Chemical Composition of Hydrodistillation Essential Oil of Rosemary in Different Origins in Iran and Comparison with Other Countries

Abstract

2 Abstract: In the present work, chemical composition of essential oils of rosemary (Rosmarinus officinalis L.) from various geographic origins (Kerman and Lalehzar) were determined by GC/MS. Rosemary leaves oil was isolated by hydrodistillation. The 49 components were identified in Lalehzar oil and 31 components were identified in Kerman oil. The hydrodistillation of Lalehzar oil was found to be rich in -pinene (43.9%), 1, 8-cineole (11.1%), camphene (8.6%), -myrcene (3.9%), broneol (3.4%), camphor (2.4%) and Verbenol (2.3%). 31 components were identified in hydrodistillation of Kerman oil and main component as follow; -pinene (46.1%), 1, 8-cineole (11.1%), camphene (9.6%), camphor (5.3%), sabinene (4.6%), -myrcene (3.9), broneol (3.4%), bornyl acetates (2.8%), verbenone (2.3%) and linalool (2.1%).
