Characteristics of some biologically active substances of a number of terpenes for representatives of the Crassulaceae DC family the Genus sedum S.L., growing in the RSO–Alania

Sedums are representatives of the Crassulaceae family, a valuable medicinal species with limited distribution. It is of exceptional importance for herbal medicine and plant biochemistry. At the Federal State Budgetary Educational Institution of Higher Education Gorsky State Agrarian University, some representatives of the Crassulaceae family (Crassulaceae DC) have been introduced and successfully grow in the collection nursery: prominent sedum, Caucasian sedum, antifolia sedum and linear sedum. Crassulaceae DC. is a large family of dicotyledonous angiosperms characterized by its unique form of photosynthesis. These plants are used mainly as carriers of chemically active compounds and biologically valuable substances. The studied samples of plants of the Crassulaceae family are of particular interest as raw materials for medicines and as valuable biologically active components. As a result of the studies carried out using chromatography-mass spectrometry, the component composition of the terpene series in plant objects was determined: sedum oppositifolium, Caucasian sedum (Sedum caucasicum), linear sedum (Sedum lineare Thunb.) and prominent sedum (Sedum spectabile). Sedum spectabile contains two, Sedum caucasicum contains five, Sedum oppositifolium contains eight, Sedum lineare Thunb. – ten components of the terpene series. The biologically valuable substances of a number of terpenes of the Crassulaceae family, found in the studied plants, were determined using organic solvents. Terpenes were isolated in chloroform and ethanol extracts, i.e., a solvent was selected for the component of interest, and the identified terpenes can act as indicators of specific components for each plant and the selection of suitable markers.
