They are used in aromatherapy, cleaning (in natural cleaning products for their antimicrobial properties), natural fragrances and also as preservatives in meat and cheese industries. Essential oils obtained by hydro-distillation from flowers and seeds of cumin were investigated. Gas chromatography-mass spectrometry (GC/MS) was used for the identification of the volatile compounds. The Folin-Ciocalteu method was chosen for determination of total phenol content (TPC). The antioxidant activity of C. cyminum essential oils were assessed using 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay. Essential oil yields were 1.75% in flowers, and 3.63% in seeds. Major components of the oils were ?-terpinene (20.2%) in flowers and cumin aldehyde (36.1%) in seeds, respectively. The total phenol content of the essential oils of different parts of cumin ranged from 10.3 to 17.8 mg of GAE/g of dw. The antioxidant activity of the cumin essential oils obtained from flowers was found to be lower than synthetic antioxidant butylated hydroxytoluene (BHT).
