Analysis of Chemical Constituents and E-scent of Rose Oil

In order to identify rose oil of different grades, the chemical constituents in high and medium grades of rose oil were qualitatively and quantitatively analyzed by GC/MS, 63 and 72 constituents were respectively identified. The two kinds of rose oil and one unknown sample were scanned with an e-nose device. The results showed that the e-nose device could be used in grade distinction of rose oil.
