Title: Comparative essential oil composition of fennel (Foeniculum vulgare Mill.) fruits collected during different three years
Abstract: Fennel (Foeniculum vulgare Mill., Apiaceae) is a well-known aromatic and medicinal plant [1]. Essential oils obtained by hydrodistillation from fresh ripe fruits of fennel collected during three different years (2001–2003) from experimental cultures were investigated to evaluate their chemical profile related to climatic conditions. The constituents of the essential oils have been characterized using gas chromatography and mass spectroscopy analysis (GC-MS) [2]. The yield of the essential oil ranged from 2% in 2003 to 12.6% in 2002 and 11% in 2001, respectively. The main compounds in all fennel volatile oils were: t-anethole, estragole, fenchone and limonene. A discrete variation in the aromatic fraction content from 80.50% (2003) to 83.81% (2001) and 85.81% (2002) was observed. On the other hand, we noticed a significant increase of the monoterpenes level from 12.55% (2002), 13.96% (2001) to 19.29% (2003). The essential oil of fennel fruits showed a characteristic chemical profile from year to year. The content and its monoterpenes components were the most susceptible features of fennel essential oil to be affected by climatic conditions.
