Abstract
The article describes the method of spectrophotometry. Materials and methods. The objects of research were extracts from vegetative parts and fruits of red mountain ash (Sorbus aucuparia). In the process of scientific research, solvent ranges with acidic, neutral and alkaline media were selected. The study of the optical properties of the extracts was verified by using spectrometry, using the KFK-2 device. In the course of work, experimental samples of extracts were studied according to the following indicators: color intensity (I, e.d.), color shade (T, e.d.), chromatographic structure (%) and the content of the sum of anthocyanins (in terms of cyanidin-3,5-diglycoside, %). As a result of experimental studies, mathematical data processing was carried out with the calculation of average values and standard deviation. Analysis of quantitative data on the color and transparency of samples showed a relationship between the color intensity index (I, e.d.) and the content of anthocyanins (in terms of cyanidin-3,5- diglycoside, %), that with an increase in optical density at a wavelength of λ=440, 540 and 670 nm, the content of anthocyanin complexes in the Sorbus extracts under study increases aucuparia. According to the analysis and data processing, it is recommended to use water with an alkaline medium as a solvent for the isolation of anthocyanin compounds in the study of the blue component (λ= 670 nm) determined the content of free anthocyanins in quinone form.
