Composition of Cyperus luzulae rhizome essential oil from Peru

Cyperus luzulae (L.) Rottb. ex Retz is an understudied species within the Cyperus genus. To the best of the authors' knowledge, the essential oil from this species has never been fully characterized. Essential oil obtained through steam distillation of C. luzulae rhizomes was analyzed to establish the chemical profile by GC/FID and GC/MS. The chemical profile revealed a high content of sesquiterpene hydrocarbons (36.9%) and oxygenated sesquiterpenes (34.9%). The major compounds of the oil were caryophyllene oxide (23.5%), -selinene (12.9%), and -copaene (8.3%). These results provide fundamental data for future investigations into the ethnobotanical and pharmacological uses of this species, broadening the scope of knowledge on the Cyperus genus and its potential applications.
