A new flavone from the roots of Milicia excelsa (Moraceae).
A new flavonoid identified as 2-(2,4-dihydroxyphenyl)-5-hydroxy-8,8-dimethyl-4H,8H-pyrano[2,3-f]chromen-4-one (2'-hydroxyatalantoflavone) (1) was obtained from the roots of Milicia excelsa along with five known compounds including atalantoflavone (2), neocyclomorusin (3), 6-geranylnorartocarpetin (4), cudraxanthone I (5), and betulinic acid (6). The structures of the isolates were established on the basis of their spectral data and by comparison with those reported in the literature.
