Micronutrient malnutrition is a global challenge. However, there are
promising opportunities for combating it through the consumption of
neglected and underutilized leafy green vegetables. Senecio biafrae is an
underutilized and nutrient-rich green leafy vegetable with huge nutritional
and health potentials that have remained unexploited. The aim of this
research was to evaluate the proximate, mineral, vitamin, anti-nutrient
contents of the leaves of Senecio biafrae. Leaves of Senecio biafrae were
collected from five communities in Ekiti State and analyzed using standard
biochemical methodologies. The results showed that the leaves differed
significantly in nutritional and anti-nutritional contents. The leaves were
rich in potassium, magnesium, and calcium, and low in fat and anti-nutrient
contents for all the groups studied. The Pearson’s correlation results
showed that most of the nutritional parameters either had inverse or no
relationships with anti-nutrients. The crude protein showed significantly
positive correlations with dry matter (0.90**) and a negative correlation
with cyanogenic glycosides (-0.90**). Cyanogenic glycosides showed
significantly negative correlations with potassium (-0.63**), calcium
(-0.66**) and dry matter (-0.44*). Nitrate showed no significant
relationship with any nutritional parameter. Oxalate and tannin showed no
significant relationship with the vitamins. Phytate and tannin showed no
significant relationship with the proximate contents and minerals. The
results showed that Senecio biafrae leaf is nutrient-rich and could help to
mitigate the effects of micronutrient deficiencies. The variations and
relationships among the nutritional and anti-nutritional parameters could
enhance meaningful selection and nutritional quality through breeding.
