Abstract

Proximate composition and levels of metals in four commonly consumed species,Sonchus erucaMelia azadirchtaWithania cogulus and Fagonia indica, were investigated for the first time. Ash, carbohydrate, protein, fiber, fat and moisture were arranged on dry basis, while Cu, Pb, Co, Cd, Fe, Cr, Mg and Na were also investigated in metal analysis using association of official analytical chemists (AOAC) methods and atomic absorption spectrometric techniques. However, M. azadirachta was found to be rich in fiber content and energy values. The results of metal analysis showed that M. azadirachta had the highest concentrations of the metals like Cu, Mn, Cr and Fe while S. eruca contain higher concentration of Na as compared to other three species.

 

Key words: Sonchus erucaMelia azadirchtaWithania cogulus and Fagoniaindica, proximate composition, metal analysis.
