The MicroDistiller (Eppendorf), enables the distillation of aromatic material even in very small quantities. Using the simple microdistillation technique, minute amounts of Cyclotrichium leucotrichum (Stapf ex Rech. fil.) Leblebici and C. stamineum (Boiss. and Hohen.) Manden. and Scheng. were investigated for their volatiles by GC/MS. The main constituents were identified as beta-caryophyllene (14%), camphor (12%), and p-menth-3-en-8-ol (11%) for C. leucotrichum, and pinocamphone (33%), isopinocamphone (13%), and myrtenyl acetate (9%)for C. stamineum.
