Dry latex of Paaver orientale was shown to contain 20% oripavine and 9% thebaine. Dry latex of Papaver pseudo-orientale contained two major alkaloids, isothebaine (11.7%) and orientalidine (0.5%), and the minor alkaloids bracteolin, salutaridine, Or1, Or2, PO-4, alborine (PO-5), and a novel alkaloid
