摘要: AbstractThis study aimed to develop a rapid and accurate analytical method for discriminating three lavender varieties (French blue, H-701, C-197(2)) that could not be easily distinguished by volatile compounds. A total of 22 samples from were analyzed static headspace (HS) coupled with gas chromatography-mass spectrometry (GC-MS). The experimental parameters including equilibrium time, temperature water addition investigated. optimal conditions 0.5 g sample as follows: an time 20 min, 90°C volume 2 mL. Using the proposed method, 26 compounds in identified. results further processed discriminative cluster analysis (CA) principal component (PCA) detect clustering formation establish relationships between their components. These clearly differentiated a...
