Essential oils of Helichrysum faradifani were isolated from fresh or dry plant parts by steam distillation with yields from 0.1-0.8%. Analysis of the oils by GC and GUMS enabled the identification of 49 components, of which alpha-fenchene (trace-27.3%), beta-caryophyllene (14.8-29.2%) and P-himachalene (15.7-36.6%) were most predominant.
