Abstract
Four new phenylphenalenone pigments have been isolated from Anigozanthos rufus Labill. and their structures have been determined. The known compound 2-phenylnaphthalic anhydride was also isolated from the plant. The synthesis of one of the new pigments, and of some related compounds, is described.
