Background: There has been an increasing prevalence of metabolic syndrome (MS) caused by life style such as sedentary behavior and western diet. Metabolic syndrome causes degeneration in ren’s structure and processes the elimination of by product in metabolism, which is uric acid. Moringa oleifera Lam. leaves contain antioxidant that can repair damages caused by MS. Studies about improvement of ren’s structure and uric acid level related to Moringa oleifera Lam. leaves’ consumption has not been found yet. Therefore, this study was intended to examine the effects of ethanolic extract in Moringa oleifera Lam. leaves to uric acid and glomerular surface area in male wistar rat (Rattus norvegicus) with induced metabolic syndrome model.Method: This study is an experimental laboratory study. The subjects of this study consisted of 30 rats which were divided into 5 groups with 6 in each group. K1 is control group, K2 is MS group, and K3, K4, and K5 are MS groups given variety of ethanolic extract doses. The induction of MS was done by giving high-fat diet in 28 days and injection of streptozotocin-nicotinamide (STZ-NA) in the 25th day. Rats in group K3, K4, and K5 were given doses of 150, 250, and 350 mg/kgBW in 28 days.Results: The administration of high-fat diet for 28 days and injection of STZ-NA caused MS condition in rats.  Repeated ANOVA and One-Way Anova test showed that the administration of ethanolic extract in Moringa oleifera Lam. leaves with doses of 150, 250, and 350 mg/kgBW in 28 days decreased uric acid significantly (p= 0.001; p=0.001; p= 0.001). Another result also found that ethanolic extract from Moringa oleifera Lam. leaves with doses of 250 and 350 mg/kgBW increased area of glomerular surface area in rats significantly.Conclusion: The administration of ethanolic extract from Moringa oleifera Lam. leaves with doses of 150, 250, and 350 mg/kgBW for 28 days decreased uric acid level in rats. Ethanolic extract of Moringa oleifera Lam. leaves 250 and 350 mg/kgBw doses increase glomerular surface area.Keywords: Moringa Oleifera, uric acid, glomerular cross-sectional area, metabolic syndrome, kidneyCorrespondence: Muhammad Dzaki Darmawan.
