The paper considers pharmacopoeial approaches to the standardization of flavonoid-containing medicinal plant raw materials (MPRM) from different manufacturers in the Eurasian Economic Union (EAEU) countries. Two or three countries produce 31 names of MPRMs that are standardized according to the content of flavonoids. The breadth of use of this MPRM creates prerequisites for including these types in the common EAEU pharmacopeia. It is proposed to standardize a number of MPRM types, such as birch (Betula) leaves, black elder (Sambucus nigra) flowers, knotweed (Polygonum aviculare) herb, marjoram (Oreganum) herb, common horsetail (Equisetum arvense) herb, and beggarticks (Bidens) herb, according to the content of flavonoids, by using the unified chromatographic conditions for their determination by high performance liquid chromatography (HPLC). Using a new MPRM type (common heather (Calluna vulgaris) shoots) as an example, the authors consider the main stages of HPLC assay validation, by quantifying the amount of flavonoids in the plant materials, as calculated with reference to the analytical marker
