“…Interestingly, the positive correlation between sodium and potassium associated with the low sodium and high potassium content with a high K/Na ratio (K/Na = 23) of spider plant leaves is an important outcome and shows the potential of the species in addressing cardiovascular risk, blood pressure, maintaining electrolyte balance and muscular function. This agrees with previous reports on the richness of green leafy vegetables as a source of potassium (Ejoh et al, 2021).…”

“…The consumption of 100 g fresh leaves of G. gynandra may provide between 5 and 7% of the RDA to adolescents and adults, respectively. This observation agreed with previous reports on the low contribution of the species and some other leafy vegetables to the diet for zinc (Gowele et al, 2019;Ejoh et al, 2021). However, spider plant could be a good source of zinc (19.84% of the RDA) for infants between 1 and 3 years old (see Supplementary Table 3).…”

Understanding the genetic variability within a plant species is paramount in implementing a successful breeding program. Spider plant (Gynandropsis gynandra) is an orphan leafy vegetable and an extraordinary source of vitamins, secondary metabolites and minerals, representing an important resource for combatting malnutrition. However, an evaluation of the leaf elemental composition, using a worldwide germplasm collection to inform breeding programs and the species valorization in human nutrition is still lacking. The present study aimed to profile the leaf elemental composition of G. gynandra and depict any potential geographical signature using a collection of 70 advanced lines derived from accessions originating from Asia and Eastern, Southern and West Africa. The collection was grown in a greenhouse using a 9 × 8 alpha lattice design with two replications in 2020 and 2021. Inductively coupled plasma–optical emission spectrometry was used to profile nine minerals contents. A significant difference (p < 0.05) was observed among the lines for all nine minerals. Microelements such as iron, zinc, copper and manganese contents ranged from 12.59–430.72, 16.98–166.58, 19.04–955.71, 5.39–25.10 mg kg−1 dry weight, respectively, while the concentrations of macroelements such as potassium, calcium, phosphorus and magnesium varied in the ranges of 9992.27–49854.23, 8252.80–33681.21, 3633.55–14216.16, 2068.03–12475.60 mg kg−1 dry weight, respectively. Significant and positive correlations were observed between iron and zinc and calcium and magnesium. Zinc, calcium, phosphorus, copper, magnesium, and manganese represented landmark elements in the genotypes. Eastern and Southern African genotypes were clustered together in group 1 with higher phosphorus, copper and zinc contents than Asian and West African lines, which clustered in group 2 and were characterized by higher calcium, magnesium and manganese contents. An additional outstanding group 3 of six genotypes was identified with high iron, zinc, magnesium, manganese and calcium contents and potential candidates for cultivar release. The genotype × year interaction variance was greater than the genotypic variance, which might translate to phenotypic plasticity in the species. Broad-sense heritability ranged from low to high and was element-specific. The present results reveal the leaf minerals diversity in spider plant and represent a baseline for implementing a minerals-based breeding program for human nutrition.

This study investigated the consumption pattern of wild edible green leafy vegetables found in Osogbo Local Government Area of Osun State using a descriptive survey research design. The sample size for this study was two hundred and eleven (211) respondents. A four-likert scale structured questionnaire containing twenty-four (24) items was used for data collection. Data were analysed using mean scores and standard deviation. The findings of the study revealed that ”Yarin,” “Worowo,” “Gbure,” and “Ebolo" are major wild edible green leafy vegetables found in the study area, and their consumption is quite low. The finding showed that wild edible green leafy vegetables have benefits such as alleviating malnutrition at no cost and can be a good source of income. The findings also showed that urbanisation's preference for cultivated vegetables over wild edible green leafy vegetables, as well as uncultured ideas like ignorance and poverty and well-researched information about cultivated leafy vegetables, are among the factors influencing the intake of wild edible green leafy vegetables. The findings of this study asserted that wild edible green leafy vegetables, when compared with cultivated ones, can alleviate malnutrition, prevent micronutrient deficiency, and equally serve as a source of income at little or no cost. Therefore, it was recommended that there is a need to explore, analyse, and document that wild green edible leafy vegetables are nutritious, health-promoting, and easy to cultivate, and bring out substantial yields even under difficult climatic and edaphic conditions.
