The anti-ulcer effect of glaziovine, a major psychotropic alkaloid isolated from Ocotea glaziovii (Laureaceae) and belonging to a new chemical class, has been studied in different types of experimentally induced ulcers in the guinea-pig and the rat. The effect of glaziovine was compared with that of
Aporphine, proaporphine and morphinane alkaloids were isolated from the leaves of a Brazilian Lauracea, Ocotea brachybotra (Meiss.) Mez. The known alkaloids were identified through their physico-chemical properties as: (I) (+/-)-glaziovine, (II) dicentrine, (III) ocopodine, (IV) cassynthicine, (V)
