Determination of mineral composition of Iraqi Nigella Sativa L. seed by Atomic absorption spectrophotometer

الملخص

The elements are widely distributed in nature with variable proportions, which
lead to variation in foods intake of these elements according to their sources in plants or
foodstuffs.
These elements play a vital role in growth, health and maintenance of human
body.
In this study the macronutrients elements (Ca, P, S, Mg, K, Na) and trace elements (Zn,
Fe, Cu, Mn, Se) were measured in the seed oil of Nigella sativa by using atomic
absorption spectrophotometers. The results observed the presence of significant
quantities of the above elements which to be considered as a good source of trace
elements supplimination to human body by used the oil of nigella sativa in certain
amounts.
