Abstract:Some plants of the family solanaceae such as Solanumdubium"Gubbain", (20-90 °C). The results of substrate specificity of the enzyme showed that the partially purified enzyme preferred both hydrophilic and hydrophobic amino acid residues at P1 position. The catalytic efficiency of the purified enzyme was enhanced by an aliphatic amino acids (Leu) compared to aromatic residue (Phe) at P1 position at the same site.And the morphology of solanum seeds was studied with scanning electron microscopy of mucilage at different magnification using Philips, Lancashire,6,7). Also the fractionation of structure was observed with infera red spectroscopy in figure (8). In this study some metals was determined like Mn , Cr, Cd , Zn. , Fe, and basic element like Ca ,Mg , K , P
