Epidemiological studies suggest that the incidence of CVD and postmenopausal osteoporosis is low in the Mediterranean area, where herbs and nuts, among others, play an important role in nutrition. In the present study, we sought a role of walnuts (Juglans regia L.) in endothelial and bone-cell function. As the endothelial cell expression of adhesion molecules has been recognised as an early ste...

Two new ellagic acid glycosides, named stachyanthuside A (1) and B (6), have been isolated along with four known ellagic compounds (2-5) from the leaves of Diplopanax stachyanthus. The structures of the new compounds were established as 3'-O-methylellagic acid 4-O-beta--glucopyranoside (1) and 3,3',4'-tri-O-methylellagic acid 4-O-beta--(2'-acetyl)-glucopyranoside (6) on the basis of detailed sp...

BACKGROUND Punica granatum (pomegranate), an edible fruit originating in the Middle East, has been used as a traditional medicine for treatment of pain and inflammatory conditions such as peptic ulcer. The numerous risks associated with nonsteroidal anti-inflammatory drugs (NSAIDs) for treatment of pain and inflammation give rise to using medicinal herbs as alternative therapies. This study aim...

Background and Objective: Alzheimer’s disease (AD) is a multifactorial disease with debilitating consequences and few therapeutic strategies exist for it. With regard to antioxidant capacity and anti-β-amyloid polymerization potential of ellagic acid, this study was conducted to evaluate the effect of this substance on enhanced acetylcholinesterase reactivity in an experimental model of Alzheim...

Objective: The present analysis deals with the effects of ellagic acid treatment and biochemical and histopathological alterations in mice with NaF-induced experimental chronic fluorosis. Materials and Methods: Treatments were carried out on male 28 Swiss albino mice divided into 4 equal groups for 8 weeks. Group I (control) was not applied experimental operation. Group II received subcutaneous...

The effects of four ellagitannin metabolites (M1-M4) and ellagic acid on immunoglobulin E-mediated allergic responses in rat basophilic leukemia-2H3 cells were investigated. M1-M4 inhibited the antigen-induced degranulation and secretion of interleukin-4 and tumor necrosis factor-α, but ellagic acid only slightly did so under the same experimental conditions. M1 inhibited the activation of the ...

In an effort to characterize active principles for diabetic complication from medicinal mushroom, aldose reductase inhibitors were isolated from the fruiting body of Phellinus linteus and identified as hispidin (5), phelligridimer A (6), davallialactone (7), methyldavallialactone (8), hypholomine B (9), interfungins A (10), and inoscavin A (11), together with protocatechuic acid (1), protocatec...

We performed a double-blind, placebo-controlled trial to clinically evaluate the protective and ameliorative effects of ellagic acid-rich pomegranate extract on pigmentation in the skin after ultraviolet ray (UV) irradiation, using female subjects in their 20s to 40s. Thirteen healthy volunteers per group were randomly assigned to three groups; namely, high dose (200 mg/d ellagic acid), low dos...

The ellagic acid, total phenolic, and vitamin C contents in four raspberry cultivars (Heritage, Autumn Bliss, Rubi, and Zeva) grown in Spain were detected and quantified by HPLC in fresh, just frozen, and stored fruits at -20 degrees C for a one year period. Ellagic acid [207-244 mg kg(-)(1) of fresh weight (fw)], total phenolic (137-1776 mg kg(-)(1) of fw), and vitamin C (221-312 mg kg(-)(1) o...

The bacteria Edwardsiella ictaluri and Flavobacterium columnare cause enteric septicemia and columnaris disease, respectively, in channel catfish (Ictalurus punctatus). Natural therapeutants may provide an alternative to current management approaches used by producers. In this study, a rapid bioassay identified plant compounds as potential therapeutants. Chelerythrine chloride and ellagic acid ...
