Resveratrol (3,5,4'-Trihydroxy-trans-stilben) ist ein Polyphenol und Phytoalexin, das von mehreren Pflanzen auf natürliche Weise produziert wird, wenn sie durch Krankheitserreger wie Bakterien oder Pilze angegriffen werden. Resveratrol ist derzeit ein Thema zahlreicher tierischer und menschlicher Studien zu seinen Wirkungen. Die Auswirkungen von Resveratrol auf die Lebensdauer vieler Modellorganismen bleiben umstritten, mit ungewisse Auswirkungen bei Fruchtfliegen, Nematodenwürmern und kurzlebigen Fischen. Bei Maus- und Rattenversuche wurden gegen Krebs, entzündungshemmende, blutgerichtende und andere vorteilhafte kardiovaskuläre Wirkungen von Resveratrol berichtet. Die meisten dieser Ergebnisse müssen beim Menschen noch repliziert werden. In der einzigen positiven menschlichen Studie waren extrem hohe Dosen (3–5 g) Resveratrol in einer proprietären Formulierung erforderlich, um den Blutzucker signifikant zu senken. Trotz der Mainstream-Presse, die die Anti-Aging-Effekte von Resveratrol behauptet, gibt es kaum eine wissenschaftliche Grundlage für die Anwendung dieser Ansprüche auf Säugetiere (siehe Abschnitt zur Lebensdauer unten).
Resveratrol findet sich in der Haut von roten Trauben und ist ein Bestandteil von Rotwein, aber anscheinend nicht ausreichend [Zitat benötigt], um das französische Paradoxon zu erklären. Resveratrol wurde auch durch chemische Synthese oder biotechnologische Synthese (metabolisch -technische Mikroorganismen) produziert und wird als Ernährungspräparat verkauft, das hauptsächlich aus japanischer Knotweed abgeleitet wurde.

Introduction |
Resveratrol (3,5,4'-trihydroxy-trans-stilbene) is a polyphenol and phytoalexin produced naturally by several plants when under attack by pathogens such as bacteria or fungi. Resveratrol is currently a topic of numerous animal and human studies into its effects. The effects of resveratrol on the lifespan of many model organisms remain controversial, with uncertain effects in fruit flies, nematode worms, and short-lived fish. In mouse and rat experiments, anti-cancer, anti-inflammatory, blood-sugar-lowering and other beneficial cardiovascular effects of resveratrol have been reported. Most of these results have yet to be replicated in humans. In the only positive human trial, extremely high doses (3–5 g) of resveratrol in a proprietary formulation have been necessary to significantly lower blood sugar. Despite mainstream press alleging resveratrol's anti-aging effects, there is little present scientific basis for the application of these claims to mammals (see Life-Extension section below). Resveratrol is found in the skin of red grapes and is a constituent of red wine, but apparently not in sufficient[citation needed] amounts to explain the French Paradox. Resveratrol has also been produced by chemical synthesis or by biotechnological synthesis (metabolic engineered microorganisms) and is sold as a nutritional supplement derived primarily from Japanese knotweed. |

Function |
1.Resveratrol has the function of antipyretic and analgesic effect. 2.Resveratrol is effective on anti-cancer, anti-mutagenic capacity. 3.Resveratrol can prevent heart and liver damage. 4.Resveratrol is helpful to antithrombotic. 5.Resveratrol can be used to enhance immune system activity in the wound treatment. 6.Resveratrol is natural antioxidant ,and impacts on the metabolism of osseous issue. |
