Seeds of Moringa Oleifera: What are they useful for and where to find them
October 12, 2023
The nutraceutical and phytotherapeutic properties of Moringa oleifera extend to almost every part of this plant, from the roots to the leaves.
The seeds are no exception and offer a wide range of uses, not just in the food sector.
Chemical composition of Moringa seeds
The Moringa oleifera tree produces spherical three-lobed seeds not exceeding 1 cm in diameter and not exceeding 0.3 g in weight.
Each seed is contained in a long pod (this is the 'fruit' of the Moringa tree) and is surrounded by a tripartite structure consisting of three 'wings' that radiate from the base and reunite at the top.
A study carried out in 2016 by four researchers from the University of Milan gives the following chemical composition (expressed in grams) per 100 g of dry product for Moringa seeds:
fats (36.7 g);
proteins (31.4 g);
carbohydrates (18.4 g);
fiber (7.3 g);
Moisture (7g)
As for the bioactive compounds, the above research indicates the presence of:
alkaloids (moringin);
flavonoids (including quercetin);
Glucosinolates and phenolic acids. [1]
The production of Moringa seeds is done by
In general, the best seeds are dark in color (brown or black) and are preferred over the whitish ones.
Additionally, seeds in the proximal and middle positions (relative to the origin of the pod) are preferred.
After harvesting, the seeds are dried for a day or two in a well-ventilated, shaded place, away from direct light, be it natural or artificial. [2 ]
The properties of Moringa seeds
Various studies* have shown that moringa seeds have good antioxidant properties due to the above-mentioned phytochemical compounds and can therefore reduce damage caused by oxidative stress associated with aging and cancer.
In another study conducted on mice ("An antitumor preparation from Moringa oleifera Lam") from the Department of Chemistry at the University of the Philippines, one of the compounds isolated in moringa seeds (niazimine) was shown to have a "potent chemopreventive " Agent is due to its "strong anti-tumor promoting activity". [ 3 ]
A study conducted in 2010 ("Improving effects of Moringa oleifera Lam seed extract on liver fibrosis in rats") showed that moringa seed extract can act against liver damage and fibrosis caused by the administration of carbon tetrachloride, due to its antioxidant and anti-inflammatory properties and its liver protective function. [ 4 ]
Further studies have shown additional health benefits of moringa seed extract: it can act as an anti-asthma agent, anti-inflammatory for rheumatoid arthritis, bronchoalveolitis and edema.
In addition, the seed powder can relieve the effects of high blood pressure and ventricular fibrosis. Finally, Moringa seed extract has also been shown to have anti-diabetic properties - these properties have been proven in animal studies. [ 5 ]
Other Uses of Moringa Seeds
The seeds of Moringa oleifera are also used outside of the nutraceutical sector.
The study 'Moringa oleifera and other local seeds for water purification in developing countries', conducted on three islands in the South Pacific (Fiji, Kiribati and Tonga), states that 'The seeds of Moringa oleifera contain proteins that have active coagulating properties and used in many countries to remove cloudiness in water'.
They were found to be more effective than other seeds and showed high potential for purifying drinking water resources in developing countries due to their effective flocculating effects.[6]
Anti-aging cream with moringa seeds
Similar to other parts of the plant, Moringa seeds are also used in the cosmetics industry.
Specifically, they are an essential component of the anti-aging cream with moringa and hyaluronic acid from RedMoringa.
The latter contains a special protein extract which, in combination with plant-based hyaluronic acid in various molecular weights, gives the product pronounced protective (also against environmental damage), regenerating and anti-aging properties.
