The aim of the work was to determine the spectrophotometric criteria for the stability of anthocyanins of plant materials. On the basis of the numerical indicators of absorption spectra, the relationship between the stability of the extracted anthocyanins and the original color of the raw material was determined. The research used raw and dried plant parts of 33 species from different families. The stability of anthocyanins was determined as the ratio of relative absorbances and intensities of absorption bands in the optical spectrum of the extract. It has been shown that anthocyanins are the most stable in extracts from fruits with burgundy-violet and black colors. Anthocyanins from blue raw materials have the lowest resistance. The resistance of anthocyanins from red raw materials ranks between "burgundy" and "blue". The anthocyanidins peonidin and malvidin are more stable in comparison with petuidin, pelargolin and cyanidin, and delphinidin is the least stable during technological drying of raw materials.

It is advisable to use the spectrophotometric criterion of anthocyanin resistance in express analysis when selecting promising plants for industrial cultivation and production of anthocyanin-containing phytopreparations.
