This study aims to determine the effect of the effect of ekor naga leaves extract which has potentian as an antioxidant on malondialdehyde levels as a prooxidant marker in alloxan-induced diabetes mellitus rats. The reseaech method used a post test only control group design. The test animals used were 20 animals, each group of 5 test animals. Group 1: Positive Control (Glibenclamide 10 mg/Kg BW), Group 2: Negative Control (Na CMC 0,5%), Group 3: Ekor Naga Leaf Extract 250 mg/Kg BW, and Group 4: Ekor Naga Leaves Extract 500 mg/Kg BW.

Followed by a dose of 250 mg/Kg BW with malondialdehyde value of 2,144 nmol/mL.
