چکیده انگلیسی
Supercritical fluid chromatography hyphenated with high resolution mass spectrometry (SFC-HRMS) was developed for fingerprint analysis of different flower absolutes commonly used in cosmetics field, especially in perfumes. Supercritical fluid chromatography-atmospheric pressure photoionization-high resolution mass spectrometry (SFC-APPI-HRMS) technique was employed to identify the components of the fingerprint. The samples were separated with a porous graphitic carbon (PGC) Hypercarb⢠column (100â¯mmâ¯Ãâ¯2.1â¯mm, 3â¯Î¼m) by gradient elution using supercritical CO2 and ethanol (0.0-20.0â¯min (2-30% B), 20.0-25.0â¯min (30% B), 25.0-26.0â¯min (30-2% B) and 26.0-30.0â¯min (2% B)) as mobile phase at a flow rate of 1.5â¯mL/min. In order to compare the SFC fingerprints between five different flower absolutes: Jasminum grandiflorum absolutes, Jasminum sambac absolutes, Narcissus jonquilla absolutes, Narcissus poeticus absolutes, Lavandula angustifolia absolutes from different suppliers and batches, the chemometric procedure including principal component analysis (PCA) was applied to classify the samples according to their genus and their species. Consistent results were obtained to show that samples could be successfully discriminated.
