Essential and Trace Elements in Different Pulses, Spices and Vegetables
The amounts of bio-chemically important elements for human bodies such as Na, K, Ca, P, Mg, Fe and Cu in some widely used pulses and spices in Chittagong were determined by using flame photometry and UV-Visible spectrophotometry. Similarly, the amounts of Mg, Fe and Cu in some leafy and non-leafy vegetables available in Chittagong were determined by the UV-Visible spectrophotometric method. The essential elements such as Na, K, Ca and P were found in mg/kg levels. The amounts of trace metal such as Mg, Fe and Cu in pulses and spices were just within the range of human necessity. However, the amounts of Mg, Fe and Cu in leafy and non-leafy vegetables were so negligible that they can not be considered as adequate for health, except their food-values constituted by the higher contents of starch
