Abstract
Determination of mineral composition of the selected vegetable lactuca sativa which is
commonly used as food. Macroelement Sodium (Na), Potassium (K) and Iron (Fe) were
analyzed using AAS and Flame-photometric techniques the microelement including Fe is
found to be )7.03 ppm(; The results of macroelements obtained having values Na (9.61 ppm)
and K (32.67 ppm); The results indicated that this vegetable has the potential to provide
essential nutrients to the human beings and it is found to be a good source of Fe, Na and K.
The present method is accurate, the average recovery of Na, K and Fe were 100 %, 100.6 %
and 105.8, respectively and precise the RSD is < 5%, <2 %,> 2% for Na, K and Fe
respectively.
Key words: lactuca sativa, Atomic absorption spectrometry (AAS), Flame photometry.
