Abstract
The genus Anthemis L. belongs to the family Asteraceae, is the second-largest genus in the Compositae family, consists of 39 annual and perennial species distributed all over Iran. According to literature, this species was not the subject of research up to now and therefore its chemical composition is not well known. In this research six samples of Anthemis austroiranica were collected from Hormozgan province, in 2019. The specimen is deposited in the Central Herbarium of the Research Institute of Forests and Rangelands. The volatile constituents of A. austroiranica were isolated by water distillation (Clevenger apparatus) and analyzed by GC and GC/MS. The major components of the aerial partof samples collected from Bandar-e-Abass, Geno Mountain, altitude 2200 meters, were geranyl benzoate 17.94%, γ-eudesmol 16.33%, phenyl ethyl hexanoate 15.33% and n-heptadecane 14.84%. The major components of the aerial part of the second samples from Bandar-e-Abbas, Tang-e-Zagh, altitude of 1000 meters, were linoleic acid 25.24%, geranyl benzoate 23.66%, 7-hydroxy coumarin 10.37%. The major components of the aerial part of the third sample from Bandar-e-Abbas, Geno mountain, altitude 1385 meters, were geranyl benzoate 28.68%, 7-hydroxy coumarin 21.10%, (E)-nuciferol 7.66%. The major components of the aerial part of the fourth sample from Bastak, altitude of 450 meters, were hexadecanoic acid 31.17%, 7-hydroxy coumarin 8.39%, and phenyl ethyl hexanoate 7.44%.The major components of the aerial part of the fifth sample from Bandar-e-Abbas, Geno Mountain, altitude 1600 meters, were geranyl benzoate 24.35%, γ-eudesmol 15.50%, 7-hydroxy coumarin 7.65%. The major components of the aerial part of the last sixth samples from Hajiabad, Sirmand, Tel Mara, altitude 112 meters, were nonanal, dimethyl acetal 33.08%, hexadecanoic acid 6.16%, phenyl ethyl hexanoate 4.01%. Differences in the chemical composition of essential oils of A. austroiranica six regions can be due to differences in altitude in Geno Mountain and its distribution in Hormozgan province, as well as soil type and genetic issues.This research is performed on A. austroiranica, endemic species for the first time in Iran.
