RESUMEN

Peptic ulcers (PU) are a breach in the mucosa of the digestive tract and are related to several factors including an altered immune system and an unbalanced diet. Current treatment carries to long-term complications; therefore, the use of medicinal plants is an alternative for several inflammatory diseases including ulcerative lesions. Kalanchoë gastonis-bonnieri, is a succulent plant and, has been used in traditional medicine against gastric ulcers, inflammation, and cancer among others. The main goal of this work was to analyze the anti-ulcerogenic potential of extracts from leaves of K. gastonis-bonnieri in an assay of ethanol-induced gastric ulcers. An ethanolic extract was obtained by maceration from fresh leaves of K. gastonis-bonnieri, and fractions were obtained through bipartition and chemical fractioning. The chemical characterization of the extract was made through HPLC, GC-MS, and NMR. Total extract and fractions showed an anti-ulcerogenic effect in specimens of male ICR mice with a gastric ulcer index (UI) of 3.27-5.47. The recorded effect is attributed to the presence of terpenoid compounds such as ß-Amyrin acetate, which showed antioxidant properties and lessened formations of ulcers induced by ethanol administration in mice stomach.
