Chemical Composition of the Essential Oil of Two Tanacetum Species from Iran

Abstract

The genus<em> Tanacetum </em>L. is one of the most important medicinal plant that contains 28 species in Iran, 12 of them are endemics. This paper reports the essential oil composition of <em>Tanacetum hololeucum</em> (Bornm.) Podlech; <em>Tanacetum kotschyi</em> (Boiss.) Grierson, growing wild in Iran. Plant flowers were collected from different zones of Dizin in north of Iran. All samples were hydro-distilled (Clevenger apparatus), to produce the oils in <em>T. hololeucum</em> from three zones with yields of (0.35%, 0.35% and 0.16%), and also <em>T. kotschyi</em>, from three zones with yields of (0.57%, 0.41% and 0.10%), respectively. All samples were injected to GC and GC/MS. Main components for <em>T.hololeucum</em> from Dizin of three places from zone 1 were borneol 39.4%, trans- sabinene hydrate 8.4%, 1,8-cineole 8.1%, and from zone 2 were n-hexadecane 14%, elemol acetate 13.6%, trans-thujone 13.4%, and from zone 3 were terpinolene 35.7%, α- phellandrene 23%, γ- eudesmol 7.1% , and in <em>T. kotschyi </em>also from Dizin of three places from zone 1 were 1,8-cineole 27.8%, terpinolene 13%, trans-thujone 7.2%, and from zone 2 were n-undecane 27.9%, n-hexadecane 14.7%, n-nonadecane 8.7% , and from zone 3 were n-tridecane 55.1%, terpinolene 13.4%, myrcene 7%, respectively.
