Identification of scientific regularities of accumulation of physiologically active compounds is relevant to the issues of plant biology, as it can create conditions for the rapid development of biotechnological approaches and the solution of a number of environmental and economic problems associated with the use of plant raw materials. The aim of this work was to identify the features of the accumulation of flavonoids and the development of methods of differential spectrophotometry allows to assess the quality of biotechnological raw materials Iris sibirica L. (Siberian iris) on the content of flavonoids.
The most important regulators of the synthesis of secondary compounds in plant tissue cultures include such components of nutrient media as hormones. As a result of our experiments it was noted for I. sibirica characteristic relationship between the accumulation of biomass and the content of quercetin and rutin. On the medium with 5.0 µm BAP, supplemented by auxins with an increase in the total height of the shoots, the quercetin content and rutin in the phytomass decreased dramaticly. To maintain a balance between biomass accumulation and flavonoid content for I. sibirica, we recommend using media with 2.5 µm BAP supplemented with auxins.
The developed method allows to determine the content of the total of flavonoids in Iris sibirica raw materials in the presence of other compounds, is simple in execution and does not require expensive equipment. A validation evaluation of the technique indicates its suitability for quality control of biotechnological raw materials Iris sibirica.
