Chemical constituents of essential oil of Dracocephalum moldavica L. and Dracocephalum kotschyi Boiss. from Iran

摘要

Dracocephalum moldavica L. and Dracocephalum kotschyi Boiss. are aromatic plants belonging to Lamiaceae family. The aim of this study was to identify the chemical components of D. kotschyi and D. moldavica from Iran. The aerial parts of D. kotschyi were collected from (Kamu Mountain) Isfahan province and the aerial parts of D. moldavica were collected from Sari (Mazandaran province) North of Iran, during 2014. The essential oil was extracted by a Clevenger approach and analyzed using GC/MS. In total, 32 and 24 compounds were identified in the essential oil from the aerial parts D. kotschyi and D. moldavica , respectively. The results obtained in our study indicated that the major components in the oil D. kotschyi were limonene (23.56 %), carvacrol (14.65 %), γ-terpinene (12.99 %), α -pinene (12.62 %), 2-methyl-1-octen-3-yne (9.73 %), camphene (4.66 %), myrcene (3.65 %) and α -terpinene (3.12 %). The major constituents of the oil D. moldavica were geranyl acetate (36.62 %), geraniol (24.31 %), neral (16.25 %) and geranial (11.21 %). D. kotschyi is one of the important sources of limonene and D. moldavica is one of the important sources of geranyl acetate.
