| Abstract: | The whole plants of four Wurmbea species and one Burchardia species were analysed. All Wurmbea species contained tropolone alkaloids, mainly colchicine, 2-demethylcolchicine, 3-demethylcolchicine and β-lumicolchicine. From all these species the flavone luteolin and 2-hydroxy-6-methoxybenzoic, vanillic and salicylic acids were isolated. Burchardia multiflora yielded one unidentified non-tropolone alkaloid, luteolin, and benzoic and salicylic acids. The chemotaxonomic significance of the substances isolated within the subfamily Wurmbaeoideae is discussed. |
