Abstract

The study evaluated the proximate, minerals and antinutrient contents of the plant Leptadenia hastata (Pers.) decne (Asclepiadaceae). Nutrient and antinutritional factors were determined using standard analytical methods and parameters subjected to statistical analysis. Manganese (Mn), Calcium (Ca) and Cobalt (Co) were found to be significantly (p<0.001) higher in the leaves when compared to the tender stem while Iron (Fe), Zinc (Zn) and Magnesium (Mg) were found to be significantly (p<0.001) higher in the tender stems when compared to the leaves. The percentages of Moisture content, Crude proteins and Total ash were found to be significantly (p<0.05) higher in the leaves when compared to the tender stem while crude fiber and Nitrogen Free Extract (NFE) was significantly (p<0.05) higher in the stem when compared to the leaves. Oxalate and phytic acid were anti nutrient found to be significantly (p<0.001) higher in the leaves when compared to the tender stem. However, Copper (Cu), Lead (Pb), Potassium (K) and Crude fat were not significantly (p>0.05) different when compared in the leaves and tender stem. Correlation analysis indicated that antinutrient contents in the tender stems will not affect the mineral absorption in the leaves while negative correlation between Fe and Cu in the stems could affect the absorption of iron. Therefore, Leptadenia hastata leave and tender stem consumed in soup and local salad in northern Nigeria proved to be rich in minerals and nutrients to support its dietary role as a consumed vegetable.
