Citrus fruits are one of the most common fruit species in the world. Bergamot is one of the important species and used extensively in essential oil production. As in other citrus species, the composition of bergamot essential oil may vary depending on many factors such as harvest time, growing conditions, production method etc. In this study, the effect of harvest times on the essential oil content and the composition of bergamot peel were investigated. The essential oil content of the samples was determined by hydrodistillation method in the Clevenger apparatus and the essential oil composition was determined by chromatographic method with GC-MS/FID apparatus. Bergamot peel essential oil content and composition were varied according to the harvest times. Essential oil content of the samples was ranged from 2.11% to 2.99% with respect to harvesting times. Totally, 14 components were determined in these essential oil samples. Limonene, linalool and lineally acetate were main components and their ratios were determined as 46.20-46.98%, 13.42-20.22% and 12.20-15.91% respectively. It is widely used in the production of essential oil. Results showed that harvesting times for bergamot has important effect on essential oil content and composition.
