This study was aimed to examine scent compounds of its new extraction products and to compare the essential oil efficiency and quality of hydrodistillation in two H. italicum [Corsica-France (CF) and Čitluk-Bosnia Herzegovina (CBH)] ecotypes grown for the first time in Türkiye. The floral scent components of immortelle flowers were determined by solid phase microextraction (HS-SPME/GC–MS) method. While ß-himachalene and α-pinene were the main floral compounds of the fresh flowers for the CBH, neryl acetate and 1,8-cineole for the CF. The essential oil content of the CF and CBH was 0.38 and 0.15%, respectively. The essential oil compounds of the CBH consisted of ar-curcumene (25.57%), α-pinene (13.66%) and neryl acetate (12.90%), and the CF consisted of neryl acetate (56.08%) and 1,8-cineole (7.60%). The highest concrete (1.30%) and absolute (76.5%) yields were obtained from the CF. As with the essential oil, the main component of the CF concrete is neryl acetate (52.46%) and the CBH concrete is ar-curcumene (16.96%). But the hydrocarbons were higher in the concretes than in the essential oil. While obtaining the absolute from the concrete, the hydrocarbon compounds were separated and the volatile components of both absolutes showed similarity to the essential oil. This similarity increases the potential of preferring the lower cost absolute instead of the high cost immortelle oil. Considering the potential to be used directly in perfume and cosmetic formulations when the undesirable properties of absolutes (such as color and waxy structures) are removed, it is expected that the findings of the present study will contribute to this.
