Antidiabetic and Antioxidant Effect Combination Vasconcellea pubescens A.DC. and Momordica charantia L. Extract in Alloxan- Induced Diabetic Rats

Introduction: Mountain papaya (Vasconcellea pubescens A.DC.) and bitter melon (Momordica charantia L.) fruit extract have total flavonoids and some metabolite from its contains. The use of a single dose in the treatment of diabetes is often considered to lack a strong effect. Giving a combination of the compound is a solution to provide a synergistic effect in treatment. Material and Methods: Rat were divided into eight groups (normal, negative control, glibenclamide as a positive control, and five dose extract group). The single dose mountain papaya extract (MPE) and bitter melon extract (BME) were given at 174 mg/kg b.w of MPE, and 380 mg/kg b.w of BME in oral administration. Combination of MPE:BME (25:75, 50:50, 75:25)% or (87:190; 44:285 and 130:95) mg/kg b.w in oral administration. Induction of diabetes used alloxan dose of 150 mg/kg b.w intraperitoneally. The treatment was performed for 21 days with a frequency of once a day. Blood sugar level was measured at pretest, 7^th, 14^th, and 21^st days. At the end of the test, measurements of malondialdehyde (MDA), glutathione (GSH), and pancreatic morphology were measured. Data were analyzed by ANOVA statistic. Results: The single and combination of MPE-BME showed an decrease in blood glucose levels significantly compared with the negative control (p ≤ 0.05). The same results from measurements of levels of malondialdehyde (MDA), glutathione (GSH), and pancreatic morphology. Conclusions: Based on the research, a combination of the MPE-BME had antidiabetic and antioxidant activity, but the activity was not significantly different from both single-dose extract (p> 0.05).
