Abstract: This research has comparatively studied the effects of changes in height, ecological and environmental factors on the type and amount of the chemical compounds of Artemisia sieberi Besser in three different ecological niches of Kashan: near Marjanab Salt Lake (high saltiness), near the sandy hills of Marjanab Desert (sandy), and mountain hills of Ghamsar road - Kashan – (gritty). Essence extraction was done by distillation of water. Decomposition and identification of the consisting elements of the essence was carried out through GC, GC/Mass tools. High amount of precipitations, height above the sea level, concentration of the plant, concentration of the accompanying species, low saltiness of the soil and also high amount of the main elements (microelements) in Ghamsar region is indicative of a better ecological condition which resulted in the high concentration of the total extracted essence, the percentage of the compounds of the essence and the strong scent of the extracted essence in this region. The region near the gritty hills which had the weakest soil form the point of view of having soil nutrients, lower average concentration of Artemisia sieberi Besser and average concentration of the accompanying species had also the lowest total amount of extracted essence, lowest percentage of the components of the essence and the lowest scent. The highest compound belonged to the compound of Borneol was witnessed in the mountain regions of Ghamsar.
