Isorhapontigenin is a tetrahydroxylated stilbenoid with a methoxy group. It is an isomer of rhapontigenin and an analog of resveratrol.[1] It is found in the Chinese herb Gnetum cleistostachyum,[2] in Gnetum parvifolium[3] and in the seeds of the palm Aiphanes aculeata.[4]
An isorhapontigenin tetramer, gnetuhainin R, can be isolated from the lianas of Gnetum hainanense.[5]
Isorhapontin, the isorhapontigenin glucoside, can be found in spruce species such as the Norway spruce (Picea abies), the sitka spruce (Picea sitchensis) and the white spruce (Picea glauca).[6]
