Moringa oleifera and M. peregrina are robust and fast-growing trees. These trees are considered some of the most highly valued trees worldwide because of their properties and uses. This study aimed to investigate and determine the content of phytochemical and nutrient compounds in the fresh leaves and the mature seeds of both M. oleifera and M. peregrina. The experimental data analysis showed that all four extracts were rich in proximate minerals, fatty acids (FA), and un-saponified and polyphenolic components. The total percentages of saturated and unsaturated fatty acids compounds obtained from the leaves and seeds of M. oleifera and M. peregrina were (45.02 and 54.93%), (10.80 and 89.19%), (37.13 and 62.8%), and (11.95 and 88.03%), respectively. The major polyphenols compositions were identified as gallic acid, chlorogenic acid, methyl gallate, and coffeic acid. The outcomes of the present study indicate that the leaves and seeds of Egyptian Moringa (M. oleifera and M. peregrina) contain various phytochemical and nutrient compounds, which can provide several health advantages and play an important role in the metabolism of the human body, especially in diseases such as atherosclerosis, heart disease, obesity, and high cholesterol and triglycerides.

Moringa is a mono-genus belonging to the Moringaceae family, which includes 13 species. Among them, Moringa peregrina is plant species native to the Arabian Peninsula, Southern Sinai in Egypt, and the Horn of Africa, and comprehensive studies on its nutritional, industrial, and medicinal values have been performed. Herein, we sequenced and analyzed the initial complete chloroplast genome of Moringa peregrina. Concurrently, we analyzed the new chloroplast genome along with 25 chloroplast genomes related to species representing eight families in the Brassicales order. The results indicate that the plastome sequence of M. peregrina consists of 131 genes, with an average GC content of 39.23%. There is a disparity in the IR regions of the 26 species ranging from 25,804 to 31,477 bp. Plastome structural variations generated 20 hotspot regions that could be considered prospective DNA barcode locations in the Brassicales order. Tandem repeats and SSR structures are reported as significant evidence of structural variations among the 26 tested specimens. Furthermore, selective pressure analysis was performed to estimate the substitution rate within the Moringaceae family, which revealing that the ndhA and accD genes are under positive selective pressure. The phylogenetic analysis of the Brassicales order produced an accurate monophyletic annotation cluster of the Moringaceae and Capparaceae species, offering unambiguous identification without overlapping groups between M. oleifera and M. peregrina, which are genetically strongly associated. Divergence time estimation suggests that the two Moringa species recently diversified, 0.467 Ma. Our findings highlight the first complete plastome of the Egyptian wild-type of M. peregrina, which can be used for determining plastome phylogenetic relationships and systematic evolution history within studies on the Moringaceae family.
