Abstract

 

The fruits and leaves of Citrus nobilis Lourvar deliciosa Swingle were collected from south of Iran and their essential oils were analysed by gas chromatography-mass spectrophotometry (GC-MS). The oil yields of the fresh peel and leaves obtained separately by hydrodistillation were 1.2 and 0.2% (V/W), respectively. 17 components accounting for 99.2% of the peel oil and 34 components accounting for 98.5% of the leaf oil were identified. The main classes of compounds were found to be monoterpenes [monoterpene hydrocarbons (96.0%) and monoterpene alcohols (1.8%)] in the peel oil and monoterpenes [monoterpene hydrocarbons (47.6%), monoterpene alcohols (36.9%)] and sesquiterpenes [sesquiterpene hydrocarbons (2.9%) and sesquiterpene alcohols (3.7%)] in the leaf oil. The major constituent of the peel oil were limonene (87.8%) and γ-terpinene (6.1%), while the major constituents of the leaf oil were linalool (32.8%), sabinene (28.8), (E)-β-ocimene (6.2%) and limonene (5.2%).
