In the early nineties the presence of flavonoids in Citrus juices began to attract the attention of a number of researchers, as a result of their biological and physiological importance. This short review will explore two different aspects. The first part will focus on analytical techniques for the characterization of juices from different Citrus fruits(More)
Every year tons of pistachio hulls are separated and eliminated, as waste products, from pistachio seeds. In this study the hulls of ripe pistachios were extracted with two organic solvents (ethanol and methanol) and characterized for phenolic composition, antioxidant power and cytoprotective activity. RP-HPLC-DAD-FLU separation enabled us to identify 20(More)
A number of studies have demonstrated that consuming almonds increases satiety but does not result in weight gain, despite their high energy and lipid content. To understand the mechanism of almond digestion, in the present study, we investigated the bioaccessibility of lipids from masticated almonds during in vitro simulated human digestion, and determined(More)
Dihydrochalcones are a class of secondary metabolites, whose demand in biological and pharmacological applications is rapidly growing. Phloretin is one of the best known and abundant dihydrochalcone characterized by the presence of 2,6-dihydroxyacetophenone pharmacophore. It is a versatile molecule with anticancer, antiosteoclastogenic, antifungal,(More)
HPLC separation of flavonoids and furocoumarins in the crude juices of three cultivars of Citrus bergamia Risso ("Castagnaro", "Fantastico", and "Femminello") was carried out on a C18 reversed phase column. The analysis was performed in a single run using a DAD detector coupled with an ESI-MS-MS source. Two furocoumarins (bergapten and bergamottin) were(More)
During our experimental work, aggregation of bovine serum albumin was obtained incubating the protein solution at 60 degrees C to investigate temperature-induced secondary structure, conformation changes and anti-aggregative activity of trehalose. IR-measurements suggested that in the presence of 1.0M of trehalose there is a little increase in short segment(More)
Considering its complex molecular pathophysiology, beta-thalassemia could be a good in vivo model to study some aspects related to erythrocyte functions with potential therapeutic implications not only within the frame of this particular hemoglobinopathy but also with respect to conditions in which the cellular milieu, altered by a deranged anion exchanger,(More)
Resveratrol, an important phytoalexine found in many plants, has been shown to be significantly effective in the treatment of several pathological conditions such as cancer, coronary heart disease and osteoarthritis. This study focuses on the effects of this drug on human red blood cells. In particular, we have examined the influence of resveratrol on Band(More)
The antioxidative activity of some natural flavonoids was analyzed against the stable free radical 2,2-diphenyl-1-picryhydrazyl. The results indicate that the scavenging power of the tested flavonols is higher than that of the synthetic antioxidants butylated hydroxyanisole and butylated hydroxytoluene; instead, the flavanones show little activity, as(More)
In spite of the growing variety of biological applications of dendrimer-based nanocarriers, a major problem of their potential applications in bio-medicine is related to the disruption of lipid bilayers and the cytotoxicity caused by the aggregation processes involved onto cellular membranes. With the aim to study model dendrimer-biomembrane interaction,(More)
