Maytenus truncata Reiss (Celastraceae) is a native plant from Bahia (Brazil), known as "espinheira-santa". It is popularly used in the form of decoct of leaves (tea) as antiulcerogenic, similarly to Maytenus ilicifolia, the true "espinheira-santa". This study aims to evaluate antiulcerogenic and healing activities, as well as the phytochemical profile, of ethyl acetate and methanol crude extracts of Maytenus truncata. Per os administration of these extracts at 120 mg/kg and 240 mg/kg doses decreased the severity of gastric lesions induced by cold-restraint stress (-18 °C for 45 minutes) in rats, with more significant results for the crude methanol extract. The administration of the extracts caused pH increase. The results obtained with the administration of crude methanol extract are not contrary to its popular use, not only for the activity observed but, also, for its high polarity that enables the obtention of the active principles through infusion, though clinical studies should be performed to confirm this assertion.
