Isorhapontigenin
IUPAC 名称
5-[(Z)-2-(4-hydroxy-3-methoxyphenyl)ethenyl]benzene-1,3-diol
描述
Isorhapontigenin is a member of the class of compounds known as stilbenes. Stilbenes are organic compounds containing a 1,2-diphenylethylene moiety. Stilbenes (C6-C2-C6 ) are derived from the common phenylpropene (C6-C3) skeleton building block. The introduction of one or more hydroxyl groups to a phenyl ring lead to stilbenoids. Isorhapontigenin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Isorhapontigenin can be found in garden rhubarb, which makes isorhapontigenin a potential biomarker for the consumption of this food product. 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 .
