Abstract

The seed of Cuminium cyminium was produced by dry farming at 4 separate planting dates (Feb. to Mar. with 10 day interval), in Kerman province (Sirch region). Then the seeds were harvested in June.
The essential oils of seeds was isolated by Clevenger apparatus to produce the oil in A=1.5%, B=3.4%, C=3.4% and D=3.1% w/w yield respectively, and analysed by GC/MS. Among thirteen indetified components, Non-oxygenated monoterpene consist 57.3, 44.7, 41.6 and 40.2 percent, and oxygenated monoterpens (aldehyde) consist 42.7, 55.3,
58.4 and 59.8 percent of the essential oil respectively. Cuminyl aldehyde and P-Mentha-1,4-dien-7-al were the major consituents in the oil. This survey revealed that the planting date has a strong influence on the quantitative and qualitative aspects of cumin oil.
