Background: Diabetes mellitus treatment is based on oral hypoglycemic agents or insulin. Medicinal plants constitute an option, and the leaves of Prosopis ruscifolia (Pr) were shown to be effective in reducing glycemia in hyperglycemic animals. Objective: In this paper, we report the effect of P. rusciofolia (Pr) on insulin and incretin secretion in alloxan-induced hyperglycemic rats. Methodology: The effective dose was selected, and four groups (n=10) of Wistar rats were used. Two groups with normal glycemia received water or Pr (75 mg/Kg, per os, p.o.), and two groups with hyperglycemia induced by alloxan (intraperitoneal, ip), received water or Pr (75 mg/Kg, p.o.) for 2 weeks. Oral glucose tolerance test, and incretin and insulin levels were measured at the end of the experimental period. Results: The results showed that extract promotes better tolerance to oral glucose overload, in addition to a statistically significant (p<0.001) increase in blood levels of incretin and insulin, compared to the hyperglycemic rats. Conclusion: It is concluded that the ethanolic extract of P. ruscifolia leaves has a hypoglycemic effect in hyperglycemic animals by a mechanism that involves the incretin-insulin system.
