In the course of our studies of Spanish Papaveraceae, two novel highly coloured, weakly basic alkaloids have been isolated from Glaucium Flavum Cr. var. Vestitum. They are present in only very small amounts, along with small quantities of the closely related yellow alkaloid (IV) (1) and colourless alkaloids, and large amounts of Glaucine (I) (1). We have named them Corunnine and Pontevedrine and propose structures (II) and (III), respectively, on the following evidence. To our knowledge, Pontevedrine (III) represents the fmt example of a 5,7dioxo_aporphine (2).
