[29], It is also used as a matrix in MALDI mass spectrometry analyses.[30]. Formula; IUPAC identifier; CAS number; More options; NIST Data. Notice: This spectrum may be better viewed with a Javascript More recent data show that bacteria in the rats' guts may alter the formation of metabolites of Caffeic Acid. Enter the desired X axis range All rights reserved. errors or omissions in the Database. It exists in cis and trans forms; the latter is the more common. Database and to verify that the data contained therein have Caffeic acid. Caffeic acid has been shown to inhibit carcinogenesis, although other experiments show possiblecarcinogenic effects. )", "Dr. Duke's Phytochemical and Ethnobotanical Databases", "Chlorogenic acid and caffeic acid are absorbed in humans", "Nuts' New Aflatoxin Fighter: Caffeic Acid? This hydroxylation produces the caffeic acid ester of shikimic acid, which converts to chlorogenic acid. Also, caffeic acid treatment attenuated lipopolysaccharide (LPS)-induced sickness behaviour in experimental animals by decreasing both peripheral and central cytokine levels along with oxidative stress inflicted by LPS. The amount of caffeic acid is strongly dependent on the plant species. uses its best efforts to deliver a high quality copy of the It is also known as an antioxidant in vitro and also in vivo. [19] In the same study, high doses of combined antioxidants, including caffeic acid, showed a significant decrease in growth of colon tumors in those same rats. [6]. Caffeic acid, C9H8O4 is a naturally occurring phenolic compound, (formerly called a carbolic acid), which is found in many fruits, vegetables, and herbs, including coffee, although varying in amounts depending on the plant. intended to imply recommendation or endorsement by the National such sites. the library and The HardyDisk™ Caffeic Acid Disks are a modification of this rapid method and provide for the presumptive identification of Cryptococcus neoformans within four hours. [16], Caffeic acid has a variety of potential pharmacological effects in in vitro studies and in animal models, and the inhibitory effect of caffeic acid on cancer cell proliferation by an oxidative mechanism in the human HT-1080 fibrosarcoma cell line has recently been established. Next, fungal colonies were exposed to three compounds thought to be antioxidants: gallic acid, which has aflatoxin-combating impacts in walnuts, and chlorogenic acid and caffeic acid. Caffeate 3,4-dioxygenase is an enzyme that uses caffeic acid and oxygen to produce 3-(2-carboxyethenyl)-cis,cis-muconate. [17] [18]. Caffeine is a different compound than caffeic acid. [28] The developing chemistry is similar to that of catechol or pyrogallol. in these sites and their terms of usage. with the development of data collections included in Caffeic acid, C 9 H 8 O 4 is a naturally occurring phenolic compound, (formerly called a carbolic acid), which is found in many fruits, vegetables, and herbs, including coffee, although varying in amounts depending on the plant.. Caffeic acid has been shown to act as a carcinogenic inhibitor. and Informatics, NIST / TRC Web Thermo Tables, professional edition (thermophysical and thermochemical data), NIST Mass Spectrometry Data Center, William E. Wallace, director, Modified by NIST for use in this application. Standard Reference Data Act. Stars Caffeic Acid is still listed under older Hazard Data sheets [8] as a potential carcinogen because of two early experiments on rats and mice. jcamp-plot.js. that these items are necessarily the best available for the purpose.

[4], Both caffeic acid and chlorogenic acid have been shown to be absorbed in humans. Read what you need to know about our industry portal chemeurope.com. DNA methylation contributes to the growth of tumors and regulates the epigenetics of cells that are passed along with DNA to future generations [19]. its accompanying search program. on behalf of the United States of America. [27], Caffeic acid may be the active ingredient in caffenol, a do-it-yourself black-and-white photographic developer made from instant coffee. shall not be liable for any damage that may result from Caffeic acid can be esterified with quinic acid to form chlorogenic acid. No significant effect was noted otherwise.[1][7]. © 1997-2020 LUMITOS AG, All rights reserved, https://www.chemeurope.com/en/encyclopedia/Caffeic_acid.html, Your browser is not current. However, the EC number for this purported enzyme was deleted in 2007, as no evidence has emerged for its existence.[14]. Please see the following for information about The interactive spectrum display requires a browser with JavaScript and Caffeic acid, which is unrelated to caffeine, is biosynthesized by hydroxylation of coumaroyl ester of quinic acid (esterified through a side chain alcohol). The following components were used in generating the plot: Additonal code used was developed at NIST: available from the NIST/EPA/NIH Mass Spectral Library. caffeic acid: ChEBI ID CHEBI:36281: Definition A hydroxycinnamic acid that is cinnamic acid in which the phenyl ring is substituted by hydroxy groups at positions 3 and 4. [22][23] Other than caffeic acid being a thiamine antagonist (antithiamine factor), there have been no known ill effects of caffeic acid in humans. Data from NIST Standard Reference Database 69: The National Institute of Standards and Technology (NIST) [25] This browning is due to the conversion of o-diphenols into reactive o-quinones. Oral administration of high doses of caffeic acid in rats has caused stomach papillomas, leading to the perception of caffeic acid as carcinogenic. spectrum (can be printed in landscape orientation).
