Chemical compound
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]
