Ellagic acid, a naturally occurring plant phenol, inhibits the activity of the direct-acting mutagen N-methyl-N-nitrosourea (MeNU) in Salmonella typhimurium TA100. Ellagic acid at 0.10, 0.25, 0.50, and 1.00 mM inhibited the mutagenicity of MeNU (0.40 mM) by 3%, 13%, 45%, and 60%, respectively. Ellagic acid (3 mM) also inhibited the mutagenic activity of N,N-dimethylnitrosamine (25-200 mM) in th...

objective: it is generally agreed that most of the phenomena observed during brain ischemia and reperfusion can be explained by the damage to membrane structure. oxidative stress is resulted in an imbalance between high consumption of oxygen and low levels of endogenous antioxidants. it is known that gallic acid (ga) is a strong antioxidant. the present study was carried out to evaluate the eff...

conclusions acute and chronic administration of ellagic acid had anxiolytic property. also, the most effective dose of ellagic acid was 30 mg/kg. pretreatment with flumazenil reversed the beneficial effect of ellagic acid and diazepam on anxiety. it is likely that the anxiolytic effect of ellagic acid is largely mediated by activation of gabaa receptor. results acute and chronic application of ...

Objective(s): Stroke poses a crucial risk for mortality and morbidity. Our study aimed to investigate the effect of p-coumaric acid on focal cerebral ischemia in rats. Material and Methods: Rats were randomly divided into four groups, namely Group I (control rats), Group II (ischemia rats), Group III (6 hr ischemia + p-coumaric acid rats) and Group IV (24 hr ischemia + p-coumaric acid rats). C...

OBJECTIVE In this study, β-cyclodextrin (β-CD) was chosen as the coating for ellagic acid to prepare ellagic acid microspheres, and the effect of microspheres on the growth of HepG2 cells was observed. METHODS Scanning electron microscopy, infrared spectroscopy, and release rate analysis were used to identify the formation of ellagic acid microspheres. Methyl thiazolyl tetrazolium (MTT) assay...

BACKGROUND Antioxidant, antiproliferative and apoptosis inducing activities of a natural polyphenolic compound, ellagic acid, were studied. MATERIALS AND METHODS DPPH radical scavenging and lipid peroxidation inhibitory activities were observed. Activities of antioxidant enzymes, superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPX) were measured in ellagic acid-treated ...

The health benefits associated with pomegranate juice have led to the development of pomegranate extracts as botanical dietary supplements. Pomegranates contain hydrolyzable tannins in the form of punicalagins and punicalin as well as tannin-based complex oligomers that account for much of the antioxidant activity in juice. The content of ellagic acid has been used to standardize most pomegrana...

Pomegranate and pomegranate juices (PJs) have taken great attention for their health benefits in the last years. As there is an increasing concern about potential health benefits of ellagic acid, it is of great interest to evaluate alterations in ellagic acid concentration of commercial PJs. The purpose of this study is to analyze total phenolic, free and total ellagic acid content of six comme...

Ellagic acid is a naturally occurring polyphenolic compound which is found in many fruits, nut galls and plant extracts. In the present study, we explored the ability of ellagic acid to modulate LPS response using macrophage-mediated inflammatory conditions and acute lung injury (ALI). Methods and Results: First, we found that ellagic acid reduced tumor necrosis factor-α (TNF-α), interleukin-6 ...

Ellagic acid has been proven to have anticancer, antimutation, antimicrobial and antiviral functions. The present study investigated whether treatment with ellagic acid was able to prevent tetrachloride (CCl4)-induced cirrhosis through the inhibition of reactive oxygen species (ROS) formation and angiogenesis. CCl4 diluted in olive oil at a final concentration of 10% was used to induce a cirrho...
