A survey on five kinds of cocoa beans from new cocoa planting countries was conducted to analyze each kind's basic quality. The average bean weight and butter content of Hainan cocoa beans were the lowest, at less than 1.1 g, and 39.24% to 43.44%, respectively. Cocoa beans from Indonesia where shown to be about 8.0% and 9.0% higher in average bean weight and butter content, respectively, than t...

The aim of the study was to determine changes incurred by polyphenolic compounds from selected fruits in the lipid phase of the erythrocyte membrane, in liposomes formed of erythrocyte lipids and phosphatidylcholine liposomes. In particular, the effect of extracts from apple, chokeberry, and strawberry on the red blood cell morphology, on packing order in the lipid hydrophilic phase, on fluidit...

Various epidemiological studies have shown an inverse association between the consumption of polyphenols or polyphenol-rich foods and the risk of neurodegenerative, hepatic diseases. The research aimed to fight oxidative stress and lipid metabolism changes in the context of administration of antioxidants, such as polyphenolic extract of Aronia melanocarpa and zinc aspartate, known for its neuro...

OBJECTIVE The aim of this study was to evaluate the anti-inflammatory and analgesic effects of Satureja hortensis seed extracts and to analyze their essential oil constituents. MATERIALS AND METHODS Hydroalcoholic and polyphenolic extracts and essential oil of S. hortensis seeds were prepared using standard methods. Analgesic activity was assessed in male mice (25-35 g) using standard methods...

In the past decades, many studies have shown that tannins (polyphenolic compounds) are involved in defence mechanisms of plants against attack by bacteria, fungi, and herbivores. Little is known about the mechanisms of action of the polyphenolic compounds (Zucker 1983, Scalbert 1991) even though modern analytical methods have improved the analysis of these complex structures (Mole and Watermann...

The administration of fructooligosaccharides (FOS) beneficially modulates gastrointestinal functions and may enhance the metabolism of polyphenols. However, different polyphenolic components in the diet may have different influences on the activities of the digestive enzymes and microbiota in the gastrointestinal tract. Therefore, a 4-week study of forty-eight male Wistar rats was conducted to ...

Plant metabonomic analysis is essential for understanding plant systems responses to osmotic stresses. To understand the comprehensive metabolic responses of Salvia miltiorrhiza Bunge (SMB) to continuous and exhaustive water depletion, we characterized the SMB metabonomic variations induced by three different drying processes using the combined NMR and LC-DAD-MS method. NMR results showed that ...

Phytochemical investigation of polyphenolic contents of Podocarpus gracilior Pilger and Ruprechtia polystachya Griseb leaves were resulted in isolation and identification of three and six known polyphenolic compounds respectively. In addition of a new polyphenolic compound isolated for the first time from nature from R. polystachya which is identified as 4`-O-Galloyl-myricetin-3-O-α-L-rhamnopyr...

Chokeberry fruits are highly valued for their high content of polyphenolic compounds. The use of such abiotic stress factors as UV-C radiation, an electromagnetic field, microwave radiation, and ultrasound, at different operation times, caused differentiation in the contents of anthocyanins, phenolic acids, flavonols, and flavan-3-ols. Samples were analyzed for contents of polyphenolics with ul...
