Introduction Recently, there is an increased awareness on metabolic syndrome – a condition characterized by a group of metabolic risk factors in one person. They include abdominal obesity, atherogenic dyslipidemia, elevated blood pressure, insulin resistance, prothrombotic state & proinflammatory state. The dominant underlying risk factors appear to be abdominal obesity and insulin resistance. In addition, non-alcoholic fatty liver disease (NAFLD) is the most commonly associated “liver” manifestation of metabolic syndrome which can progress to advance liver disease (e.g. cirrhosis) with associated morbidity and mortality. Lifestyle therapies such as weight loss significantly improve all aspects of metabolic syndrome, as well as reducing progression of NAFLD and cardiovascular mortality. Walnut (Juglans regia L. seed) is one the most popular nuts consumed in the world. It is loaded in polyunsaturated fatty acids – linoleic acid (LA), oleic acid and α-linolenic acid (ALA), an ω3 fatty acid. It has been used since ancient times and epidemiological studies have revealed that incorporating walnuts in a healthy diet reduces the risk of cardiovascular diseases. Recent investigations reported that walnut diet improves the function of blood vessels and lower serum cholesterol. -

Presently, it is utilized not only for the exterior appearance of its fruit but above all, for the nutritional and health characteristics of the various parts composing this last one (carpellary membranes, arils, seeds and bark). The fruit, the pomegranate, is rich in numerous chemical compounds (flavonoids, ellagitannins, proanthocyanidins, mineral salts, vitamins, lipids, organic acids) of high biological and nutraceutical value that make it the object of study for many research groups, particularly in the pharmaceutical sector. -

Ellagitannin–Lipid Interaction by HR-MAS NMR Spectroscopy
molecules Article Ellagitannin–Lipid Interaction by HR-MAS NMR Spectroscopy Valtteri Virtanen * , Susanna Räikkönen, Elina Puljula and Maarit Karonen Natural Chemistry Research Group, Department of Chemistry, University of Turku, FI-20014 Turku, Finland; [email protected] (S.R.); [email protected] (E.P.); maarit.karonen@utu.fi (M.K.) * Correspondence: vtjvir@utu.fi; Tel.: +358-29-450-3205 Abstract: Ellagitannins have antimicrobial activity, which might be related to their interactions with membrane lipids. We studied the interactions of 12 different ellagitannins and pentagalloylglucose with a lipid extract of Escherichia coli by high-resolution magic angle spinning NMR spectroscopy. The nuclear Overhauser effect was utilized to measure the cross relaxation rates between ellagitannin and lipid protons. The shifting of lipid signals in 1H NMR spectra of ellagitannin–lipid mixture due to ring current effect was also observed. The ellagitannins that showed interaction with lipids had clear structural similarities. All ellagitannins that had interactions with lipids had glucopy- ranose cores. In addition to the central polyol, the most important structural feature affecting the interaction seemed to be the structural flexibility of the ellagitannin. Even dimeric and trimeric ellagitannins could penetrate to the lipid bilayers if their structures were flexible with free galloyl and hexahydroxydiphenoyl groups.

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. -

Indeed edible vegetables and fruits contain a wide variety of phytochemicals with proven antioxidant, anti-carcinogenic, and chemopreventive activity; moreover, some of these phytochemicals also display direct antiproliferative activity towards tumor cells, with the additional advantage of high tolerability and low toxicity. The most important dietary phytochemicals are isothiocyanates, ellagitannins (ET), polyphenols, indoles, flavonoids, retinoids, tocopherols. Among this very wide panel of compounds, ET represent an important class of phytochemicals which are being increasingly investigated for their chemopreventive and anticancer activities.
