Abstract
The results of a comparative study of the content of biologically active substances in 8 species of the Sedoideae subfamily Aizopsis aizoon (L.) Grulich, A. hybrida (L.) Grulich, A. kurilensis (Vorosch.) S. Gontch., Hylotelephium ewersii (Ledeb.) H. Ohba, Sedum album L., S. hispanicum L., S. rupestre L., S. spurium M. Bieb. are presented: The aboveground shoots collected during the mass flowering phase were analyzed. The dry matter content was determined by drying of raw materials at 100‒105 °C. The amount of phenolic compounds, pectin substances, and total sugars was determined spectrophotometrically using SF-56 (Russia) and Agilent 8453 UV-Vis (USA) devices; the concentration of ascorbic acid was determined by titrimetric method. It was established the content of dry substances (up to 18.94%), flavonols (up to 4.45%), catechins (up to 3.72%), tannins (up to 20.2%), pectins (up to 13.36%), and sugars (up to 39.54%) per mass of absolutely dry raw materials, and ascorbic acid – up to 123.7 mg% per raw mass. A. kurilensis has the greatest capacity to accumulate bioactive substances. The data point to the prospects of stonecrops as a potential source for the production of food and feed additives.
