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.
