Variability in the Content of Trans-Resveratrol, Trans-ε-Viniferin and R2-Viniferin in Grape Cane of Seven Vitis vinifera L. Varieties during a Three-Year Study.
Grape canes are a waste product from viticulture that show potential as an industrially extractable source of stilbenes, which are valuable for medical and other purposes. In this work, grape canes collected in three consecutive years (2014-2016) at six different places in South Moravia, Czech Republic were extracted, and the contents of trans-resveratrol, trans-ε-viniferin, and r2-viniferin we...
متن کاملEffect of Trans-ε-Viniferin on In Vitro Porcine Oocyte Maturation and Subsequent Developmental Competence in Preimplantation Embryos
Trans-ε-viniferin is a naturally occurring polyphenol belonging to the stilbenoid family that has been isolated from Vitis amurensis, one of the most common wild grapes in Asia. We investigated the effects of trans-ε-viniferin on in vitro maturation (IVM) and developmental competence after in vitro fertilization (IVF) or parthenogenesis (PA). We observed that trans-ε-viniferin treatment during ...
متن کاملThe Differential Effects of Resveratrol and trans-ε-Viniferin on the GABA-Induced Current in GABAA Receptor Subtypes Expressed in Xenopus Laevis Oocytes.
PURPOSE The natural products resveratrol and trans-ε-viniferin have been reported to have many beneficial effects, which include the enhancement of cognition and memory. There have been no studies which have reported the effects of these compounds on the different GABAA receptor subtypes and this study aimed to address this. METHODS The effects of both resveratrol, and its dimer, trans-ε-vini...
متن کاملSurvey of the trans-resveratrol and trans-piceid content of cocoa-containing and chocolate products.
Dietary resveratrol (3,4',5-trihydroxystilbene) has been implicated in the health benefits associated with grapes and red wine, more specifically with potential benefits for metabolic syndrome, energy use, and increased endurance. Levels of trans-resveratrol and its glucoside, trans-piceid, were determined in 19 top selling commercially available cocoa-containing and chocolate products from the...
متن کاملIn Vitro Glucuronidation and Sulfation of ε-Viniferin, a Resveratrol Dimer, in Humans and Rats.
ε-Viniferin is a resveratrol dimer that possesses antioxidant or anti-inflammatory activities. However little is known about the metabolism of this oligostilbene. This study was thus undertaken as a first approach to identify and characterize the metabolites of ε-viniferin and to describe the kinetic profile of their appearance in humans and rats. The glucuronides and sulfates of ε-viniferin we...
