, on the other hand, is more vinegary and less pleasant. The mechanism underlying these effects is, however, still poorly understood. Coffee is the primary source of caffeic acid in the human diet. Many plants besides coffee contain chlorogenic acids. Improving the Recovery of Phenolic Compounds from Spent ... Caffeic acid is found in coffee, as its name might suggest, however it is chemically unrelated to caffeine and shares none of its stimulant actions in the body. However, it can be found in other food sources such as apples, artichoke . Caffeic acid produces antidepressive-like activity in forced-swim mice. Caffeic acid (3,4-dihydroxy-cinnamic acid) is an organic compound and a potent antioxidant. Caffeic acid is a chemical found in many plants and foods. This polyphenol is also present in a wide variety of foods. Figure 1. Coffee is the primary source of caffeic acid in the human diet. Coffee also contains chlorogenic acid, ferulic acid, and caffeic acid. Green (unroasted) coffee contains chlorogenic acids, and the roasting process breaks those down into quinic acid (whose flavor you can associate with quinine in tonic water) and caffeic acid. Caffeine and depression: Positive and negative effects It has also been used to determine its antioxidant activity by various assay methods. The Chemistry of Organic Acids in Coffee: Part 3. 30 Caffeic acid shows anxiolytic-like effects in rats running a maze, and it protects against H 2 O 2-induced oxidative damage of rat brain tissue. Recent studies suggested that caffeic acid exerts anticarcinogenic effects, but little is known about the underlying molecular mechanisms and specific target proteins. Figure 02: Caffeic Acid Chemical Structure. It exists in cis and trans forms; the latter is the more common. Caffeic acid in coffee is also suggested to be neuroprotective. 46.4.2 Caffeic Acid. Your body metabolizes chlorogenic acid into its component chemicals, quinic acid and caffeic acid. The total content (covalently linked and free) of ferulic, caffeic, p-coumaric and chlorogenic acids was 5276 mg per kg of coffee pulp. Wine also contains a significant amount of caffeic acid. In the last issue we briefly discussed the role of quinic, caffeic, and citric acid and its role in coffee's flavor. Given that one of the main causes of HCC is hepatitis C virus (HCV) infection, we examined the effect of caffeic acid, a major organic acid derived from coffee, on the propagation of HCV using an in vitro naïve HCV particle-infection and production system within human . Furthermore, chlorogenic and caffeic acid were also quantified by using HPLC. Wine also contains a significant amount of caffeic acid.

Caffeic acid and chlorogenic acid are catechol-containing coffee polyphenols that, in a similar way to the tea polyphenols, have shown to be demethylating agents. While chlorogenic acid has a bitter taste, quinic acid and caffeic acid both have an even more pronounced bitter, astringent flavor. It exists in cis and trans forms; the latter is the more common. Tartaric acid is more grape-like, although it also appears quite heavily in bananas. Many plants besides coffee contain chlorogenic acids.
