Chemical composition of the essential oil of Cymbopgon olivieri aerial parts by GC-MS

Abstract

<strong><span>Background & aim</span></strong><span>: <em>Cymbopogon olivieri</em> is a perennial plant that grows naturally in Iran. In this study, the essential oil composition of the aerial parts of Cymbopogon olivieri collected from around </span> the khash city was studied.<br /><br /> <strong>Experimental</strong>: The essential oil of plant materials were isolated by hydro-distillation method using Clevenger apparatus. Then, analysis and identification of essential oil composition were carried out by GC and GC- MS techniques.<br /> <strong><span>Results</span></strong><span>: The yield of essential oils collected in April and January were 2.49% (w/w) and 1.21% (w/w), respectively. In the essential oil of the plant collected in April, 19 compounds were identified, which accounted for 98.86% of the total weight of essential oil. The main components of this essential oil were Piperiton (51.65%), Elemol (12.37%),α –Terpinolene </span> (6.09%),Germacrene (4.66%). In the essential oil of the plant collected in January, 20 compounds were identified, which accounted for 99.65% of the total essential oil. The main components of this essential oil were Piperiton (43.06%), Elemol (32.72%), beta-Eudesmol (13.42 %) ,Cathcol (4.62%). <br /> <strong><span>Recommended applications/ industries</span></strong><span>: Most of the compounds in the essential oil of this species are considered as effective pharmaceutical compounds and therefore can be used in the pharmaceutical industry.</span>
