Phenolic compounds were extracted from European and Japanese grapevine species (Vitis vinifera and V. coignetiae) seeds using 80% methanol or 80% acetone. The total content of phenolic compounds was determined utilizing Folin-Ciocalteu's phenol reagent, while the content of tannins was assayed by the vanillin and BSA precipitation methods. Additionally, the DPPH free radical and ABTS cation rad...

The antioxidant capacity and total phenolic content of seeds of three types of pitaya namely Hylocereus polyrhizus, Hylocereus undatus and Selenicereus megalanthus and the fatty acid content of pitaya seeds oil were examined in this study. The ethanolic extracts of H. polyrhizus seeds showed significantly high (p<0.05) total phenolic (43.9 mg GAE/100g dry weight) and flavonoid (50.8 mg CAE /100...

Among the Sicilian economic productive sectors, that of wine production has today a considerable value. However, with growth this sector, notable was increase in waste, which to date is not only an damage for companies, but also threat environment. It known waste from properties (e.g., antioxidants) have potential reuse at cosmetic, pharmaceutical and nutritional levels obtain economically sust...

Ionizing radiation (IR) has become an integral part of the modern medicine--both for diagnosis as well as therapy. However, normal tissues or even distant cells also suffer IR-induced free radical insult. It may be more damaging in longer term than direct radiation exposure. Antioxidants provide protection against IR-induced damage. Grapes are the richest source of antioxidants. Here, we assess...
