Pomegranate peel is a natural source of phenolics, claimed to possess healing properties, among which are antioxidant and antidiabetic. In the present study, an ethyl acetate extract, obtained by Soxhlet from the peel of Dente di Cavallo DC2 pomegranate (PGE) and characterized to contain 4% w/w of ellagic acid, has been evaluated for its hypoglycemic, antiglycation, and antioxidative cytoprotective properties, in order to provide possible evidence for future nutraceutical applications.

DR2B and DR2C extracts, obtained by ethanolic maceration of peel from commercially
and physiologically ripe aubergine berries, were studied for the antioxidative cytoprotective
properties and anti-HSV-1 activity, in line with the evidence that several antioxidants can impair
viral replication by maintaining reducing conditions in host cells. The antioxidative cytoprotective
effects against tBOOH-induced damage were assessed in Caco2 cells, while antiviral activity was

A hydroalcoholic extract from female inflorescences of Humulus lupulus L. (HOP extract) was evaluated for its anti-influenza activity. The ability of the extract to interfere with different phases of viral replication was assessed, as well as its effect on the intracellular redox state, being unbalanced versus the oxidative state in infected cells. The radical scavenging power, inhibition of lipoperoxidation, and ferric reducing activity were assayed as antioxidant mechanisms. A phytochemical characterization of the extract was also performed.

Fully ripe fruits and mature leaves of Elaeagnus angustifolia were harvested and analyzed by means of analytical and biological tests to better comprehend the chemical composition and therapeutic/nutraceutical potential of this plant. Fruits and leaves were dried and the obtained powders were analyzed to study their color character and (via headspace gas chromatography) describe the chemical profile.

Objective: The aim of the present study was to investigate how different Extravirgin Olive Oils (EVOOs), obtained by blending Olea europea cultivars, could influence the cell growth, the response to inflammatory stimuli and oxidative stress in a culture of osteosarcoma cell line, Saos-2.
