[Studies on the structure of gnetifolin A of Gnetum parvifolium (Warb.) C.Y. Cheng].
A new component, gnetifolin A, was isolated from the ethyl acetate fraction of the stem of Gnetum parvifolium (Warb.) C.Y. Cheng together with three known components isorhapontigenin, resveratrol and beta-sitosterol. The structure of gnetifolin A has been established as 2-(3',5'-dihydroxy-4'-methoxyphenyl)-3-methoxy-5-hydroxybenzofuran by spectroscopic methods (UV, IR, MS, 1HNMR, 13CNMR, 2D-NMR).
