Kobophenol A

Kobophenol A is a stilbenoid. It is a tetramer of resveratrol. It can be isolated from "Caragana chamlagu", from "Caragana sinica" and from "Carex folliculata" seeds.
The molecule shows a 2,3,4,5-tetraaryltetrahydrofuran skeleton.
It has been shown to inhibit acetylcholinesterase.
Acid-catalyzed epimerization of kobophenol A to carasinol B can be performed in vitro.
