Fatty Acids Profile and Chemical Composition of Egyptian Moringa oleifera Seed Oils

Abstract

Moringa oleifera is grown all over the world as a crop for its nutritious pods, leaves and seeds. The purpose of the present study was to evaluate the oil percentage, density, iodine value, saponification value, acid value and fatty acid profile of Egyptian moringa Seed oils. Moringa seeds were irradiated using 60Co at dose levels of 0.0 (control), 5, 10 and 15 kGy and oil was extracted from unirradiated and irradiated samples. Results showed that the oil percentage and density were almost unaffected. Irradiation reduced the iodine value, whereas the acid and saponification values were increased in all irradiated samples. The oil was found to contain high levels of unsaturated fatty acids, especially an omega‐9‐fatty acid (oleic) (up to 76.29 %) at a dose level of 15 kGy. Also at the same dose level, the dominant saturated acids were palmitic, stearic acid and arachidic (the three up to 12.66 %). GC–MS revealed the presence of different compounds (more than 50) in the moringa oil extract, among them alkaloids, terpenoids steroids, saturated and unsaturated fatty acids, aromatic and aliphatic hydrocarbons and polyphenolic compounds. Phenolic and falvonoid were significantly increased by increasing irradiation dose levels. Also, the antioxidant activity of irradiated seed oil increased by increasing the phenolic and flavonoid contents. Moringa oleifera could be grown by wide scale production as a potentially valuable crop. However, isolation of individual compounds and their biological activities needs to be covered in future to enhance its pharmacological importance and to open new avenues of research.

Characterization of the Chemical Composition of Chinese Moringa oleifera Seed Oil

“…It is noteworthy that both oils possess very low AV and PV, suggesting their good quality as edible oil. These results are in agreement with (Aly et al, ) those obtained for Egypt . Either iodine value or unsaponifiable matter content of the aqueous enzymatic extracted oil was a little higher than that of the Soxhlet extracted oil ( P < 0.05).…”

Effect of Gamma irradiation on some biochemical properties, antioxidant and antimicrobial activities of Sakouti and Bondoky dry dates fruits genotypes

“…Furthermore, Naresh, Varakumar, Variyar, Sharma, & Sarathi Reddy (2015) indicated that the degradation of conjugated phenolic compounds should define the higher phenolic content in gamma-irradiated date samples. In the same concern Aly, Maraei, & Ali (2016) found that phenolic and flavonoids were significantly expanded by expanding irradiation dose levels of Egyptian Moringa oleifera seed oils. On the other side, Carocho et al (2012) demonstrated that contents of flavonoid decreased in chestnut Table 3.…”

“…Several studies have shown that palm dates include flavonoids such as quercetin, luteolin, and apigenin, as well as phenolics such as ferulic, sinapic, p-coumaric acids, and derivatives of cinnamic acid (Sanchez-Moreno, 2002). The radical DPPH in oil produced by unirradiated and irradiated Moringa oleifera seed oil showed that scavenging activity gradually increased by increasing the amount of irradiation dose to 10 kGy (Aly, Maraei, & Ali 2016).…”

Production of vegetable oils in the world and in Egypt: an overview

“…Moringa oleifera (M. oleifera L.) has been called the "Miracle Tree" because every part of the tree including leaves, oilseed, stem, and roots has a beneficial properties in nutrition or in pharmaceutical purposes (Gopalakrishnan et al, 2016;Aly et al, 2016;Azad et al, 2015). It belongs to the family of Moringaceae, and it is widely cultivated across the world.…”

“…Moringa oil is rich in palmitic, stearic, behenic, and oleic acids. Oleic unsaturated omega-9-fatty acid is about 76.29%, and saturated acids were palmitic, stearic acid, and arachidic up to 12.66% (Aly et al, 2016). The seeds of Moringa oleifera are used in water treatment as natural coagulant.…”
