Rhapontigenin is a stilbenoid. It can be isolated from Vitis coignetiae or from Gnetum cleistostachyum.[2]

It shows an action on prostate cancer cells.[3] It has been shown to inhibit the human cytochrome P450 1A1,[4] an enzyme implicated in the biotransformation of a number of carcinogenic and immunotoxic compounds.

Injected in rats, rhapontigenin shows a rapid glucuronidation and a poor bioavailability.[5]
