Five known flavone derivatives were isolated from ethyl acetate fractional extract of the leaves
of Muntingia calabura L. and identified as 8-methoxygalangin (1), kaempferol (2), quercetin (3),
astragalin (4) and isoqercetin (5). Their structures were elucidated by modern spectra including
UV, IR, MS, 1D-NMR, 2D-NMR and by comparison with reported data.
