Abstract
2D DOSY ^1^H NMR has proved to be a useful technique in the identification of the molecular skeleton of the four major compounds of ethyl acetate extract of aerial parts of Bidens sulphurea (Asteraceae). The combination of this technique with HPLC, mass spectrometry and other NMR techniques enabled the identification of four flavonoid glycosides: quercetin‐3‐O‐β‐D‐galactopyranoside, quercetin‐3‐O‐β‐D‐glycopyranoside, quercetin‐3‐O‐α‐L‐arabinofuranoside and quercetin‐3‐O‐β‐D‐rhamnopyranoside.
