Abstract
Mandarin (Citrus reticulata Blanco) and bergamot (Citrus bergamia Risso et Poit.) leaf oils were obtained from mandarin and bergamot leaves by steam distillation. The oils were analyzed by high-resolution gas chromatography (HRGC) and high-resolution gas chromatography/mass spectrometry (HRGC/MS). In total, 42 and 50 components were identifed in mandarin and bergamot leaf oils, respectively. Mandarin leaf oil showed a high content of monoter-pene hydrocarbons (62.6%), with sabinene (42.5%) and γ-terpinene (3.8%) being the major components. Bergamot leaf oil was characterized by a higher content of oxygenated compounds (90.4%), of which linalyl acetate (49.6%) and linalool (22.4%) were the major ones. It contained lower amounts of monoterpene hydrocarbons (8.1%) than the mandarin leaf oil.
