Изучен химический состав водно-спиртовых извлечений из надземной и подземной частей патринии скальной (Patrinia rupestris). Исследования показали, что сырье корневой и надземной частей растения содержит одинаковый набор биологически активных веществ, при этом количество вторичных метаболитов в сырье корня в разы меньше, чем в сырье травы.
The paper gives the analysis of the chemical composition of raw materials and extracts of the root and aboveground parts of Patrinia rupestris, potentially having neurotropic activity. Methods. Raw herbs and roots were procured at the flowering stage (in August). The researchers used standard methods. Results. Content of secondary metabolites was higher in the raw herb, in the roots it exceeded analogous proportion of polysaccharides by 82.5 %, tannins - 34.7 %, pectins - 61.1 %, catechins -224.9 %, carotenes - 20.4 %. Flavonol content in the herb exceeded that of the root part by 12.2 times. The extracts were water-soluble components: polysaccharides, flavonols, tannins. Conclusions. Raw root and aboveground parts of P. rupestris contains the same biologically active substances with the number of secondary metabolites in raw root is significantly smaller than that of the raw herb.
