Novel antioxidant compounds from tart cherries (Prunus cerasus).
As indicated by an Fe(II)-induced liposome peroxidation bioassay, the EtOAc extract of tart cherries (Prunus cerasus) was found to have strong antioxidant activity. Purification of this extract afforded chlorogenic acid methyl ester (1) and three novel compounds, 2-hydroxy-3-(o-hydroxyphenyl) propanoic acid (2); 1-(3', 4'-dihydroxycinnamoyl)-cyclopenta-2,5-diol (3), and 1-(3', 4'-dihydroxycinna...
متن کاملAntioxidant Properties of Sweet Cherries(Prunus avium L.) - Role of Phenolic Compounds
Sweet cherries (Prunus avium L.) contain various phenolic compounds which contribute to total antioxidant activity. Total polyphenols, tannins, flavonoids and anthocyanins, and antioxidant capacity in a fruits of a number of selected sweet cherry genotypes were investigated. Total polyphenols content ranged from 4.12 to 8.34 mg gallic acid equivantents/g dry fruit weight and total tannins conte...
متن کاملDetection and quantification of the antioxidant melatonin in Montmorency and Balaton tart cherries (Prunus cerasus).
The antioxidant melatonin was recently identified in a variety of edible plants and seeds in high concentrations. In plants, as in animals, melatonin is believed to function as a free radical scavenger and possibly in photoperiodism. In this study, melatonin was detected and quantified in fresh-frozen Balaton and Montmorency tart cherries (Prunus cerasus) using high-performance liquid chromatog...
متن کاملFoliar Applications of Urea Affect Nitrogen Reserves and Cold Acclimation of Sweet Cherries (Prunus avium L.) on Dwarfing Rootstocks
Seasonal uptake, storage, and remobilization of nitrogen (N) are of critical importance for plant growth. The use of N reserves for new growth in the spring is especially important for sweet cherry (Prunus avium L.), for which new shoot and fruit growth is concomitant and fruit development occurs during a relatively short bloom-toripening period. Sweet cherries grafted on precocious, dwarfing r...
متن کاملDataset on antioxidant metabolites and enzymes activities of freshly harvested sweet cherries (Prunus avium L.) of Campania accessions
In this article, we reported the original data obtained by the study of metabolites and enzymes involved in sweet cherry antioxidant system. We measured hydrogen peroxide (H2O2) and malondialdehyde (MDA), which are indicator of oxidative stress. Moreover, we measured the concentration of reduced and oxidized ascorbate and glutathione that are involved in ROS detoxification together with phenoli...
