Effects of Raspberry Fruit (Rubus anatolicus (focke) foke ex hausskn) Hydroalcoholic Extract on Blood Glucose, Lipid Profile and Oxidative Stress Markers in Streptozotocin-diabetic Rats

Background and Objectives: Diabetes is one of the most common endocrine disorders worldwide. Rubus anatolicus is rich in polyphenolic compounds that can protect individual from various chronic diseases such as diabetes. This study was carried out to investigate effects of hydroalcoholic extract of raspberry fruit Rubus anatolicus (focke) on blood glucose levels, lipid profiles and oxidative stress markers in streptozotocin-induced diabetic rats. Materials & Methods: In this study, 32 male Wistar rats weighing 150�200 g were used. Diabetes was induced in rats using streptozotocin and diabetic animals were then treated with raspberry fruit hydroalcoholic extract for 14 days. Rats were anesthetized using xylazine and ketamine mixture and sacrificed. Then, whole blood samples were collected from the animal hearts to assess their serum glucose levels, lipid profiles and oxidative markers. The p-value < 0.05was considered as significant. Results: Results of the present study showed that raspberry fruit extracts significantly decreased serum glucose levels, triglycerides, cholesterol, low-density lipoproteins and malondialdehyde levels in diabetic rats, compared to the diabetic control rats (p < 0.05). Moreover, serum low-density lipoproteins level, total antioxidant capacity and superoxide dismutase activity significantly increased in diabetic rats, compared to diabetic control rats (p < 0.05). Conclusion: The present study showed that fruit extract raspberry included good effects on blood glucose levels, lipid profiles and oxidative stress conditions in diabetic rats. © 2022, National Nutrition and Food Technology Research Institute.
