| Abstract: | The chemical composition of the essential oils of Dracocephalum kotschyi (Lamiaceae) aerial parts, grown in Iran and obtained from three different methods, were determined by GC and GC/MS. Fifty-seven
compounds (93.3%) in the hydrodistillate oil, 55 compounds (94.2%) in the steam distillate oil, and 34 compounds (98.4%) in
the hydrolate were identified. The major compounds in the hydrodistillate oil were α-pinene (12.1%), methyl geranate (11.2%),
β-ocimene (8.6%), and limonene (7.2%). α-Pinene (15%), methyl geranate (14.5%), limonene (11.2%), and β-ocimene (8.4%) were
the most abundant components in the steam distillate oil. The percentages of geraniol (13%), trans-verbenol (11.6%), and terpinen-4-ol
(11.2%) were more than other constituents in the hydrolate.
