Oxygenated sesquiterpenes constituted the bulk of both oils (54.2% and 52.1% for the red and black types, respectively). The major components of the oil of the red type were cyperotundone (42.3%), piperitone (10.1%), β-maaliene (8.4%) and germacrone (5.3%), while the oil of the black type had an abundance of cedrol (19.0%), guaia-5-en-11-ol (14.9%) and cyperotundone (9.6%).
