Abstract

The volatile components of clary sage (Salvia sclarea L.) oil were identified by gas chromatography-Fourier transform infrared spectroscopy (GC/FTIR) and gas chromatography-mass spectrometry (GC/MS). The application of GC/FTIR in analysis of essential oil was mainly discussed. The accuracy of qualitative analysis for essential oil was improved by such technique asthe reconstruction of different spectra regions Gram-Schmidt Fourier transforms infrared spectroscopy, and the application of subtracting of Fourier transforms infrared spectroscopy, and the mass spectrometry.

摘要

通过气相色谱-傅里叶变换红外光谱联用仪（GC/FTIR）和气相色谱-质谱联用仪（GC/MS）对鼠尾草（Salvia sclarea L.）油的挥发性成分进行了鉴定。主要讨论了GC/FTIR在精油分析中的应用。通过不同光谱区域的Gram-Schmidt傅里叶变换红外光谱重建、傅里叶变换红外光谱减法以及质谱等技术提高了精油定性分析的准确性。
