El resveratrol (3,5,4'-trihidroxi-trans-stilbene) es un polifenol y fitoalexina producido naturalmente por varias plantas cuando están atacados por patógenos como bacterias o hongos. El resveratrol es actualmente un tema de numerosos estudios animales y humanos sobre sus efectos. Los efectos del resveratrol en la vida útil de muchos organismos modelo siguen siendo controvertidos, con efectos inciertos en moscas de la fruta, gusanos nematodos y peces de corta duración. En experimentos de ratones y ratas, se han informado de los efectos cardiovasculares beneficiosos del resveratrol, antiinflamatorios, de azúcar en sangre y otros efectos cardiovasculares beneficiosos del resveratrol. La mayoría de estos resultados aún no se han replicado en humanos. En el único ensayo humano positivo, las dosis extremadamente altas (3–5 g) de resveratrol en una formulación patentada han sido necesarias para reducir significativamente el azúcar en la sangre. A pesar de que la prensa convencional alega los efectos antienvejecimiento del resveratrol, existe poca base científica presente para la aplicación de estas afirmaciones a los mamíferos (ver la sección de extensión de vida a continuación).
El resveratrol se encuentra en la piel de las uvas rojas y es un constituyente del vino tinto, pero aparentemente no en suficiente [cita necesaria] equivale a explicar la paradoja francesa. El resveratrol también se ha producido por síntesis química o por síntesis biotecnológica (microorganismos de ingeniería metabólica) y se vende como un suplemento nutricional derivado principalmente de nudos japoneses.

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. |
