Volatile Oil Constituents of Different Parts of Artemisia Chamaemelifolia and the Composition and Antibacterial Activity of the Aerial Parts of A. Turcomanica from Iran

Abstract

The essential oils obtained by hydrodistillation from the aerial parts, stem, leaf and flower of Artemisia chamaemelifolia Vill. and the aerial parts of A. turcomanica Gand. were analyzed by GC and GC/MS. Thirty-one compounds representing 96.6%, 94.6%, 93.2% and 91.0% of the oil were identified in the aerial parts, stem, leaf and flower oils of A. chamaemelifolia. Menthyl acetate (26.5%, 22.0%, 20.5% and 20.5%) and (Z)-nerolidol (20.8%, 26.3%, 14.7% and 18.1%) were the main constituents in the aerial parts, stem, leaf and flower oils, respectively. The other main component in the aerial parts, leaf and flower oils was 1, 8-cineole (13.9%, 11.7% and 12.8%, respectively). Yomogi alcohol (10.4%) and artemisyl acetate (10.4%) were the main components of the leaf and flower oil of the plant, respectively. No significant difference was observed between compositions of the aerial parts, stem, leaf and flower oils. Twenty-four compounds representing 90.5% of the oil of the aerial parts of A. turcomanica were identified, of which 1,8-cineole (15.5%), spathulenol (15.2%), camphor (14.8%), santolina alcohol (14.6%) and trans-beta-terpineol (11.6%) were the major ones. The stem, leaf and flower oils of A. turcomanica demonstrated antibacterial activity using the MIC method.
