Despite this, the results suggested that the interference of non-phenolic compounds on the ORAC index was less than that xompuestos values of phenolic and flavonoid compounds. Therefore, glucuronidation is one of the main conjugation reactions of phenolic compounds metabolism in humans High dietary intake of fruits, vegetables and cereals are related to a decreased rate in chronic diseases.

Additionally, the diet of each host is diverse, because of this every host responds in a different way to phenolics.

Oxid Med Cell Longev. Methylation of dietary flavones increases their metabolic stability and chemopreventive effects. Phenolic compounds are receiving much attention because fenokicos their antioxidant properties.

Previous studies of quillay honey conducted by our investigation group showed the presence of compounds such as chlorogenic acid, caffeic acid, syringic acid, p-coumaric acid, gallic acid, quercetin, rutin and naringenin Montenegro et al.

A tendency of the flavonoids content was not observed within origin and type of accession.

Bioavailability is related to other two concepts: Differences between phenolic content and antioxidant capacity of quillay Chilean honeys and their separated phenolic extracts. The acylated flavonoids such as epicatechin and epicatechingallateare absorbed without prior hydrolysis or deconjugation 4, Analysis of Phenolic Plant Metabolites.

Today, the food matrix is considered as the factor most decisive in the bioavailability and absorption of dietary polyphenols A whole-grain cereal-based diet lowers postprandial plasma insulin and triglyceride levels in individuals with metabolic syndrome.

The four polyphenol groups predominant in apples are flavanols, phenolic acids, dihydrochalcones and flavonols Bioavailability fenolkcos on proper absorption, the release of a dosage form and presystemic elimination. Recovery vompuestos polyphenols from the by-products of plant food processing and application as valuable food ingredients. Phenolic compounds constitute a large and an important group of phenylpropanoids produced by plants as secondary metabolites. Crit Rev Food Sci Nutr.

Most cereal phenolics have covalent interactions with glycosides from the cell wall, forming ester linkages which are not hydrolysed by Phase I and II biotransformation enzymes, this limiting their release into the colon to be metabolized by intestinal microbiota 74, Citrus fruits are rich in various nutrients, such as vitamins A and C, folic acid and dietary fiber.

Int J Food Sci Nutr. Polyphenols in health and disease: Fong and Bauman point out that the composition profile of phenolics in European hawthorn species also suggest that flavonoids were the markers for the differentiation of C.

Dietary polyphenols and the prevention of fenolicoa. This showed the elution with methanol of these compounds together with phenolic compounds using an Amberlite XAD-2 column.

Flavonoids of Crataegus microphylla. The structure and distribution of the flavonoids in plants. Estimation of total flavonoids content in propolis by two complementary colorimetric methods. Micronutrients and Phytochemicals in Wheat Grain. The phenolic content was significantly higher in entire honeys Factors affecting the bioavailability of dietary phenolic compounds In nutrition science, bioavailability is defined as the fraction of an ingested compuwstos or compound that reaches the systemic circulation and the specific sites where it can exert its biological action.

Effect of Consumption of Phenolics on Human Health. For example, ecotypes of Crataegus azarolus collected in different regions of Italy febolicos variation in the sugar phenolic content of their fruits Bignami et al. Disintegration of wheat aleurone structure has an impact on the bioavailability of phenolic compounds and other fenollcos as evidenced by altered urinary metabolite profile of diet-induced obese mice. J Agric Fenolcos Chem. Am J Clin Nutr. Characterisation of polyphenols and antioxidant properties of five lettuce varieties and escarole.


Moreover, aglycones lipophilicity is higher than flavonoids glycosides, therefore they can be more readily absorbed.

It has been suggested that phenolic compounds play a significant role in the prevention of many chronic diseases due to their feonlicos, anti-inflammatory and anti-carcinogenic properties 7.

Transepithelial transport of rosmarinic acid in intestinal Caco-2 cell monolayers. Phenolic compounds have received considerable attention because their dietary intake is related to lower incidence of chronic diseases, such as cancer, diabetes, Alzheimer’s disease and cardiovascular diseases. Phenolics in Fruits and Their Relationship With Health Apples are one of the most popular fruits whose health benefits are attributed to phenolic compounds. Therefore, the substrates for glucuronidation contain functional groups such as aliphatic alcohols and phenols forming ethers O-glucuronide In fact, reductive sugars such as fructose, glucose, and sucroseorganic acids such as ascorbic, citric, and tartaric acidsferrous sulfate, and sodium sulfite are all potentially capable of interfering with the assessment of phenolic compounds in food matrixes by the FC assay Lester et al.

The major sites of flavonoid metabolism are the liver and the colonic flora.
