Lee and Zhu examined the effects of these two compounds on the methylation status of the RARβ gene promoter region of MCF-7 and MDA-MB-231 human breast cancer cells [88].The treatment of MCF-7 cells with 1, 5, 20, or 50 μM and the . Caffeic acid is a substance that is present in all plants, including vegetables, fruits, herbs, coffee beans, plant-based spices and others that we eat and drink. Caffeic acid (3,4-dihydroxycinnamic acid) is a well-known phenolic phytochemical present in many foods, including coffee. However, it can be found in other food sources such as apples, artichoke, berries, and pears. Caffeic Acid and chlorogenic acid from coffee beans both reduced DNA methylation in vitro in two lines of human cancer cells. It has a role as a plant metabolite, an EC 1.13.11.33 (arachidonate 15-lipoxygenase) inhibitor, an EC 2.5.1.18 (glutathione transferase) inhibitor, an EC 1.13.11.34 (arachidonate 5 . The total content (covalently linked and free) of ferulic, caffeic, p-coumaric and chlorogenic acids was 5276 mg per kg of coffee pulp. We can find caffeic acid in barley and rye grain at low levels. Caffeic acid is a chemical found in many plants and foods. Many plants besides coffee contain chlorogenic acids. Caffeic acid (3,4-hydroxycinnamic acid) is found in several grains, fruits, and vegetables 1.It also occurs in Coffea arabica (coffee beans), particularly in its esterified form, chlorogenic acid (5-caffeoylquinic acid). Multipurpose cohort studies have demonstrated that coffee consumption reduces the risk of hepatocellular carcinoma (HCC). It can be found naturally in a wide range of plants. Caffeic acid, an antioxidant, may boost collagen levels and reduce the premature aging of cells. However, it can be found in other food sources such as apples, artichoke . Caffeic acid produces antidepressive-like activity in forced-swim mice. Regular coffee intake may also reduce the risk of stroke. The highest chlorogenic acid was detected as 85.0 ± 0.6 mg/kg FW with UAE at 60% amplitude for 15 min. As a precursor of many biologically active polyphenols in Caffeic acid (3,4-dihydroxy-cinnamic acid) is an organic compound and a potent antioxidant. CGA is an ester formed between caffeic acid and quinic acid and is hydrolyzed into various aromatic acid metabolites including caffeic and salicylic acid [25, 35]. Figure 1. Specifications Sheet. Distribution was as follows (in %): chlorogenic acid 58.7 . Caffeic acid (CA), a coffee-related organic acid, is a degradation product of chlorogenic acid, abundant in coffee beans. Coffee is the primary source of caffeic acid in the human diet. Caffeic acid is a chemical found in many plants and foods. Antioxidant activity of ferulic and caffeic acids was studied both in vitro and in vivo. Other CGAs in coffee include dicaffeoylquinic, feruloylquinic and coumaroylquinic acid. This polyphenol is also present in a wide variety of foods. 46.4.2 Caffeic Acid. Caffeic acid (3,4-dihydroxycinnamic acid) is a well-known phenolic phytochemical present in many foods, including coffee. 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. Acids in the chlorogenic group have very similar structures, and make up a family of esters often including caffeic acid and quinic acids as components (Michael N. Clifford, 1999). 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. All of the chlorogenic acids fall into the larger category of phenolic acids (Flament, 2002). Wine also contains a significant amount of caffeic acid. Caffeic acid in coffee is also suggested to be neuroprotective. 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 . Figure 02: Caffeic Acid Chemical Structure. It is responsible for the deep aroma, color, and bitterness of coffee. There is a moderate level of caffeic acid in coffee, and it is a common natural phenol in argan oil. Welcome back to this third and final issue of organic acids. Recent studies suggested that caffeic acid exerts anticarcinogenic effects, but little is known about the underlying molecular mechanisms and specific target proteins. 46.4.2 Caffeic Acid. Caffeic acid has been used as a standard of phenolic acid in the study to determine the total phenolic acid content in vegetables after subjecting to alkaline and acid hydrolysis. This polyphenol is also present in a wide variety of foods. 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. All of the chlorogenic acids fall into the larger category of phenolic acids (Flament, 2002). 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. Chlorogenic acid was found as the main phenolic compound in spent coffee grounds (SCG). The Chemistry of Organic Acids in Coffee: Part 3. 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 is a chemical found in many plants and foods. It exists in cis and trans forms; the latter is the more common. Caffeic acid also has antimicrobial properties, which means that it may help protect the skin . Your body metabolizes chlorogenic acid into its component chemicals, quinic acid and caffeic acid. It is a member of a large class of . It exists in cis and trans forms; the latter is the more common. According to Olholf et al. Coffee is the primary source of caffeic acid in the human diet. 2.3. 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. [] about 95% of caffeic acid is absorbed in the first parts of the alimentary system in humans, i.e., in the stomach and/or small intestine.Most probably, in the stomach caffeic acid is absorbed by passive non-ionic mechanism, whereas in the small intestine, this compound can be absorbed via active transport. Acetic acid, on the other hand, is more vinegary and less pleasant. Caffeic acid (CA), a coffee-related organic acid, is a degradation product of chlorogenic acid, abundant in coffee beans. Ferulic acid presented in coffee has anti-inflammatory, anti-allergic, antibacterial, antiplatelet, and antiviral effect .

Coffee is the primary source of caffeic acid in the human diet. We can find caffeic acid in barley and rye grain at low levels. DNA methylation contributes to the growth of tumors and regulates the epigenetics of cells that are passed along with DNA to future generations. It is responsible for the deep aroma, color, and bitterness of coffee. The mechanism underlying these effects is, however, still poorly understood. Moreover, we can find this compound at high levels in herbs, including thyme, sage, and spearmint. These acids can reduce the inflammation of nerve cells that takes place in the brains of people with depression. Tartaric acid is more grape-like, although it also appears quite heavily in bananas.
