Main constituents of commercial C.scariosus rhizomes volatile oil were α-copaene (4.3%), cyperene (14.1%), rotundene (6.1%), caryophyllene oxide (3.5%), aristol-9-en-8-one (3.8%), mustakone (4.6%), cyperotundone (7.6%), and α-cyperone (3.0%).

Of the 21 nitrogen components reported from the essential oil of Cyperus scariosus, epi-guaipyridine (32 mg/kg), guaia-9,11-dienpyridine (9 mg/kg), and cananodine (10 mg/kg) were the most abundant. A new ketone with a significant woody ambery odor, cyperen-8-one, could also be isolated. „Rotundone was found to have the highest odor-activity value of the measured compounds and, together with the other ketones, contributes to the woody-amber character of cypriol oil.“
