Current study investigated to clarify the potential hypoglycemic effect of adding dry lemon Citrus limon peel, Sidr Ziziphus spina christi leaves and their mixture on rats with hyperglycemia and to evaluate the quality attributes of cupcakes enriched with lemon peel, sidr leaves and their mixture. A total of thirty five (35) male albino rats; Sprague-Dawley Strain were used; the rats were divided into two main groups, (1) the negative control (first group 7 rats), and the second represented diabetic rats (28 rats) which subjected to intraperitoneal injection with Streptozotocin to induce hyperglycemia and then sub divided into 4 groups (each 7 rats) as follows: (2) positive control group fed on standard diet, (3) 5% Sidr Leaves group, (4) 5% lemon peel group and (5) mixture of 5% Lemon peel+ 5 % Sidr leaves group. By the end of study (4weeks) Results showed that, positive control group had the highest levels of blood glucose, glycated hemoglobin, HOMA-IR, serum triglycerides, total cholesterol and MDA compared with negative control. Feeding on lemon peel, Sidr leaves and their mixture had a beneficial effects on blood glucose, glycated hemoglobin, HOMA-IR and lipid profile with elevation of serum total antioxidants and immunoglobin productions and decrements of MDA, diet supplemented with lemon peel, Sidr leaves or their mixture had a protective effects on renal functions as evident by decrements of serum urea and creatinine. Quality attributes of cupcakes enriched with mixture of 5% Lemon peel+ 5 % Sidr leaves; followed by 5% lemon peel showed the higher acceptability score by panelists compared to control sample. The results indicated the potential positive impact of lemon peel and Sidr leaves in controlling negative effects of hyperglycemia.
