1. Imperialine, imperialone, peimisine, and the new alkaloids edpetiline, eduardine, edpetilidine, and edpetilidinine have been isolated from the epigeal part of P. eduardi. 2. The hydrolysis of edpetiline has given D-glucose and imperialine. 3. The structural formula of edpetiline has been established by the condensation of imperialine with tetraacetylbromoglucose. © 1966 The Faraday Press, Inc.
