“…Determination of elemental micro-nutrients were carried out as reported by Mafokoane et al [17]. In brief, a total of 10 g of dried leaf sample material were digested in 40 mL of 4% nitric acid (HNO3), followed by placing the container on a vortex to allow for the complete wetting of the mixture.…”

“…The materials were magnetically stirred, and thereafter incubated in a 95_°C water bath for 90 min, before being allowed to cool down at room temperature, filtered, and decanted into 50 mL tubes which were covered with foil, and then selected nutrient elements were analysed using inductively coupled plasma optical emission spectrometry (ICPE-9000). The conditions of the analysis and the development of the mineral standard curve were as reported by Mafokoane et al [17].…”

This study aimed to assess the variations in the nutritional attributes of thirteen Moringa oleifera cultivars. Leaves from six-month-old plants were harvested and tested for various nutritional attributes. There were significant (p ≤ 0.05) differences in the carbohydrates, energy, some of the sugars and fibre amongst the cultivars. The levels of moisture in the cultivars ranged from 7.10% to 8.20%. Additionally, there were significant (p ≤ 0.05) differences across the cultivars in microelements studied except for zinc (Zn). These data revealed that plants from different geographical provenances differed in their adapting to varied environments. In general, under the same cultivation, management and environmental conditions, the main reasons for these differences occurred in cultivars could be associated with the genetic background of each M. oleifera germplasm. However, the study cautions on the differences of nutritional properties, as some of the cultivars have been reported not to be pharmacological potent.
