1.Introduction of Resveratrol

Resveratrol (3,5,4'-trihydroxy-trans stilbene) is a stilbenoid, a type of natural phenol, and a phytoalexin

produced naturally by several plants –especially the roots of theJapanese Knotweed, from which it is

extracted commercially – when under attack bypathogens such as bacteria or fungi.
