Chemical compound
Kobophenol A is a stilbenoid. It is a tetramer of resveratrol. It can be isolated from Caragana chamlagu,[1] from Caragana sinica[2] and from Carex folliculata seeds.[3]
The molecule shows a 2,3,4,5-tetraaryltetrahydrofuran skeleton.[3]
It has been shown to inhibit acetylcholinesterase.[1]
Acid-catalyzed epimerization of kobophenol A to carasinol B can be performed in vitro.[4]
