Allophylus edulis is used in folk medicine primarily for liver conditions such as hepatitis, liver cancer and liver cirrhosis. In vitro hepatoprotective activity was previously demonstrated. The aim of this work was to evaluate the antioxidant capacity and hepatoprotective effect of the ethanolic extract of A. edulis in mice. This was done by first determining the acute toxicity of the extract, evaluating the general behavior, and subsequently verifying the effect on paracetamol-induced toxic hepatitis in male mice. Additionally, the phytochemical profile was performed, and the content of total phenols and its total antioxidant capacity were quantified through the 2,2, azinobis-(3-ethylbenzothiazoline)-6 sulfonic acid radical cation (ABTS) method. The extract of A. edulis leaves did not demonstrate adverse effects up to 2000 mg/kg, p.o. Anthraquinones, flavonoids, triterpenoids, and tannins were detected. A high content of total phenolic compounds (TPC) was related to a high antioxidant capacity. Regarding the results of the biological tests, A. edulis did not affect the general behavior of the mice, and all doses tested decreased glutamic-oxaloacetic transaminase (GOT) and glutamic-pyruvic transaminase (GPT) activity, the main liver enzyme markers of hepatocellular damage. It is concluded that A. edulis has hepatoprotective activity, which could be related to its antioxidant activity.

Diabetes is a serious chronic pathology, with long-term effects including damage to blood vessels or diabetic dyslipidemia. Diabetic dyslipidemia is characterized by increasing concentrations of low-density triglycerides and lipoproteins and a decrease in high-density lipoproteins HDL-cholesterol (HDL-c). This study aimed to evaluate the effect of Prosopis ruscifolia on lipid profile in albino Swiss mice with hyperglycemia and hyperlipidemia. Hyperglycemia was induced by alloxan and the animals were orally treated with Pr (50, 100, and 200 mg/kg) for 45 days. Hyperlipidemia was induced with tyloxapol and the animals were treated with Pr (50, 100, and 200 mg/kg). In hyperglycemic animals treated with 100 mg/kg, there was a decrease in the concentration of cholesterol, a decrease in the concentration of triglycerides, and an increase in HDL-c at the end of treatment compared to untreated hyperglycemic animals. In mice with hyperlipidemia treated with 50 and 100 mg/kg of Pr, serum cholesterol and triglyceride concentration were reduced. HDL-c increased in animals treated with Pr 50, 100, and 200 mg/kg compared to untreated animals. It was observed that the administration of P. ruscifolia in hyperglycemic and hyperlipidemic animals had a favorable effect on the lipid profile.
