Abstract
Panzerina lanata subsp. argyracea (Kuprian.) Krestovsk. is a valuable drug plant that grows in Khakassia. It contains a complex of biologically active compounds including flavonoids. Resources of panzerina raw material steadily go down owing to anthropogenic load. Its domestication solves the problem of its preservation. A wild-growing cenopopulation with the greatest content of flavonoids in the aboveground part has been revealed that is of interest as a starting material for plant introduction. The content of flavonoids in particular members of plants Panzerina lanata subsp. argyracea that grows in various cenopopulations of Khakassia and under conditions of plant introduction has been examined. Dynamics of accumulation of flavonoids for strange silvery panzerina has been determined in various vegetation phases. It was found that plants in the crop exhibit a high level of variability in their content of flavonoids.
