Abstract:
Citrus bergamia Risso. is a rare perfumery plant. Taxonomists have different views
on the taxonomy of C. bergamia. Chemical components of leaf and peel essential oils from C.
bergamia, and its close relatives, C. limon, C. aurantifolia and three varieties of C. aurantium,
were analyzed by GC and GC-MS. The analytical result shows that the chemical composi-
tions of the leaf essential oils from C. bergamia are basically the same as those from three va-
rieties of C. aurantium. Their main components are linalool (29.19-39.75% )and linalyl
acetate (24.73-30.24% )etc., and contents of other components are also similar. But their
peel essential oils are different. The peel essential oils from C. bergamia contain less limonene
(29.94%) than those from C. aurantium (92.55-94.31% ) and less beta-pinene (3.00%) and
y-terpinene(3.48% )than those from C. limon or C. aurantifolia (respectiyely 9.16% and
10.42% ) . The peel essential oils from C. bergamia contain not only as much linalool
(22.20%) and linalyl acetate (32.66%)as those in the leaf essential oils from C. aurantium,
but also as much limonene(29.94% )as that in the peel essential oils from C. limon or C.
aurantifolia . The contents of limonene are close to those of the essential oils from C.
aurantifolia.
This result shows that C. bergamia may be a natural hybrid between C.
aurantium and C. aurantifolia, as proposed by Sinclair W. B.
