Abstract: Moringa oleifera, belonging to the Moringaceae family, is a biennial deciduous tree that is distributed in
tropical and sub-tropical regions of Africa and Asia. The plant has been introduced into China and planted in Guangdong,
Yunnan and Taiwan provinces. Moringa oleifera is called as “Miracle Tree” due to its rapid growth. Both its leaves and
tender fruits are edible. Moringa oleifera seeds contain more than 30% oil. Moringa oleifera seed proteins are traditionally
utilized for water purification owing to advantages such as natural occurrence, no toxic or side effects and easy degradation.
Furthermore, Moringa oleifera contains carbamate derivatives and phenolic compounds, which show a diversity of
biological activities including antifungal, anti-hypertensive, anti-diabetic effects. This paper reviews the chemical
constituents and biological activities of Moringa oleifera with focus on safety evaluation and chemical analysis of Moringa
oleifera for the purpose of providing evidence for the development and utilization of Moringa oleifera.

Key words: Moringa oleifera, chemical constituents, biological activities, safety evaluation, constituents analysis
