Abstract

Chlorogenic acid (5-O-caffeoylquinic acid) is a phenolic compound from thehydroxycinnamic acid family. This polyphenol possesses many health-promoting properties, mostof them related to the treatment of metabolic syndrome, including anti-oxidant, anti-inflammatory,antilipidemic, antidiabetic, and antihypertensive activities. The first part of this review will discussthe role of chlorogenic acid as a nutraceutical for the prevention and treatment of metabolicsyndrome and associated disorders, including in vivo studies, clinical trials, and mechanisms ofaction. The second part of the review will be dealing with the role of chlorogenic acid as a foodadditive. Chlorogenic acid has shown antimicrobial activity against a wide range of organisms,including bacteria, yeasts, molds, viruses, and amoebas. These antimicrobial properties can beuseful for the food industry in its constant search for new and natural molecules for thepreservation of food products. In addition, chlorogenic acid has antioxidant activity, particularlyagainst lipid oxidation; protective properties against degradation of other bioactive compoundspresent in food, and prebiotic activity. The combination of these properties makes chlorogenic acidan excellent candidate for the formulation of dietary supplements and functional foods.

Antimicrobial properties of phenolic compounds from berries.

R Puupponen-Pimiä, L Nohynek, C Meier … (2001)

To investigate the antimicrobial properties of phenolic compounds present in Finnish berries against probiotic bacteria and other intestinal bacteria, including pathogenic species. Antimicrobial activity of pure phenolic compounds representing flavonoids and phenolic acids, and eight extracts from common Finnish berries, was measured against selected Gram-positive and Gram-negative bacterial species, including probiotic bacteria and the intestinal pathogen Salmonella. Antimicrobial activity was screened by an agar diffusion method and bacterial growth was measured in liquid culture as a more accurate assay. Myricetin inhibited the growth of all lactic acid bacteria derived from the human gastrointestinal tract flora but it did not affect the Salmonella strain. In general, berry extracts inhibited the growth of Gram-negative but not Gram-positive bacteria. These variations may reflect differences in cell surface structures between Gram-negative and Gram-positive bacteria. Cloudberry, raspberry and strawberry extracts were strong inhibitors of Salmonella. Sea buckthorn berry and blackcurrant showed the least activity against Gram-negative bacteria. Different bacterial species exhibit different sensitivities towards phenolics. These properties can be utilized in functional food development and in food preservative purposes.

Engineering plants with increased levels of the antioxidant chlorogenic acid.

Sean Michael, Cathie Martin, Ricarda Niggeweg (2004)

The trend to view many foods not only as sustenance but also as medicine, so-called functional foods, is increasing. Phenolics are the most widespread dietary antioxidants, and among these, chlorogenic acid (CGA) accumulates to high levels in some crop plants. CGA acts as an antioxidant in plants and protects against degenerative, age-related diseases in animals when supplied in their diet. cDNA clones encoding the enzyme that synthesizes CGA, hydroxycinnamoyl-CoA quinate: hydroxycinnamoyl transferase (HQT), were characterized from tomato and tobacco. Gene silencing proved HQT to be the principal route for accumulation of CGA in solanaceous species. Overexpression of HQT in tomato caused plants to accumulate higher levels of CGA, with no side-effects on the levels of other soluble phenolics, and to show improved antioxidant capacity and resistance to infection by a bacterial pathogen. Tomatoes with elevated CGA levels could be used in foods with specific benefits for human health.

Antibacterial activity and mechanism of action of chlorogenic acid.

Zaixiang Lou, Hongxin Wang, Song Zhu … (2011)

In this study, the antibacterial activity and mechanism of action of chlorogenic acid against bacteria were assessed. The data from minimum inhibitory concentration (MIC) values showed that chlorogenic acid effectively inhibited the growth of all tested bacterial pathogens, and the MIC values were ranging from 20 to 80 μg/mL. An investigation into action mode of chlorogenic acid against the pathogen indicated that chlorogenic acid significantly increased the outer and plasma membrane permeability, resulting in the loss of the barrier function, even inducing slight leakage of nucleotide. The leakage of cytoplasmic contents was also observed by electron micrographs. These results supported our hypothesis that chlorogenic acid bound to the outer membrane, disrupted the membrane, exhausted the intracellular potential, and released cytoplasm macromolecules, which led to cell death.
