Abstract

Context: Saraca asoca (Leguminosae) has been widely used in the Ayurvedic system of medicine for various ailments, and it has been used to treat diabetes as a folk medicine.

Aims: To investigate the anti-hyperglycemic and anti-hyperlipidemic effect of ethanolic extracts of S. asoca (EESA) flowers in alloxan-induced diabetic rats.

Methods: The anti-hyperglycemic activity of EESA was evaluated by using normal and alloxan-induced (120 mg/kg, i.p.) diabetic rats. In the sub-chronic animal model of diabetes mellitus, EESA was orally administered to normal and alloxan-induced-diabetic rats at doses of 200 and 400 mg/kg p.o. per day for 28 days.

Results: Fasting blood glucose (FBG), insulin, glycated hemoglobin (HbA1c) levels, lipid profiles, alkaline phosphatase (ALP), and body weights were monitored at the end of 28 days in the EESA treated diabetic rats. The anti-hyperglycemic effect of EESA was more pronounced at the doses of 200 and 400 mg/kg in alloxan-treated diabetic rats as compared with vehicle-treated rats. EESA also showed a significant (p<0.05) increase in serum insulin levels and body weights, while there was a significant reduction in the levels of ALP, HbA1c, serum triglyceride and total cholesterol. EESA also showed a significant anti-hyperlipidemic effect, as evidenced by the increased HDL-c level of alloxan-induced diabetic rats.

Conclusions: The results of the current investigation indicate that EESA possesses a significant anti-hyperglycemic effect and anti-hyperlipidemic effect.

Keywords: alloxan; anti-hyperglycemic; diabetes mellitus; hypolipidemic; oral glucose tolerance test; Saraca asoca.

Resumen

Contexto: Saraca asoca (Leguminosae) se ha utilizado ampliamente en el sistema de medicina ayurvédica para diversas dolencias y para tratar la diabetes como medicina popular.

Objetivos: Investigar el efecto antihiperglucémico y antihiperlipidémico de extractos etanólicos de flores de S. asoca (EESA) en ratas diabéticas inducidas por aloxano.

Métodos: Se evaluó la actividad antihiperglucémica de EESA utilizando ratas diabéticas normales e inducidas por aloxano (120 mg/kg, i.p.). En el modelo animal subcrónico de diabetes mellitus se administró EESA por vía oral a ratas normales y con diabetes inducida por aloxano en dosis de 200 y 400 mg/kg p.o. por día durante 28 días.

Resultados: La glucosa en sangre en ayunas (FBG), la insulina, los niveles de hemoglobina glucosilada (HbA1c), los perfiles de lípidos, la fosfatasa alcalina (ALP) y los pesos corporales se controlaron al final de los 28 días en las ratas diabéticas tratadas con EESA. El efecto antihiperglucémico de EESA fue más pronunciado a las dosis de 200 y 400 mg/kg en ratas diabéticas tratadas con aloxano en comparación con ratas tratadas con vehículo. EESA también mostró un aumento significativo (p<0,05) en los niveles de insulina sérica y el peso corporal, mientras que hubo una reducción significativa en los niveles de ALP, HbA1c, triglicéridos séricos y colesterol total. EESA también mostró un efecto antihiperlipidémico significativo, como lo demuestra el aumento del nivel de HDL-c de ratas diabéticas inducidas por aloxano.

Conclusiones: Los resultados de la investigación actual indican que EESA posee un efecto antihiperglucémico significativo y un efecto antihiperlipidémico.
