title: Essential oils chemical composition, antioxidant activities and total phenols of Astrodaucus persicus.
abstract: OBJECTIVE
  Astrodaucus persicus, Apiaceae, is used as vegetable or food additive in some parts of Iran. The essential oils of different parts of Astrodaucus persicus from Kordestan province were analyzed for the first time and compared with other regions. In this study, antioxidant activities and total phenols determination of aerial parts essential oils and root fractions of A. persicus were investigated.
  
  
  METHODS
  The essential oils were obtained by hydro-distillation from flowers/fruits, leaves/stems, ripe fruits and roots of plant and analyzed by GC-MS. Crude root extract was fractionated with hexane, chloroform, ethyl acetate and methanol. Antioxidant activities by DPPH and FRAP methods and total phenols by Folin-ciocalteu assay were measured.
  
  
  RESULTS
  The abundant compounds of flowers/fruits blue essential oil were α-thujene, β-pinene and α-pinene. The predominant components of blue leaves/stems essential oil were α-thujene, α-pinene and α-fenchene. The major volatiles of ripe fruits blue essential oil were β-pinene, α-thujene and α-pinene. The chief compounds of root yellow essential oil were trans-caryophyllene, bicycogermacrene and germacrene-D. Total root extract and ethyl acetate fraction showed potent antioxidant activities and high amount of total phenols in comparison to other samples. Among volatile oils, the flowers/fruits essential oil showed potent reducing capacity.
  
  
  CONCLUSIONS
  The major compounds of aerial parts essential oils were hydrocarbon monoterpenes while the chief percentage of roots essential oil constituents were hydrocarbon sesquiterpenes. α-Eudesmol and β-eudesmol were identified as responsible for creation of blue color in aerial parts essential oils. A. persicus was known as a potent antioxidant among Apiaceae.
