A new dehydroaporphine alkaloid (-)- 6a, 7-dehydrofloripavidine has been isolated from the aerial parts of Papaver fugax Poir. ( Papaveraceae) collected from Erzurum ( Eastern Anatolia). (-)- Floripavidine ( aporphine) and (-)- mecambrine (proaporphine) were isolated as major alkaloids. Other bases present were (+)-salutaridine (promorphinane) and argentinine ( phenanthrene). The presence of argentinine has been shown for the first time in the Papaveraceae.
