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. -

Although biologically sourced, TA is a pollutant in industrial wastewater streams, and there is desire to find applications in which to downcycle this molecule. Many flame retardants (FRs) used in epoxy are synthesized from petroleum-based monomers. Various bio-based modifiers have been developed, but increasing the flame retardancy of the system without trade-offs with other properties has proved challenging. In this work, TA is incorporated into the thermoset. The molecular behavior of the system was dependent on the TA loading, with low concentrations causing the molecule to be surface-functionalized, while at higher concentrations the molecule was cross-linked into the network. -

In the search for alternatives to synthetic preservatives, antioxidants from plants and herbs are increasingly being investigated for the preservation of food. In this study, extracts were prepared from Terminalia ferdinandiana fruit, leaves, seedcoats, and bark using different solvents. Hydrolysable and condensed tannin contents in the extracts were determined, as well as antioxidant capacity, by measuring the total phenolic content (TPC) and free radical scavenging activity using the 2, 2-diphenyl-1-picrylhydrazyl (DPPH) assay. Total phenolic content was higher in the fruits and barks with methanol extracts, containing the highest TPC, hydrolysable tannins, and DPPH-free radical scavenging capacity (12.2 2.8 g/100 g dry weight ± (DW), 55 2 mg/100 g DW, and 93% respectively). Saponins and condensed tannins were highest in ± bark extracts (7.0 0.2 and 6.5 0.7 g/100 g DW). -

Aos meus pais Beth e Miti. Eles não mediram esforços para que eu pudesse receber uma boa educação e para que eu fosse feliz. Logo no início da graduação, a situação financeira ficou bem apertada, mas eles continuaram fazendo de tudo para me ajudar. Foram milhares de favores prestados, marmitas e caronas. Meu pai diz que fez anos de curso de inglês e espanhol, porque passou anos acordando cedo no sábado só para me levar no curso que eu fazia no Fundão. Tinha dia que eu saía do curso morta de fome e quando eu entrava no carro, tinha uma marmita com almoço, com direito até a garrafa de suco. -
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.

ABSORPTION AND METABOLISM OF MANGO (MANGIFERA INDICA L.) GALLIC ACID AND GALLOYL GLYCOSIDES A Dissertation by RYAN CRISPEN BARNES Submitted to the Office of Graduate and Professional Studies of Texas A&M University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY Chair of Committee, Stephen Talcott Co-Chair of Committee, Susanne Talcott Committee Members, Nancy Turner Arul Jayaraman Head of Department, Boon Chew December 2016 Major Subject: Food Science and Technology Copyright 2016 Ryan Barnes ABSTRACT The composition, absorption, metabolism, and excretion of gallic acid, monogalloyl glucose, and gallotannins in mango (Mangifera indica L.) pulp were investigated. Each galloyl derivative was hypothesized to have a different rate of absorption, and their concentrations were compared in the pulp of five mango varieties. The cultivar Ataulfo was found to have the highest concentration of monogalloyl glucose and gallotannins while the cultivar Kent had the lowest. Enzymatic hydrolysis of gallotannins with tannase led to the characterization of six digalloyl glucoses and five trigalloyl glucoses that have the potential to be formed in the colon following gallotannin consumption. The bioaccessibility of galloyl derivatives was evaluated in both homogenized mango pulp and 0.65 mm3 cubes following in vitro digestion conditions. Monogalloyl glucose was found to be bioaccessible in both homogenized and cubed mango pulp. However, cubed mango pulp had a significantly higher amount of gallotannins still bound to the fruit following digestion. Gallic acid bioaccessibility significantly increased following digestion in both homogenized and cubed mango pulp, likely from hydrolysis of gallotannins. Additionally, for the first time, the absorption of monogalloyl glucose and gallic acid was investigated in both Caco-2 monolayer transport models and a porcine pharmacokinetic model with no significant differences found in their absorption or ability to produce phase II metabolites. -
Inhibitory Activities of Selected Sudanese Medicinal Plants On
Mohieldin et al. BMC Complementary and Alternative Medicine (2017) 17:224 DOI 10.1186/s12906-017-1735-y RESEARCH ARTICLE Open Access Inhibitory activities of selected Sudanese medicinal plants on Porphyromonas gingivalis and matrix metalloproteinase-9 and isolation of bioactive compounds from Combretum hartmannianum (Schweinf) bark Ebtihal Abdalla M. Mohieldin1,2, Ali Mahmoud Muddathir3* and Tohru Mitsunaga2 Abstract Background: Periodontal diseases are one of the major health problems and among the most important preventable global infectious diseases. Porphyromonas gingivalis is an anaerobic Gram-negative bacterium which has been strongly implicated in the etiology of periodontitis. Additionally, matrix metalloproteinases-9 (MMP-9) is an important factor contributing to periodontal tissue destruction by a variety of mechanisms. The purpose of this study was to evaluate the selected Sudanese medicinal plants against P. gingivalis bacteria and their inhibitory activities on MMP-9. Methods: Sixty two methanolic and 50% ethanolic extracts from 24 plants species were tested for antibacterial activity against P. gingivalis using microplate dilution assay method to determine the minimum inhibitory concentration (MIC). The inhibitory activity of seven methanol extracts selected from the 62 extracts against MMP-9 was determined by Colorimetric Drug Discovery Kit. In search of bioactive lead compounds, Combretum hartmannianum bark which was found to be within the most active plant extracts was subjected to various chromatographic (medium pressure liquid chromatography, column chromatography on a Sephadex LH-20, preparative high performance liquid chromatography) and spectroscopic methods (liquid chromatography-mass spectrometry, Nuclear Magnetic Resonance (NMR)) to isolate and characterize flavogalonic acid dilactone and terchebulin as bioactive compounds. Results: About 80% of the crude extracts provided a MIC value ≤4 mg/ml against bacteria. -
