Chartolepis intermedia Boiss. (Asteraceae), which is also called Centaurea chartolepis Greuter, is a perennial herbaceous plant that is broadly distributed in European Russia, Central Asia, Kazakhstan, and western Siberia [
C. intermedia is well studied. Grosshemin and cynaropicrin, which are of interest because of their biological activity [2-7], were identified in its aerial part [
Previously, the anatomical structure of this plant was investigated by us [
The aerial part of C. intermedia (leaves, flowers, stems) was collected during flowering in the middle of August 2017 in a field near Korgalzhyn highway about 10 km from Astana. The collected raw material was dried and ground. Specimens are preserved in the herbarium of the Biological-Geographic Faculty, E. A. Buketov Karaganda State University, under code 1985.07.10.02.02.
Essential oil was obtained from ground dried plant matter (without rough stems) by steam distillation in a Clevenger apparatus for 2 h [
Table 1 shows that the main constituents of C. intermedia essential oil were β-caryophyllene oxide (5.0%), isospathulenol (4.6%), spathulenol (4.3%), n-hexadecanoic acid (3.9%), germacrene D (3.3%), 1,5-epoxysalvial-4(
