In this thesis was examined the influence of pH on solubility and precipitation of proteins extracted from the flour of the Cannabis sativa L plant. For this experiment was chosen the pH in the range of 3 to 11. Monoecious breeds of canabis USO 31 and Fedora 17 were chosen for this purpose. Laboratory methods were applied after the protein extraction, in order to define the content of nitrate substances which was the highest at pH 11. Protein spectrums were detected by the SDS-PAGE analysis where especially in an alkaline environment, globuline fraction was present at a greater amount than was the albuminium one. The next step was the isoelectric precipitation of extracted proteins within the variances containing high values of nitrate substances. The content of the nitrate substances in the protein extract was spanning between 56,3 % to 92,9 %. Based on the results of the experiment, is is feasible to conclude that Fedora 17, which was extracted at the alkaline pH 11 and isoelectrically precipitate to pH value 5 and 6, contained the highest amount of protein.
