Determination of aromatic ingredients of Salvia sclarea by headspace solid phase microextraction-gas chromatography-mass spectrometry

Objective To establish a method for rapid determination of volatile aroma components in Salvia sclarea by headspace solid phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS). Methods The volatile aroma components of Xinjiang Salvia sclarea were analyzed by means of headspace solid phase microextraction-gas chromatography-mass spectrometry, and the relative content of each component was calculated by area normalization method. Results A total of 18 chemical components were identified, including Linalyl acetate (79.85%)andLinalool (8.32%).Conclusion Headspace solid phase microextraction and gas chromatography-mass spectrometry have the advantages of less sample consumption and simple pretreatment process, which is suitable for the determination of volatile aroma components in Salvia sclarea.
