Abstract

Investigation of the aerial parts of Ouratea sulcata led to the isolation of a biflavonoid named sulcatone A, together with the known compounds, 3-hydroxy-2,3-dihydroapigenyl-[I-4',O,II-3']-dihydrokaempferol, amentoflavone, lophirone A, agathisflavone, stigmasterol and stigmasteryl-3-O-beta-D-glucopyranoside. The structure of the compound was assigned as apigenyl-[I-4',O,II-3']-dihydrokaempferol, by means of spectroscopic analysis. Sulcatone A and 3-hydroxy-2,3-dihydroapigenyl-[I-4',O,II-3']-dihydrokaempferol exhibited significant in vitro antimicrobial activities against a range of microorganisms.
