Abstract: Objective To analyse the chemical compositions and their relative content of volatile oils from fresh and dried Citrus Bergamot. Methods The microanalytical technique combining Gas Chromatography and Mass Spectrometry(GC-MS) was used for the qualitative as well as quantitative determinations of compounds from the Bergamot volatile oils. The results was compared with NIST98MS database by computer. Results More than 30 kinds of chemical composition were obtained from Bergamot volatile oils. Among them the majority were D-Limonene and (+)-2-Carene. Their relative content was 40.02%,21.35% in fresh Bergamot volatile oils and 38.63%,18.17% from dried Bergamot. Conclusion The majority chemical composition in Citrus Bergamot volatile oils were Limonene and Carene. -
