The total of fourteen known compounds was isolated from the fruits, leaf and stem of Fadogia homblei De Wild. (Rubiaceae) and identified as: a coumarin, 7-hydroxy-6-methoxy-2H-1-benzopyran-2-one (scopoletin) 1, two flavones; 3′,4′,5,7-tetrahydroxyflavone (luteolin) 2 and quercetin-3-O-β-D-galactoside 3, four lupane triterpenoids; lupeol 4, betulinic acid 5, 3β-dodecanoyllup-20(29)-en-28-al 6, lup-20(29)-en-3β-ylhexadecanoate 7, and two steroids; sitosterol 8, stigmasterol 9, a lignan 4,4′-dihydroxy-3,3′-dimethoxy-7,9′:7′,9-diepoxylignan ((-)-pinoresinol) 10, a phaeophytin A 11, an uracil 12, an oleanolic acid 13, and an ursolic acid 14. To our best knowledge, this is the first report for isolation of these compounds from this species. This finding is nevertheless significant as it is the first report of uracil from a plant source other than from various species of ferns.
