Study on Chemical Compositions of 12 Volatile Oils from Bergamots

Abstract

Abstract: Volatile oils of 12 representative oil samples of Citrus medica L.var. Sarcodactylis (Noot) Swingles were systematically studied. The bergamots slurries were extracted by steam distillation to get volatile oils, which were analyzed on GS/MS and elucidated by the Nist2.0 MS data. Constituents of oils were analyzed qualitatively and quantitatively. Twenty-seven kinds of chemical compositions were obtained. Among them the majority were limonene and γ-terpinene. Of all the bergamots studied, number X gives the highest volatile oil content (1.49%). They all have the same constituents with limonene and γ-terpinene as the main component. But the contents of constituents were different.

Key words: bergamot, volatile oils, GC/MS, components analysis
