Objective: Determine the content of total phenols and evaluate the gastroprotective effect of the extract of Persea caerulea (Ruiz \& Pav.) Mez. in mice with induced gastric ulcer. Material and Methods: The bark of Persea caerulea was macerated in 70\% ethanol and the phenol content was determined using the Folin-Ciocalteu method. The female Mus musculus Balb/c specimens were distributed in the following groups: White Control Group, without indomethacin dosing; Negative Control Group, dosing with indomethacin; Positive Control Group treated with ranitidine at a dose of 50 mg/kg; Groups P. caerulea treated with extract at doses of 50 mg/kg, 100 mg/kg and 200 mg/kg. Gastric ulcer was induced with indomethacin orally at a dose of 50 mg/kg, the procedure was repeated 12 hours later; Gastroprotective treatment was administered 60 minutes after each dose of indomethacin, 6 hours after the last dose, sodium pentobarbital was euthanized and the stomach was resected to determine ulceration using the Marhuenda Scale. Results: Higher percentages of gastric ulcer inhibition were obtained in the P. caerulea 100 mg/kg (80\%) and P. caerulea 200 mg/kg (85.71\%) groups. Conclusions: Extract of Persea caerulea (Ruiz \& Pav.) Mez., At doses of 100 and 200 mg/kg of body weight, has a gastric antiulcerative effect which is related to its content of total polyphenols.

Background: Solanum tuberosum L. is an Andean tuber that is mainly characterized by its antioxidant properties. Objective: To evaluate the healing activity of an S. tuberosum-based ointment on wounds induced in mice. Material and methods: Ethanolic extracts of peel and pulp of tubers of S. tuberosum "Tumbay yellow potato" were prepared, which were incorporated into 1\% and 2\% ointment formulations. Mus musculus Balb/c with induced wound were distributed in the following working groups: Group I (Negative Control), Group II (Positive Control: Neomycin, Polymyxin B and Bacitracin Ointment) and Groups III and IV (Ointment at 1 \% and 2\% of S. tuberosum extract, respectively), daily administration of topical treatments were carried out for 07 days. Wound closure was determined during the experimentation time, then euthanized with sodium pentobarbital 60 mg/kg b.w. (i.p.) to obtain skin samples for histopathological analysis. Results: Groups III and IV showed that better evidence of wound closure and scarring in the histopathological analysis, the greatest effect being in Group IV. Conclusions: S. tuberosum ointments show healing activity in induced wounds in mice, the most effective treatment being the 2\% ointment formulation.
