Abstract: Moringa oleifera Lam. is a plant that is known for its nutritional value and particularly for its protein quantity and quality. Due to its nutrient constitution, M. oleifera is used in several regions to treat malnutrition, especially in children. Moreover, M. oleifera contains phytochemical compounds that have important biological activities. Several previous studies confirmed that extracts or compounds isolated from M. oleifera have antioxidant, anti-carcinogenic, anti-diabetic, anti-inflammatory and anti-hypertensive properties, as well as the ability to protect against hepatic damage. This review discusses the characteristics and potential benefits of M. oleifera nutrients and phytochemicals.
