The Moringaceae is a monotype family of sole genus Moringa
with 10 to 12 species in tropical world[1]. Moringa trees are an
important food commodity as almost all plant parts are edible
and consumed as nutritive vegetable in many countries[2]. Many
medicinal plants of this family are used in traditional medicine
globely for the treatment of various illnesses. Moringa peregrina
(Forssk.) Fiori (M. peregrina) is commonly known as horseradish
tree or drum stick tree in English and Habb Elyasar or Yen in
Arabic, which grows wildly in Oman. It is grown in many areas
of the world like Northeastern tropical Africa, Madagascar and
Arabia[3]. It is a small, deciduous tree, 6-10 m tall that grows in the
most arid locations such as in drained places in a wadi and on the
hillsides[4]. It is reported that M. peregrina is more drought tolerant
than Moringa oleifera (M. oleifera), which is widely cultivated in
tropical and subtropical areas[5]. Its leaves are large (up to 30 cm
long) and pinnately divided into opposite or alternate blue green
leaflets[3].
