The Solanum genus members belonging to Solanaceae family contain several secondary metabolites distributed in their organs. Present attempt is to know the distribution and quantification of various phytochemicals such as total phenols, tannins and alkaloids. The extracts prepared from root, stem and leaves of Datura stramonium, Solanum nigrum, Solanum melongena, Capsicum anum and Lycopersicon esculentum have been subjected to qualitative and quantitative analysis. The results showed varying distribution profiles of the phytochemicals investigated. The root samples of S. nigrum, S. melongena, C. anum and L. esculentum are qualitatively rich in alkaloids whereas Datura stramonium was found to contain the alkaloids in the root, stem and leaf samples. The quantitative analysis for phytochemicals established that the arial parts of C. anum, L. esculentum and D. stromium contained more phenolics and tannins than their corresponding roots.
