Abstract:
The effect of sun, oven and solar drying on the nutrients and non-nutrients composition of leaves of Leptadenia hastata was investigated. All the drying methods were found to significantly decrease (p<0.05) magnesium content in sun (1.49±0.49 mg 100 g-1), followed by oven (1.27±0.06 mg 100 g-1) and the lowest in solar dried (0.93±0.07 mg 100 g-1) leaves compared to fresh sample. Drying methods with exception of oven drying did not significantly (p>0.05) lower lipids content. The drying processes employed significantly (p<0.05) decreased carbohydrate, crude protein, magnesium and moisture content. Potassium, ash and crude fibre were significantly (p<0.05) increased. Oven drying significantly reduced acid value (2.82±0.41%), followed by sun (2.12±0.65%) and solar drying (1.76±0.21%) in decreasing order. Tannins, saponins, volatile oils, saponin glycosides and alkaloids were detected in fresh and dried samples. These compounds with exception of saponins and saponin glycosides (sun and oven dried) decreased in trace amounts upon drying. The results reinforce the growing awareness that the leaves of Leptadenia hastata can contribute useful amounts of nutrients to human diets and reduction of toxic non-nutrients compounds upon drying.
