USING HIGH PERFORMANCE LIQUID CHROMATOGRAPHY FOR IDENTIFICATION OF HYDROXYCINNAMIC ACIDS IN PLANT RAW MATERIALS (REVIEW). MESSAGE 2

In recent years, the use of high-performance liquid chromatography (HPLC) has become a priority for studying the qualitative composition of hydroxycinnamic acids (HCAs) in plant materials. This is due to the analytical advantages of the method and the ability to expand the range of simultaneously determined characteristics of the objects of study by equipping chromatographs for HPLC with equipment with additional functions. However, the widespread introduction of HPLC methods is limited by the high cost of equipment. The disadvantages also include the need for preliminary sample preparation to separate ballast substances and increase the concentration of the studied biologically active compounds (BACs) at their low content in the plant. The review contains the results of studying and systematizing the use of the HPLC method from 2007 to 2022 inclusive to establish the composition of HCAs in plant materials growing in the territory of the Russian Federation. The study used a retrospective information and analytical analysis of sources of domestic scientific literature.
