Study of biologically active substances of the species Centaura ovina (Pall. et Willd) in the flora of Azerbaijan

Summary

For the first time, the article provides information on C.ovina belonging to the genus Centaurea L. (Asteraceae) containing biologically active substances. There are about 700 species of the genus Centaurea L. in the world. Of these, 49 species are represented in the flora of Azerbaijan, which are used in many industries as a fodder plant, in beekeeping, as a dye (producing red and yellow flowers). The roots, leaves, stems and flowers of species are used in the production of substances of secondary origin: sesquiterpene lactones, coumarins, flavonoids, anthocyanins and tannins, as well as extracts and water tinctures, which are widely used in folk medicine for the treatment of headaches, jaundice, eye diseases, wound healing, as a diuretic, antiallergic. In addition, the plant is widely used in the treatment of many skin diseases, while in Indian traditional medicine it is used to treat diseases of the central nervous system and bronchial asthma. In view of this, it is very important to study the chemical composition of C. ovina, which contains substances belonging to the class of terpenoid compounds. The methods of extraction, column chromatography, and IR spectroscopy were used in the work. As a result of the studies in an individual state, 2 crystalline substances, knitsin and pimpinellin, were obtained.
