Extraction and study anthocyanins plant material

The paper presents the results of the qualitative and quantitative determination of some anthocyanins (in particular, cyanidin-3-glycoside and cyanidin-3-galactoside) in the fruits of Aronia melanocarpa (Michx.) and Mahonia aquifolium (Pursh) Nutt. The reaction of extracting water-soluble dyes on the solution medium is also presented. The method of direct spectrophotometry was used. All calculations are made in the program STATISTICA 6. It is determined that the maximum content of anthocyanins is typical for fruit chokeberry Aronia. The possibility of using natural dye from chokeberry fruits in the industry is shown.
