Moringa peregrina is one of the species of the genus Moringa and is the only genus in Moringaceae family with small dark leaves of flowering plant. It is used in treatment of infectious diseases, inflammation, gastrointestinal, hematological, cardiovascular and hepatorenal disorders. In recent studies anti-fat-like effect of this plant has also been focused by researchers. The aim of this article is to investigate phytochemical properties of Moringa peregrina. So, the plant was prepared by the specified code from Isfahan Center for Research of Agricultural Science and Natural Resources. After getting the required approvals, anthraquinone, saponins, tannins, phenolic groups, flavonols, flavonoids, alkaloids, and cardiac glycosides were tested. Experiments showed that the plant contained alkaloid, tannin, glycoside, flavonoid, flavonol, and phenolic compounds but no antraquinone or saponnin. Based on the results of this research, it is obvious that ethanolic extract of M. peregrina has noticeable antioxidant ability against various oxidative systems. Furthermore, this extract can be used as an accessible source of natural antioxidants in food supplements or in pharmaceutical industries.
