Abstract. The purpose is to study the features of biology (the onset of the main phenological phases of seasonal growth and development, the morphology of the vegetative and generative spheres, laboratory germination of seeds, vegetative reproduction) and the chemical composition (above-ground part in various phases of vegeta- tion) of Chrysanthemum zawadskii under the conditions of the South Ural Botanical Garden Institute of UFRC RAS. Methods. Introduction tests (study of phenology, morphometry, etc.) were carried out according to standard methods. Germination of own reproduction seeds is carried out in accordance with the procedure in laboratory conditions in petri dishes in two versions: without stratification and with preliminary stratification. Qualitative and quantitative determination of ash, macro- and trace elements, and some biologically active substances con- tained in the aboveground part of Ch. zawadskii was carried out using known and modified techniques. Results. Ch. zawadskii is characterized by the complete life cycle of development, a long-growing plant (155 days), with late-spring growth of shoots, from the group of long-flowering plants (more than 20 days). Seeds ripen massively in mid-September. The studied rare species has medicinal properties due to the content of certain groups of bio-logically active substances in the above-ground part of plants. A study of the chemical composition in various developmental phenophases showed that the highest content of ascorbic acid and flavonoids is observed in grass collected in the flowering phase, tannins in a larger amount accumulate in leaves collected in the fruiting phase, and in a smaller amount in flowers collected in the flowering phase. The greatest accumulation of organic acids and extractive substances is observed in plant flowers collected in the flowering phase. More macro- and trace elements in Ch. zawadskii accumulates in grass and leaves, regardless of the phenological phase of development. The presence of eight essential and six replaceable amino acids has been established. Scientific novelty. For the first time in the Republic of Bashkortostan, the chemical composition of the Ch. zawadskii, a rare resource medicinal plant, was studied.
Keywords: Chrysanthemum zawadskii, phenology, raw materials, chemical composition, flavonoids, tannins, amino acids.
