Absorption, excretion, and distribution of dietary antioxidant betalains in LDLs: potential health effects of betalains in humans. (1/2)

BACKGROUND: Betalains were recently identified as natural antioxidants. However, little is known about their bioavailability from dietary sources. OBJECTIVE: The objective was to evaluate the bioavailability of betalains from dietary sources. DESIGN: The plasma kinetics and urinary excretion of betalains were studied in healthy volunteers (n = 8) after a single ingestion of 500 g cactus pear fruit pulp, which provided 28 and 16 mg indicaxanthin and betanin, respectively. The incorporation of betalains in LDL and the resistance of the particles to ex vivo-induced oxidation was also researched. RESULTS: Betanin and indicaxanthin reached their maximum plasma concentrations 3 h after the fruit meal and declined according to first-order kinetics. The half-life of betanin (0.94 +/- 0.07 h) was shorter than that of indicaxanthin (2.36 +/- 0.17 h). Both compounds had disappeared from plasma by 12 h after intake. The urinary excretion of indicaxanthin and betanin over 12 h represented 76 +/- 3.0% and 3.7 +/- 0.2%, respectively, of the ingested compounds. LDL isolated 3 and 5 h after the fruit meal incorporated betalains at concentrations of 100.5 +/- 11 and 50 +/- 7.2 pmol/mg LDL protein, respectively. In addition, the particles appeared more resistant to ex vivo-induced oxidative injury than did the samples isolated before fruit ingestion (P < 0.05)-the higher the amount of betalains incorporated, the higher the resistance. The concentrations of vitamin E and beta-carotene in LDL did not change significantly after fruit ingestion. CONCLUSION: Our results show that cactus pear fruit is a source of bioavailable betalains and suggest that indicaxanthin and betanin may be involved in the observed protection of LDL against ex vivo-induced oxidative modifications.  (+info)

Antioxidants that inhibit oxidation are stable molecules produced by the host or from the dietary sources.. Free radicals are highly reactive and unstable atoms with a single electron on the outermost ring. To become stable, free radicals intercept or donate an electron from stable atoms, leading to a chain reaction that can not be stopped until all electrons on the outermost ring are paired or inhibited by antioxidants.. Oxidative stress is a result of overexpression of free radicals compared to low levels of antioxidants in the body. Over time, oxidative stress induces protein, lipid, and cellular damage, leading to cells injury and death that facilitate the onset of chronic diseases, including CVD and cancer.. However, free radicals at a moderate level are necessary for the body function, including maintaining the blood vessels in the regulation of relaxation and constriction.. Some diseases associated with free radicals ...

Betalains represent a natural and safe alternative to colour synthetic additives that are used currently in food industry. In addition to the colouring property, betalains are of particular interest because of their importance in health: antimicrobial and antioxidant activity, radio-protective, antiviral, anti-inflammatory and detoxifying effect. This study compares different classics methods of betalains extraction, using water and weak acid solutions from fresh, dried and lyophilized beetroot. The highest content of betanin (20 mg /g) has been obtained from lyophilized beet using 0.5% citric acid and 0.1% ascorbic acid as solvents. In this study temperature, pH, liquid/solid ratio were considered the main factors which influence the performance of extraction process and stability of betanin. The extraction is better at high temperatures (70 C), regardless of the other two parameters. At low temperature it is necessary to increase the liquid/solid ratio and decrease the pH for getting a good ...
The aim of study was investigation the impact of boiling and spontaneous fermentation on profile and content of betalains and antioxidant capacity of red beetroot. Betalains were analyzed by micro-HPLC-TOF-MS/MS method, while antioxidant capacity by three in vitro assays. Red beet products were abounded in betalains, with betanin, isobetanin, betanidin and vulgaxanthin I predominating among twenty two pigments identified. Boiling and fermentation of red beet reduced the content of betalains by 51-61% and 61-88%, respectively, however, this decline was limited when the peel was present. Microbial activity and softening of the matrix induced by the fermentation process led to the release of betalains responsible for strong antioxidant capacity of the juice formed. Generally, the treatment applied maintained and/or lowered antioxidant capacity of red beet materials obtained. Our findings indicate that red beet-derived products are valuable source of betalains, with their profile, content and ...

Condensed tannins may be characterised by a number of techniques including depolymerisation, asymmetric flow field flow fractionation or small-angle X-ray scattering. DMACA is a dye that is particularly useful for localization of proanthocyanidin compounds in plant histology. The use of the reagent results in blue staining.[17] It can also be used to titrate proanthocyanidins. Proanthocyanidins from field beans (Vicia faba)[18] or barley[19] have been estimated using the vanillin-HCl method, resulting in a red color of the test in the presence of catechins or proanthocyanidins. Proanthocyanidins can be titrated using the Procyanidolic Index (also called the Bates-Smith Assay). It is a testing method that measures the change in color when the product is mixed with certain chemicals. The greater the color changes, the higher the PCOs content is. However, the Procyanidolic Index is a relative value that can measure well over 100. Unfortunately, a Procyanidolic Index of 95 was erroneously taken to ...
