Composition and Antibacterial Activity of the Essential Oils From Aerial Parts, Stems, Flowers and Leaves of Ferulago contracta From Iran

The essential oils obtained by hydrodistillation from the aerial parts, stems, flowers and leaves of Ferulago contracta Boiss. et Hausskn, which is endemic to Iran, were analyzed by GC and GC-MS. beta-phellandrene (15.1 %, 15.3 % and 25.0 %) and alpha-phellandrene (14.4 %, 11.5 % and 25.0 %) were the main constituents in the aerial part, stem and flower oils of F. contracta respectively. The other main components in the aerial part oil of the plant were beta-eudesmol (10.9 %) and (E)-beta-ocimene (10.0 %) and in the stem oil was also (E)-beta-ocimene (11.3 %). The leaf oil of the plant was characterized by higher amount of beta-eudesmol (24.5 %), spathulenol (16.2 %) and citronellol (11.9 %). The antibacterial activity of stem, leaf and flower oils of Ferulago contracta against seven gram positive and gram negative bacteria were determined using MIC method. The growth inhibitory zone (mm) were also measured.
