Chemical Composition of the Essential Oil of Tanacetum polycephalum subsp. polycephalum from Different Locations of Azerbaijan Province, Iran

Abstract

The genus <em>Tanacetum</em> is one of the most important medicinal plant that contains 26 species in Iran, 12 of them are endemic. This paper reports the essential oil (EO) composition of <em>Tanacetum polycephalum</em> subsp. <em>polycephalum</em> growing wild in Iran. Flowers and leaves were collected from different location of Azerbaijan province (Marand, Mianeh and Tabriz), hydro-distilled to produce the oils and analyzed by gas chromatography/mass spectrometry (GC/MS). The yields of leaves and flowers oils were in the range of 0.04 -1.0% (V/W). Main components of leaves EO from Marand, Mianeh and Tabriz were 1,8-cineole (63.5%) and chrysanthenone (5.5%), while for flowers were chrysanthenone (39.5%) and 1,8-cineole (18.9%). For Mianeh sample, principal components of leaves were 1,8-cineole (34.8%) and chrysanthenone (16.1%) and for flowers were dihydro-eudesmol (12.0%) and nootkatin (9.6%). Camphor (29%) and 1,8-cineole (14.3%) were identified as the main constituents of plant leaves from Tabriz and for flowers were trans-sabinene hydrate (56.7%), and 1,8-cineole (10.7%).
