RESUMO
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 (130-161â mm) and low altitude (up to 1165â 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.

The antioxidant activities of crude extract fractions using Hexane, Chloroform, Ethyl Acetate, Butanol and Water of Clematis orientalis and Clematis ispahanica were investigated. 1,1-diphenyl-2-picryl-hydrazyl (DPPH) assay and the ferric reducing/antioxidant potential (FRAP) were used to evaluate the antioxidant capacity. The total phenolics were found to be 4.37-9.38 and 1.32-11.37 mg gallic acid equivalents (GAE)/g in different fractions for C. orientalis and C. ispahanica, respectively. The ethyl acetate fraction of C. orientalis and chloroform fraction of C. ispahanica showed the highest DPPH and FRAP activities at a concentration of 300 µg/mL. The predominant phenolic compounds identified by HPLC in C. orientalis were Resorcinol (603.5 µg/g DW) in chloroform fraction and Ellagic acid (811.7 µg/g DW) in chloroform fraction of C. ispahanica.
