The genus Anthemis L. is the second largest genus in the Compositae family, which consists of 39 annual and perennial species scattered throughout Iran. In this research, a species of Anthemis lorestanica Iranshahr was collected from two regions in Isfahan province, namely Makdin region (sample 1) and Badum Valley region (sample 2) in 2017. The samples were identified in the herbarium of the Research Institute of Forests and Pastures in the Department of Botany. The essential oils were extracted from its flowers and leaves by water distillation method (Klenger method). Then the essential oil samples were measured and identified by gas chromatography (GC) and gas chromatography connected to mass spectrometer (GC/MS). The amount of essential oil in sample 1 was 0.12% for flower and 0.08% for leaf. Major compounds in the flower consisted of methyl decanoate (18.6%), α-cadinol (11.1%), and n-tricosan (9.1%). Major compounds in leaves were neryl acetate (13.4%), α-cadinol (12.9%), and dihydro eudesmol (8.5%). Essential oil contents of sample 2 were 0.2% for flower and 0.08% for leaf. The main flower compounds included spathulenol (68.8%), dehydro-aromadendrane (5.2%), and oplopanone (3%). The main compounds of the leaves were oplopanone (12.3%), 1-icocen (11.5%), and dihydro eudesmol (10.9%).
