THE COMPONENT COMPOSITION OF THE TRAGOPOGON ORIENTALIS VOLATILE CONSTITUENTS AND ITS BIOLOGICAL ACTIVITY

Abstract

The purpose of this study is the chemical investigation of the composition of Tragopogon orientalis volatile constituents (VC) and studying of its biological activity. This article presents the results of research on the study of the chemical composition of species Tragopogon, as well as data of antiradical and cytotoxic activity. To study the dried and crushed aboveground part of the plant (leaves, flowers and stems) was taken, The raw material was collected in the flowering phase, growing in Northem Kazakstan, The VC was isolated from the plant of Tragopogon orientalis by hydrodistillation method on the Clevenger type apparatus. The chemical composition of the VC was determined by GC/MS. The cytotoxic activity of the VC was determined by the survival rate of sea shrimp Artemia salina. VC of T. orientalis in all studied concentrations (1-10 mg ml-1) exhibit acute lethal toxicity - all larvae die. Antiradical activity was determined by the method of colorimetry of free radicals (DPPH). The experimental results showed that the VC of T. orientalis at all tested concen- trations (0.1-1.0 mg ml-1) exhibit low antiradical activity compared with the butylhydroxyanisole standard drug.
