Ipomoea batatas L. (Lam.) known as "sweet potato" is a plant species of great importance in the human diet due to the contribution of nutrients and also for its bioactive compounds that have various medicinal properties. Its anticancer activity is one of the properties that attract the attention of researchers in the study of plant species. This review aims to make a critical compilation of current information on research that evaluated the antitumor and antiproliferative activity of Ipomoea batatas. The studies included in this review show a diversity of bioactive compounds present in Ipomoea batatas such as phenolic compounds, anthocyanins, flavonoids, coumarins and sterols; also isolated compounds such as pectin, peptides and glycoproteins that can be related to their biological activity. It is concluded that there are positive results about Ipomoea batatas and its anticancer activity evaluated through in vitro and in vivo tests. In humans, safety and efficacy trials are still lacking to support its future use and allow drug development. Further research evaluating the safety and efficacy of reported bioactive compounds in Ipomoea batatas is important for the development of this promising area.

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.

Memory and learning is negatively affected by many factors. Alzheimer{\textquoteright}s disease is a progressive and irreversible neurological disorder that occurs gradually, a sickness that is increasingly common, and multiple scientific articles suggest that essential oils improve memory and learning and are useful in the treatment of various neurodegenerative diseases, including Alzheimer{\textquoteright}s disease. This review aims to conduct a critical collection of current information on research into both memory and learning impairment, as well as essential oils that are able to avoid this neurodegenerative disease. Currently, different animal models have been useful for the study of neurodegenerative problems that alter memory and learning, experimental pharmacological, genetic and toxicological models that can simulate specific cognitive deficit syndromes. In addition, research in this review show several essential oil compounds that present positive results in animal studies, but still lack human clinical trials. Therefore, the assessment of the safety and efficacy of these phytochemical compounds in diseases that cause memory impairment and learning, remain a promising area for future research.

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.
