Resveratrol is a natural anti oxidant formed in the stem cells of the grapes and berries. Resveratrol was, firstly, discovered in the roots of Japanese knotweed. It is formed in the response to attack by bacteria or fungi. Resveratrol is the most potent anti inflammatory, anti cancer , and anti aging an agent discovered till date. Resveratrol is found in the skin of red grapes and is a constituent of red wine as well. A total amount of Resveratrol per serving of wine (a 5-ounce glass) for white wines is found to be between 0.01 to 0.27 mg.
It exists as two geometric isomers: cis (Z) and trans (E), with cis-isomer. The trans form can undergo isomerization to the cis form when exposed to ultraviolet irradiation.
Trans form is more stable even in under accelerated conditions of the 75% humidity and 40 degrees C under normal atmospheric pressure. Thus resveratrol is found stable in plants grown in the hotter climates. That entire means is that resveratrol can exist in both forms in a given plant.
The mechanisms of resveratrol’s apparent effects on life extension are not fully understood, but they appear to mimic several of the biochemical effects of calories restriction. A new report indicates that resveratrol activates Sirtuin 1 (SIRT1) and PGC-1a and improves functioning of the mitochondria. Another research calls into question the theory connecting resveratrol, SIRT1, and calorie restriction.
Resveratrol content interferes with all three stages of carcinogenesis” initiation, promotion and progression. Experiments in cell cultures of varied types and isolated sub cellular systems in vitro imply many mechanisms in the pharmacological activity of resveratrol.
Resveratrol content was reported effective against neuronal cell dysfunction and cell death, and in theory could help against diseases such as Huntington’s disease and Alzheimer’s disease. Again, this has not yet been tested in humans for any disease. Resveratrol content is the best for any heart ailment as well.
