Moringa leaves are known as herbs that have many properties. The study aimed to analyzed moringa leaf extract against tissue histology, serum protein levels, fetal conditions at birth from distended mice with malnutrition. The research design was a pretest post test control group design using 28 distended mice with malnutrition, divided into 7 groups with 4 mice - Group. In the treatment group given moringa leaf extract with a dose of 720; 850 and 1000 mg/day during pregnancy 19-21 days. We found the condition of malnutrition causes hepar tissue histology to deteriorate due to increased hepar cell death which affects decreased protein synthesis, but does not affect renal tissue histology. The administration of moringa leaf extract does not have an effect on the distending of malnutrition conditions both the results of histology of hepar tissue and kidneys, serum protein levels and fetal conditions at birth, but in distending without malnutrition (negative control) provides the best results of tissue histology, serum protein levels and provides the highest fetal weight and length compared to other groups.
