Eleven homoeqthrina-type alkaloids (l-9, 11, 12) have been isolated from A. cqressoides (Taxodiaceae), of which six (Cj-2; &%!)-2had not previously been reported.The genus Athrotaxis is confined to Tasmania, and comprises the only representatives in the southern hemisphere of the Taxodiaceae, a rather small family that nevertheless contains some of the largest and tallest trees in the world: Sequoiadendron gigantewn (Big Tree) and Sequoia sempervirens (Californian Redwood) respectively. The family is now largely confined to eastern Asia and north America, but was once much more widely distributed as shown by fossil specimens, one of which (Metnsequoia g&ptostrobus) was found in recent times still growing in China. Although some species had been found to give alkaloid testsI, no alkaloids have previously been isolated from members of the Taxodiaceae2.A. cupressoides Don (Pencil Pine) is a tree that grows above 1000 m in central and western Tasmania. The present report describes eleven alkaloids which have been isolated from its bark and foliage.
