In order to determine the morphophysiological and phytochemical properties of various Ducrosia anethifolia populations, the plant samples were collected from 20 locations in native regions. Current study indicated significant differences in the morphophysiological and phytochemical characteristics of D. anethifolia populations collected from 20 locations in Sistan and Baluchestan Province, Iran. The highest value of plant height and the number of lateral stems, node per plant, umbellate per umbel, seeds per umbellate and the roots fresh and dry weight were related to the location with relatively high rainfall (130-161 mm) and low altitude (up to 1165 m) compared with others. Based on the essential oil components, D. anethifolia populations were divided into five different chemotypes. Chemotypes I, II and III were characterized by high amounts of methyl chavicol, chrysanthenyl acetate and decanal, respectively. Moreover, the populations with high amounts of decanal, anethole and dodecanal were placed in chemotype IV. Chemotype V was attributed to the Naserabad population with 1-decanol as the major compound.
