Isoflavonoid constituents of the heartwood of Cordyla africana

Abstract

Three further compounds have been isolated from the heartwood of Cordyla africana(Leguminosae), and shown by chemical degradation and spectral considerations to be 6-hydroxy-2′,7-dimethoxy-4′,5′-methylenedioxy-5,6,7-trimethoxy-3′,4′-methylenedioxy-, and 5,6,7,8-tetramethoxy-3′,4′-methylenedioxy-isoflavone. The mass spectra of these, and related isoflavones are discussed.
