The effectiveness of chlorogenic acid and its main metabolites, caffeic
and quinic acids, against oxidative stress was investigated.
and sinapic acids reported in Anaheim pepper (Sandia cv.
The HPLC analysis revealed that flavonoids (quercetin, quercitrin, isoquercitrin, luteolin, rutin and kaempferol), tannins (caffeine, catechin, epicatechin and epigallocatechin) and phenolics acids (gallic, chlorogenic, ellagic and caffeic
acids) are present in the SBE (Fig.
uk, said: "Coffee contains chlorogenic acid and caffeic
acid, which have antioxidant properties that may help reduce inflammation and protect against chronic disease.
In addition to a structural role, lignin confers protection against pathogens and insects (Swain, 1979; El Modafar and El Boustani, 2004), while caffeic
, p-coumaric, ferulic and sinapic acids participate in cell wall composition, singly or in a range of sterified forms (Harborne, 1988).
Like olive oil, it also contains some vitamin E, along with small quantities of polyphenols such as caffeic
acid, oleuropein, catechol and resorcinol.
The results showed that among the phenylpropanoid metabolites, the variation trends of chlorogenic acid and flavonoids were similar, and caffeic
acid content remained stable in each period.
Furthermore, cucumbers have a high water content that helps lubricate joints, as well as vitamin C and caffeic
acid, both of which support skin integrity and reduce swelling.
Rosemary contains both caffeic
acid and rosmarinic acid which act as a powerful anti-inflammatory making it ideal for those who suffer with auto-immune disorders such as rheumatoid arthritis, chronic fatigue syndrome, and fibromyalgia.
acid was chosen as representative of the phenolic acids since it has also been demonstrated to be inhibitory on adipogenesis .
HPLC analysis indicated that the major polyphenols in the SFE extracts consisted of chlorogenic acid, caffeic
acid, syrigin, procyanidin B2, (-)-epicatechin, cinnamic acid, coumaric acid, phlorizin and quercetin, of which procyanidin B2 had the highest content of 231.
The major chemical constituents of the fruits of Berberis integerrima (barberry), of the Berberidaceae family, include coumarin, ascorbic acid, berberine, caffeic
acid, [beta]-carotene, flavonoids, malic acid, palmatine, carbohydrates, tannin, and ursolic acid.
