The LC-MS/MS system consisted of a LCQ Advantage Finnigan instrument with ion-trap mass spectrometer equipped with an electrospray ionization (ESI) interface, and a Surveyor HPLC unit consisting of an autosampler/injector, quaternary pump, column heater, and diode array detector operated by Xcalibur software (Thermo Finnigan Corp). A Zorbax column (SB-C18 5µm 2.1x 150 mm column, Agilent) was used for the separation of analytes using a gradient elution condition by increasing the percentage of acetonitrile (with 1% acetic acid) in water (with 1% acetic acid) from 2% to 25% in 25 minutes at a flow rate of 0.2 mL/min. The MS conditions for the detection of ellagic acid and punicalagin A/B were as follows: ESI in negative mode; scan range 200 to 1200 amu; scan rate 1scan/second; cone voltage 17 eV. The identity of ellagic acid and punicalagin A/B was determined by matching the peak retention time and molecular ions [M-H]- obtained by ESI/MS and tandem mass spectrometry (MS-MS) with the expected theoretical molecular weights and the data from literature (Nunez-Sanchez MA et al 2014). The deprotonated [M-H]- ions were m/z 301 and 1083, and the fragment ions were m/z 257, 229 and 781, 601 for ellagic acid and punicalagin A/B, respectively. Nunez-Sanchez, M.

This review examines studies with both human subjects and animals on the absorption of these compounds, and their glucuronide, sulphate and methylated metabolites, into the cir- culatory system from the gastrointestinal tract and the evidence for their localisation within the body in organs such as the brain and eyes. The involvement of the colonic microflora in catabolising dietary flavonoids that pass from the small to the large intestine is discussed along with the potential fate and role of the resultant phenolic acids that can be produced in substantial quantities. The in vitro and in vivo bioactivities of these , subject to the Cambridge Core terms of use, available at polyphenol metabolites and catabolites are assessed, and the current evidence for their involvement in the protective effects of dietary polyphenols, within the gastrointestinal tract and other parts of the body to which they are transported by the circulatory system, is reviewed.

  • The Use of Pomegranate (Punica Granatum L.) Phenolic Compounds As Potential Natural Prevention Against Ibds
    15 The Use of Pomegranate (Punica granatum L.) Phenolic Compounds as Potential Natural Prevention Against IBDs Sylvie Hollebeeck, Yvan Larondelle, Yves-Jacques Schneider and Alexandrine During Institut des Sciences de la Vie, UCLouvain, Louvain-la-Neuve Belgium 1. Introduction Phenolic compounds (PCs) are plant secondary metabolites that are integral part of the “normal” human diet. The daily intake of PCs depends on the diet but is commonly evaluated at ca. 1g/day for people who eat several fruits and vegetables per day (Scalbert & Williamson, 2000). PCs may be interesting to prevent the development of inflammatory diseases, more particularly in the gastrointestinal tract, where their concentration may reach levels of up to several hundred µM (Scalbert & Williamson, 2000). Many studies have indeed reported on anti-inflammatory properties of different PCs (see (Calixto et al., 2004; Rahman et al., 2006; Romier et al., 2009; Shapiro et al., 2009), for reviews). Pomegranate (Punica granatum L.) belongs to the Punicaceae family, which includes only two species. More than 500 cultivars of Punica granatum exist with specific characteristics such as fruit size, exocarp and aril color, etc. Originating from the Middle East, pomegranate is now widely cultivated throughout the world, and also widely consumed. Pomegranate has been used for centuries in the folk medicine of many cultures. As described in the review of Lansky et al. (2007), the bark and the roots are believed to have anthelmintic and vermifuge properties, the fruit peel has been used as a cure for diarrhea, oral aphthae, and as a powerful astringent, the juice as a blood tonic, and the flowers as a cure for diabetes mellitus.

Ellagitannins belong to the class of hydrolysable tannins, they are esters of hexahydroxydiphenoic acid and monosac- charide (most commonly glucose). Ellagitannins are slowly hydrolysed in the digestive tract, releasing the ellagic acid molecule. Their chemical structure determines physical and chemical properties and biological activity. Ellagitannins occur naturally in some fruits (pomegranate, strawberry, blackberry, raspberry), nuts (walnuts, almonds), and seeds. They form a diverse group of bioactive polyphenols with anti-infl ammatory, anticancer, antioxidant and antimicrobial (antibacterial, antifungal and antiviral) activity. Furthermore, they improve the health of blood vessels. The paper discusses the metabolism and bioavailability of ellagitannins and ellagic acid. Ellagitannins are metabolized in the gastrointestinal tract by intestinal microbiota. They are stable in the stomach and undergo neither hydrolysis to free ellagic acid nor degradation. In turn, ellagic acid can be absorbed in the stomach. This paper shows the role of cancer cell lines in the studies of ellagitannins and ellagic acid metabolism. The biological activity of these compounds is broad and thus the focus is on their antimicrobial, anti-infl ammatory and antitumor properties.

The aim of this study was to isolate and Downloaded from have been shown to undergo extensive metabolism by gut micro- structurally characterize urolithin conjugates from the urine of a biota. Ellagitannins, which are high molecular polyphenols, are volunteer who ingested ellagitannin-rich natural products, and to metabolized to dibenzo[b,d]pyran-6-one derivatives—urolithins. evaluate the potential role of b-glucuronidase–triggered cleavage These compounds, in contrast with their parental compounds, have in urolithin disposition. Glucuronides of urolithin A, iso-urolithin A, good bioavailability and are found in plasma and urine at micromo- and urolithin B were isolated and shown to be cleaved by the lar concentrations.

Similarly, the parent molecules, ET and EA are reported for their neuroprotection and antidepressant activities. Due to the poor bioavailability of ET and EA, the in vivo functional activities cannot be attributed exclusively to these compounds. Elevated monoamine oxidase (MAO) activities are responsible for the inactivation of monoamine neurotransmitters in neurological disorders, such as depression and Parkinson’s disease. In this study, we examined the inhibitory effects of urolithins (A, B and C) and EA on MAO activity using recombinant human MAO-A and MAO-B enzymes. Urolithin B was found to be a better MAO-A enzyme inhibitor among the tested urolithins and EA with an IC50 value of 0.88 µM, and displaying a mixed mode of inhibition.
