Composition of Turkish mandarin and bergamot leaf oils

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 identified in mandarin and bergamot leaf oils, respectively. Mandarin leaf oil showed a high content of monoterpene hydrocarbons (62.6%), with sabinene (42.5%) and gamma-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.
