- چکیده:
- چکیده انگلیسی: The essential oils of leaves and flowers of Peucedanum ruthenicum (M. Bieb.) Rochel (Umbelliferae) were prepared by hydrodistillation separately and analyzed by GC and GC-MS, and the composition of both essential oils were compared together. Sixteen and eleven compounds were identified in leaves and flowers essential oils representing 100% and 96.4% of total oils, respectively. The major components were thymol (57.79%), b-bisabulene (6.10%) for the leaves oil, germacrene-D (45%) and germacrene-B (18.5%) for the flowers oil. The amounts of monoterpenes and sesquiterpenes were not found nearly to be equal in oils of the two parts of the plant.
