been extracted. Although their structures are related to many Amaryllidaceae alkaloids, the compounds show no basic properties since the nitrogen is amidic in character. The first substance, named narciclasine, shows a strong antimitotic activity and has been assigned structure VIII or its mirror image. The second compound, named narciprimine, has no antimitotic activity and has been given structure XII
