Enzyme activity and biochemical changes of three date palm cultivars with different softening pattern during ripening

The physicochemical composition changes during palm ripening were studied. The activities of invertase and cell wall-modifying enzymes, namely pectin methylesterase (PME), β-galactosidase (β-Gal), endo-1,4-β-d-glucanase (EGase), and cellulase were monitored during growth and ripening of Shahani, Piaro and Deiry cultivars with different texture. Also we estimated the concentrations of six organic acids by HPLC .Reducing sugars, […]

Evidence for the involvement of the monoaminergic system, but not the opioid system in the antidepressant-like activity of ellagic acid in mice

Dietary flavonoids possess a multiplicity of neuroprotective actions in various central nervous pathophysiological conditions including depression. Ellagic acid is a polyphenolic compound that occurs in plants such as raspberries, nuts and eucalyptus species. The present study was designed to investigate the antidepressant-like effect of ellagic acid in mice using forced swimming test (FST) and tail […]
