Methods of extraction of anthocyanine dye from ordinary cherries are investigated. The choice of solvents is due, firstly, to the fact that the boiling points are in about the same range, which will allow removal of the solvent at concentration of the extract obtained without degradation of the resulting substances. Secondly, the solvents have different polarity, which allows extraction of cherries from different berries by the structure of the compound (70% ethyl alcohol, 96% ethyl alcohol, water, chloroform). The dye extraction parameters, the ratio of the amount of dye to the amount of the solvent, the extraction time are selected. The content of the dye in the extract is determined.
