    ABSTRACT

    Objective: This study aimed to evaluate the antihyperglycemic properties of the ethanol extract, subsequent fractions, and farnesol obtained from the leaves of Annona diversifolia on alloxan‑induced diabetic and normal mice. Materials and Methods: Bioassay‑guided fractionation of the ethanol extract of the leaves of A. diversifolia (EELAd) was performed on alloxan‑induced Type 2 diabetic and normoglycemic (NM) mice. Oral glucose tolerance test (OGTT), oral sucrose tolerance test (OSTT), and oral lactose tolerance test (OLTT) were performed in fast NM mice (FNM). Results: The EELAd, CHCl3 fraction, and farnesol induced a significant reduction of postprandial hyperglycemia in acute and subchronic tests using AITD mice. When EELAd, CHCl3 fraction, and farnesol were tested on NM in subchronic assays, these did not affect glycemic levels. In the case of acute test on NM, only CHCl3 fraction induced a hypoglycemic effect at 2 h after the treatment. OLTT and OSTT showed that the EELAd, CHCl3 fraction, and farnesol induced a significant reduction of hyperglycemia levels in FNM at 2 h after a lactose or sucrose load comparable to acarbose. In the case of OGTT was observed a significant reduction of hyperglycemia levels in FNM mice at 2 h after a glucose load comparable to canagliflozin. Conclusion: The EELAd and farnesol induced a significant reduction of postprandial hyperglycemia on AITD mice in acute and subchronic assays. Our results suggest that the control of postprandial hyperglycemia may be mediated by the regulation of absorption of glucose and inhibition of disaccharide digestion such as sucrose and lactose. Finally, the results explained the use of A. diversifolia in Mexican traditional medicine as an antihyperglycemic agent.
