Foliar Applications with SUNRED® Biostimulant Advance and Uniform Fruit Ripening in Orange and Olive
2015
This study evaluated the effect of foliar biostimulants on fruit quality of adult 'Valencia' orange and 'Biancolilla' olive trees. Half of the selected orange and olive trees were sprayed twice before harvest with the SUNRED® commercial mix containing phenylalanine, methionine, mono-saccharides and oxylipins from plant extracts as well as potassium salts and urea. Orange and olive yields and fruit quality were measured at harvest, and fruit peel color was determined by digital image analysis. Phenolic and sensory profiles were also determined in the olive oil. In orange, the foliar spray increased TSS:acid ratio and peel color uniformity, while in olive, it increased peel color uniformity, …

La salute delle strutture molli e dure del cavo orale è essenziale non solo per preservare le funzioni ad esse direttamente associate, ma anche per promuovere la salute generale dell’organismo. Tra le problematiche di maggiore interesse clinico a carico della cavità orale ritroviamo: i) le complicazioni post-operatorie che possono verificarsi a seguito di comuni avulsioni dentali che, se non trattate tempestivamente, possono sfociare in gravi parodontiti; ii) i fenomeni di osteonecrosi a carico di mascella e mandibola associate a trattamenti farmacologici nonché alla radioterapia; iii) il carcinoma orale a cellule squamose (OSCC) che è tra i più aggressivi tumori del collo e della testa, ca…

What olive oil for healthy ageing
2015
The olive tree originated in Asia Minor around 6000 years ago and then spread to all the Mediterranean basin. Olive oil is extracted from the pulp of its fruits [1–3]. Many studies show that the nutritional pattern of the so-called Mediterranean Diet is associated with a lower incidence of age-related diseases related to inflammation and oxidative stress, such as cardiovascular disease, Parkinson's disease, Alzheimer's disease and cancer [4–7]. It is now clear that olive oil, as a main source of fat, must play a key role in explaining the health benefits of the Mediterranean Diet.
Over-evaluation of total flavonoids in grape skin extracts containing sulphur dioxide
2015
Abstract Sulphur dioxide (SO 2 ) proved to increase absorbance at 280 nm of grape skin and seed extracts containing it, diluted with ethanol–HCl to assess total flavonoids and anthocyanins in the same analysis. Additional absorbance at 280 nm was also observed in acetone:H 2 O extracts, if the acetone had not completely evaporated before the extracts were diluted with a solvent. Flavonoids were correctly quantified in the extracts when SO 2 or acetone were removed by solid-phase extraction with a C 18 RP as sorbent and methanol as eluting solvent.
HPLC-DAD-ESI-MS2analytical profile of extracts obtained from purple sweet potato after green ultrasound-assisted extraction
2016
International audience; Ultrasound pre-treatment (UAE) was applied to assist the extraction of valuable compounds (polyphenols (especially anthocyanins), and proteins) from purple sweet potato (PSP). Under optimum conditions (ultrasound time (40 min); supplementary hot extraction (80 °C) up to 120 min; pH: 2.5; ethanol concentration: 58%), the highest concentrations of polyphenols (3.877 mg/g), anthocyanins (0.293 mg/g), and proteins (0.753 mg/g) were found, with minimal specific energy consumption (8406 J/mg).Moreover, anthocyanin and non-anthocyanin polyphenols in PSP extract from optimized extraction temperature were identified using HPLC-DAD-ESI-MS2. The major identified anthocyanins we…
