Background: Annona cherimola Mill. (A. cherimola) is mainly characterized by its antioxidant and cytoprotective properties due to their content of phenolic compounds. Objective: To evaluate antioxidant and hepatoprotective activity of ethanol extract of leaves from A. cherimola against induced toxicity by paracetamol in rats. Methods: Amount of total phenolics compounds of ethanol extract of A. cherimola Mill. was determined by the Folin-Ciocalteu method and antioxidant activity was evaluated by DPPH method. Three doses of the ethanol extract of leaves of A. cherimola (250, 500 and 750 mg/Kg/day) were administered to rats and it was evaluated biochemical blood parameters: aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP) were measured, liver tissue was removed for histopathological analysis. Results: Ethanol extract of leaves from A. cherimola had 41.26 mg GAE/g extract and antioxidant DPPH Scavenging Activity had 85.51\%. A. cherimola reduced blood levels of ALT, AST and ALP, compared to control group Paracetamol, ethanol extract, being more effective at doses of 750 mg/Kg/day. Histopathological evaluation suggested that A. cherimola decreased hepatic necrosis and degenerative process induced by paracetamol. Conclusions: Hepatoprotective activity of ethanol extract of leaves of A. cherimola was demonstrated, being hepatoprotective activity dose dependent and the mechanism may involve antioxidant activity and total polyphenols found in extract of this plant.

Background: Ipomoea batatas (L.) Lam. (I. batatas) is a root native from South America that is characterized by its antioxidant, antimicrobial and anti-inflammatory properties. These properties contribute to the wound healing process. Objective: To evaluate the healing activity of a gel based on I. batatas on dermal wound healing in mice. Material and methods: An acid ethanolic extract (1.5 N hydrochloric acid: Ethanol 96 {\textdegree} 15:85, v / v) was prepared with the peels of the roots of I. batatas "purple sweet potato", which was incorporated into the formulations 0.5\% and 1\% gel. Mus musculus Balb / c with induced injury were distributed in four experimental groups: Group I (Control), which did not receive any treatment. Group II (Gel base), Group III (Gel I. batatas 0.5\%) and Group IV (Gel I. batatas 1\%) received the daily administration of topical treatments for 14 days. Wound closure was determined during the experimentation time, then they were euthanized with sodium pentobarbital 60 mg / kg / pc v.ip. to obtain skin samples for histopathological analysis. Results: Group IV shows a higher percentage of wound closure, which is also evidenced in histopathological changes. Conclusions: The 1\% gel based on the ethanolic extract of the peels of the roots of Ipomoea batatas (L.) Lam. they show healing activity in wounds induced in mice, being the most effective treatment.

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.
