Fund Project: The authors are indebted to the Ministry of Health for finacial support and the National Research Center for Analysis of Drugs and Metabolites for the recording of ¹H-NMR and Mass Spectra.

2-p-Anisyl-4-methoxy-5-hydroxybenzofuran was synthesized via intramolecular Wittig reaction between the phosphonium salt and the ester in the presence of triethylamine.Its ¹H-NMR was very similar to that of Gnetifolin A.Thus the revised structure of Gnetifolin A can be considered to be strongly confirmed.
