Medicinal plants are very important in terms of health, technology and economy. Gundelia tournefortii L is a popular medicinal plant that belongs to Asteraceae family. Sixty individuals of the species were collected from four major habitats in Chaharmahal Bakhtiari province including Taghanak, Dastena, Hirkan and Sheyda and one habitat in the south parts of Isfahan province (Komeh) based on the available vegetation type maps and existing knowledge. The essence of plant samples were extracted using Clevenger apparatus by steam distillation method and their chemical compounds of volatile oil were identified using Gas Chromatography Mass Spectrometery (GC/MS). The most important ecological features of the sites such as climate, soil and physiographic conditions were determined. RDA ordination analysis was used to explore the relationships of major chemical compounds of Gundelia tournefortii L. with the environmental factors. The results showed that the first axis of ordination plot with gravel percent, the second axis with soil depth and the third axis with average of annual precipitation, Domarten drought index and length of drought period were significantly correlated. The sites were classified in three habitat groups. Soil depth, average of annual temperature, average of maximum annual temperature, average of minimum annual temperature, average of annual frozen days, annual potential evapotranspiration, annual transpiration and terpene qualitative index were identified as the most important environmental factors affecting Gundelia tournefortii L. habitats.
