Due to the side effects of chemical drugs, special attention is given recently to pharmaceutical plants. Myrtle (Myrtus communis L.) is one of the valuable pharmaceutical plants, which is distributed over the vast areas of Iran. Yield and components of essential oil of this plant is dependent on ecological and genetic factors. In order to describe some ecological factors that affect myrtle in Lorestan province, three forest sites (Sepiddasht, Chame-moord, and Hamzeh Camp) were selected. Some effective ecological factors on type of essential oil were measured and compared among the sites. To compare the yield and components of essential oil, myrtle leaves were collected during flowering stage in each site. Leaves were dried in open air conditions and the oil was extracted by distillation. Yield of essential oil was calculated and its components were identified by GC and GC/MS. Results showed that maximum yield belongs to Sepiddasht site. The altitude and soil Na, P, and organic carbon content of this site is quite different from other two sites. The main components of essential oils of these three sites had considerable differences. The amount of 9,10 anthracenedione was 29.1% in Sepiddasht site, while it was not found in the oil of Chame-moord site. It seems that differences in ecological and soil properties of the tree sites could have major effect on essential oil yield and its composition.
