The new quercetin 3-[2,3,4-triacetyl-α-L-arabinopyranosyl(1→6)-β-D-galactoside] has been isolated along with 5,7-dihydroxychromone and 5,7-dihydroxychromone 7-β-D-glucoside from fresh flowers of Calluna vulgaris. Structural elucidation of these Natural products was achieved mainly by 1H and 13C NMR.
