Kobophenol A is a stilbenoid and 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.
