Summary Preparations of the previously unreported, water-soluble, tetraguanidinium, tetracholine and tetrakisbenzyltrimethylammonium ellagates are outlined. Ellagic acid and these water-soluble salts remove Mg2+, Ca2+ and Mn2+ ions from dilute aqueous solutions at pH greater than 7. The salts also remove Fe2+, Fe3+, Co2+ and Cu2+ between pH

Ellagitannins, ellagic acid and vascular health
Molecular Aspects of Medicine, 2010Hydrolysable tannins are phenolic phytochemicals that show high antioxidant and free-radical scavenging activities. For this reason their potential effects preventing oxidative related diseases, such as cardiovascular diseases, have been largely studied.

Neuroprotective Potential of Ellagic Acid: A Critical Review
Advances in Nutrition, 2021Ellagic acid (EA) is a dietary polyphenol present in various fruits, vegetables, herbs, and nuts. It exists either independently or as part of complex structures, such as ellagitannins, which release EA and several other metabolites including urolithins following absorption.

Spectrofluorimetric determination of ellagic acid in brandy
Food Chemistry, 2012Two spectrofluorimetric methods have been developed for the rapid determination of ellagic acid. The first method is based on the complex formation between ellagic acid and borax in methanol solution. The fluorescence of the complex is monitored at an emission wavelength of 456nm with excitation at 383nm.

Reaction between Ellagic Acid and an Ultimate Carcinogen
Journal of Chemical Information and Modeling, 2005The reaction coordinate between a typical ultimate carcinogen benzo[a]pyrene-7,8-diol-9,10-epoxide (BPDE) and ellagic acid, a proven chemopreventive agent active against cancers caused by polycyclic aromatic hydrocarbons (PAHs), was examined by density functional theory (DFT) and semiempirical MO calculations, and activation energy was calculated.

Terahertz spectrum of ellagic acid
2009 34th International Conference on Infrared, Millimeter, and Terahertz Waves, 2009The absorption and refractive index of ellagic acid in the range of 0.2–2.4 THz have been measured by THz-TDS. It is found that the ellagic acid has the fingerprint absorption in this frequency region. The vibration absorption spectrum of the single molecule of ellagic acid between 0.2 and 2.4 THz is simulated based on the Density Functional Theory ...

ABORTION IN MICE INDUCED BY ELLAGIC ACID
Acta Pathologica Microbiologica Scandinavica Section A Pathology, 1971Ellagic acid was injected intravenously into mice at day 8, 12, or 16 of pregnancy. In all animals given this treatment there was an increased frequency of abortion. Platelet‐fibrin masses were found in the lungs, in the great majority of the mice given ellagic acid at day 16 of gestation.

The Control of Bleeding in Splenectomized Animals by Ellagic Acid
Thrombosis and Haemostasis, 1967Summary1. Blood loss after splenectomy was reduced significantly by i. v. injection of ellagic acid.2. The duration of bleeding was also shortened significantly.3. There were no obvious toxic manifestations and no evidence of thrombosis.

Spectroscopic studies on the antioxidant activity of ellagic acid
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2014Ellagic acid (EA, C14H6O8) is a natural dietary polyphenol whose benefits in a variety of diseases shown in epidemiological and experimental studies involve anti-inflammation, anti-proliferation, anti-angiogenesis, anticarcinogenesis and anti-oxidation properties. In vitro radical scavenging and antioxidant capacity of EA were clarified using different

Augmentation of Radiation-Induced Apoptosis by Ellagic Acid
Cancer Investigation, 2009This study evaluates the potential of ellagic acid (EA) as an enhancer of radiation-induced apoptosis in cancer cells. HeLa cells treated with EA and gamma radiation showed increased superoxide generation, upregulated p53 protein expression, and decreased antioxidant enzymes.
