Sign in to saveAlso known as (E)-5-(4-hydroxy-3-methoxystyryl)benzene-1,3-diol, 5-[(E)-2-(4-hydroxy-3-methoxyphenyl)ethenyl]benzene-1,3-diol, isorhapotogenin, 3,4',5-trihydroxy-3'-methoxystilbene
Isorhapontigenin is a tetrahydroxylated stilbenoid with a methoxy group. It is an isomer of rhapontigenin and an analog of resveratrol. It is found in the Chinese herb Gnetum cleistostachyum, in Gnetum parvifolium and in the seeds of the palm Aiphanes aculeata.

Isorhapontigenin is a tetrahydroxylated stilbenoid with a methoxy group. It is an isomer of rhapontigenin and an analog of resveratrol. It is found in the Chinese herb Gnetum cleistostachyum, in Gnetum parvifolium and in the seeds of the palm Aiphanes aculeata.
An isorhapontigenin tetramer, gnetuhainin R, can be isolated from the lianas of Gnetum hainanense.
