Austrotaxus spicata Compton is an uncommon austral Taxaceae native to New Caledonia. The study of its leaves and trunk bark has allowed the isolation of 31 taxanes. Most of them are alkaloids owing to the presence of a dimethylaminophenylpropionic acid side-chain. Contrary to the Taxus species, Austrotaxus has shown the presence of alkaloids in the trunk bark, but no oxetane compounds were found.
