Chitosan/Ellagic Acid Composite Materials for Local Cancer Therapy
… polymer was employed as a drug vehicle and ellagic acid (EA), a naturally occurring phenolic compound, was incorporated as a therapeutic agent. The chitosan/ellagic acid composite films were developed by combining 1% (w/v) chitosan solution with different concentrations (0.05, 0.1, 0.5, 1, …

Monomeric Ellagitannins in Oaks and Sweetgum
… phenolics characterized by biaryl-coupled gallic acid moieties esterified to a D-glucose core. They are widely distributed through higher plants. In the case of oaks, ellagitannin concentrations in heartwood can reach up to 10% (dry wt. basis). These secondary metabolites are not only important …

Naturally Derived Biocompatible Photoinitiators for 3D Printing
… Chapter 4 demonstrates a pomegranate-extracted ellagic acid as a water-soluble photoinitiator. Ellagic acid exhibits its light absorption in violet-cyan light range in alkali environments. Even though this finding is similar to the one of naringin, in identical conditions, ellagic acid can reach …

Characterisation of phenolic antioxidants in fruits and vegetables : bioavailability of raspberry phenolics in humans and rats
… of anthocyanins, ellagitannins and ellagic acid in raspberries was investigated. Plasma and urine were collected from six healthy human subjects after ingestion of 300 g of raspberries. Three healthy volunteers with an ileostomy were included in the study, providing ileal fluid, …

A MUSCADINE GRAPE EXTRACT PREVENTS HYPERTENSION-INDUCED CARDIAC AND VASCULAR DAMAGE IN ASSOCIATION WITH ANTI-FIBROTIC AND ANTIOXIDANT MECHANISMS
… and seeds are abundant in polyphenols including ellagic acid, gallic acid, and catechins. Previous studies demonstrated that muscadine grapes reduce cell proliferation and decrease inflammation. In these studies, we investigated the effects of a muscadine grape extract (MGE) on angiotensin II …

The nature of a constituent of quebracho tannin.
… which are hydrolysable and yield gallic acid. The second group consists of hydrolysable tannins which yield ellagic acid. The third group consists of non-hydrolysable tannins called phlobatannins. The latter yield red-colored insoluble products called "phlobaphenes" on boiling with acid. …

Effect of pomegranate extracts on apoptosis and cell cycle in haematological malignancies.
… fractions were enriched in ellagitannins, ellagic acid, and hydroxycinnamic acid derivatives but depleted in anthocyanins.The potential protective effect of a number of pure compounds that were either identified in the acetonitrile fraction of PJ were present in the other fractions of PJ or …

The Effects of Seizure Modeling and Polyphenols on Behavior in Bang-Sensitive Drosophila
… those observed in temporal lobe epilepsy (TLE). Ellagic acid (EA), a polyphenol present in several fruits and nuts, has shown beneficial effects in rodent models of epilepsy and anxiety, possibly mediated through GABAergic pathways. Bang-Sensitive Drosophila mutants model epileptic seizures …

Grape Extracts for Type 2 Diabetes Treatment Through Specific Inhibition of α-Glucosidase and Antioxidant Protection
… three phenolics from the GSE (resveratrol, ellagic acid, and catechin) were identified as active inhibitory compounds. The acute administration of GPE (400 mg/kg bw) to mice reduced postprandial blood glucose level by 35% following an oral glucose tolerance test compared to the control. The …

IN VITRO AND OMICS METHODOLOGIES APPLIED TO ANIMAL NUTRITION TO ADDRESS FEED-FOOD COMPETITION AND GREENHOUSE GAS EMISSIONS
… effect of two tannin compounds, called gallic acid (GA) and ellagic acid (EA), on the composition of the rumen microbial community and on the end products of enteric fermentation, with methane and ammonia production under the spotlight. To do this, we simulated rumen fermentation using two in …

Rapid separation of phenolic flavourings by liquid chromatography and nanomolar electrochemical detection at a boron-doped diamond electrode
… turned to the separation and detection of gallic acid (GA) and ellagic acid (EA) in whiskey. GA and EA are present in the oak casks used for maturation and so their presence can be used as markers of authentic whiskey. Chromatographic separation using a reversed-phase (RP) C18 column with gradient …

Effect of Dietary Factors on Mutagenesis, Metabolism, and Binding to DNA of Benzo [a] pyrene and Benzo [a] pyrene 7, 8-dihydrodiol
<p>Ellagic acid (EA), a naturally occurring plant phenol, at concentrations of 5 to 50 pg/plate, inhibited rat liver S9 protein dependent benzo[a]pyrene (B[a]P)-induced mutagenesis in Salmonella typhimurium TA 100 by 30-81% and B[a]P 7,8-dihydrodiol (DHD)-induced mutagenesis by 29 to 75%.
