Analysis of Aroma Components in Orange Oil by GC/MS Combined with the Retention Index

Abstract:

The aroma components in orange oil were analyzed in this study by gas chromatography spectrometry（GC-MS）. Sixty compounds account for 98.69% were identified using mass spectrometry database search. The peak area normalization method was used to calculate the relative content of each component. Combining with the odor evaluation，the characteristic aroma compositions in the orange oil were identified as limonene，myrcene，linalool，decanal，α-pinene，sabinene，octanal，α-terpineol，ethyl butyrate，citronellal，nonanal，1-nonanol and so on. This study provided theoretical basis and technical support for the development and application of orange oil.
