Resveratrol is a type of natural polyphenol compound, and a phytoalexin produced by several plants when the plant is under attack by pathogens.

 

Resveratrol is extracted from dried rhizome of reynoutria japonica, which is also known as polygonum cuspidatum or japanese knotweed. Resveratrol is off-white (50%) to white powder (98%), soluble in ethanol (50 mg/mL), DMSO (16 mg/mL),  (50 mg/mL) and other organic solvents, hardly soluble in water (3 mg/100mL).
