Limonoids from Australian members of the meliaceae

Abstract

The seeds of Owenia acidula of Owenia venosa were found to contain a simple limonoid and a derivative of the cyclopropane protolimonoid glabretal, which has also been found in the timber of Aglaia ferruginea. The timber of Toona australis was found to contain cedrelone, and the timber seed of Xylocarpus moluccensis (sensu Mabberley) have been found to contain a rich mixture of limonoids. The chemotaxonomic significance of these results is discussed. © 1992.
