Investigation of Chemical Composition of Anthemis coelopoda Boiss. Essential Oil from Three Regions in Gilan Province

The genus Anthemis L. belongs to the family Asteraceae, is the second largest genus in the Compositae family, tribe Anthemideae, about ۱۳۰ species of genus Anthemis occur throughout the world consists of ۳۹ annual and perennial species distributed all over of Iran. According to literature, this species was not the subject of research up to nowtherefore its chemical composition is not well known. In this research three samples of Anthemis coelopoda . were collected from Gilan province, in the ۲۰۲۰. specimen is deposited in Central H and analyzed by GC and GC/MS. Main components from sample one Gilan: Loshan, before Hanifa Imamlower were β- calacorene ۳۵.۹%, Elemicin ۲۴.۰% and n-dodecanol ۸.۸% and in leaf were β- calacorene ۲۶.۸%, elemicin ۱۳.۹% and n-dodecanol ۱۱.۸%, and essential oil yield from flower were ۰.۰۴% and leaf were ۰.۰۳%. Main components from sample two Gilan: southwest of Rudbar, Lake ۱۱۸۱ meters high, in flower were γ- cuprenene ۱۸.۲%, n-dodecanol ۱۳.۸% and geranyl propanoate ۷.۴% and in leaf were n-dodecanol ۱۳.۵%, - terpinen-۷-al ۱۰.۸% and geranyl propanoate ۱۰.۲%, and essential oil yield from flower were ۰.۱۰% and in lead were ۰.۰۷%. Main components from sample thee Gilan: Loshan, before Hanifa Imamzadeh, near the cement mine, ۸۰۱ meters high, in flower were n-dodecanol ۱۱.۸%, - terpinen-۷-al ۹.۳% and Cumin aldehyde ۸.۸% and in leaf were n-dodecanol ۱۴.۹%, - terpinen-۷-al ۱۱.۱% and ۵-hydroxy isobornyl isobutanoate ۱۰%, and essential oil yeild from flower were ۰.۰۹% and in leaf were ۰.۰۶%. Sampling simultaneously on one day from three different areas (Samples ۱ and ۳ were collected from one area but at a great distance) their essential oils were examined for chemical composition and the results indicate different combinations and amounts in a species. This difference can be the result of differences in soil type and different plant water uptake.
