Two novel prenylated flavones, 2,4,3'-trihydroxy-7,2'-dimethoxy-6-(2-methylbut-1-enoxy)flavone and 2,4,7,3'-tetrahydroxy-6,2'-dimethoxy-5-(2-methylbut-1-enyl)flavone have been isolated from the aerial parts of Melicope micrococca (Rutaceae) together with the known compounds, quercetin 3-O-β-D-glucopyranoside, isorhamnetin 3-O-rutinoside, the acridone alkaloid arborinine, sitosterol 3β-O-glucopyranoside (daucosterol) and 4-O-methyl-myo-inositol (sequoyitol). The structures of all compounds were elucidated by spectroscopic methods.
