摘要：The essential oils from Santalum album heartwood is known as East Indian sandalwood oil and has been approved for daily intake as food recently. In order to develop a quick authentication method for East Indian sandalwood oil, the essential oils are hydro distillated from trunks of five Santalum species (Santalum album, Santalum lanceolatum, Santalum spicatum, Santalum austrocaledonicum, and Santalum yasi) and assessed by attenuated total reflectance-Fourier transform mid-infrared spectroscopy (ATR-FTIR). The mid-red spectra obtained from essential oils from all five Santalum species are similar and assigned to chemicals with the same functional groups. Most essential oils from other four Santalum species can be discriminated from those from Santalum album by principal component analysis (PCA). In addition, the results of partial least square (PLS) models suggested the strong correlations between santalols proportions quantified by GC-MS and ATR-FTIR spectra of essential oils, which suggests that FTIR combined with chemometric analysis might be a rapid analytical technique for sandalwood oil quality assessments. ? 2019, ? 2019 Informa UK Limited, trading as Taylor & Francis Group.
