This study was aimed to evaluate and compare phytochemical and mineral elements in young and mature leaves of V. amygdalina. The young leaves contained (0.281 g/100g) flavonoid,(0.397 g/100g) phenols,(0.064 g/100g) saponin,(1.4731 g/100g) alkaloids with the mature sample containing (0.371 g/100g) flavonoid,(0.642 g/100g) phenol,(0.072 g/100g) saponins and (1.621 g/100g) alkaloid. Magnesium, potassium, phosphorus, and calcium were the mineral elements determined in the young and matured leaves of V. amygdalina. The young leaf contained 105 (mg/kg) potassium, 113.15 (mg/kg) calcium, 134.65 (mg/kg) magnesium and 21.85 (mg/kg) phosphorus with the mature leaf containing 96.25 (mg/kg) potassium, 117.6 (mg/kg) calcium, 141.45 (mg/kg) magnesium and 19.75 (mg/kg) phosphorus. The mineral analysis of both leaves extracts showed that as the leaf matures the concentration of potassium, and phosphorus reduces, but the matured leaf contains more calcium and magnesium than the young leaf. Quantitative analysis of the extracts showed that the mature leaf contains more flavonoid, phenol, saponin and alkaloid than the mature leaf. From the findings of this study, it shows that though the leaves of both young and matured V. amygdalina has therapeutic properties and can be used in dietary supplements, the mature leaf has more concentration of phytochemical and mineral elements than the young leaf.
