Abstract:

Using solid-phase micro extraction-gas chromatography-mass spectrometry (SPME-GC-MS) technique, a rapid, simple and fully automated procedure was developed for the identification of essential oil from Tianmeng Mountain Imperial Chrysanthemum. The relative mass fraction of each component was calculated by the normalization method of chromatographic peak area. Fifty seven chemical components were identified in total, accounting for 82.448% of the total GC peak area of essential oil. The principal chemical constituents and their relative mass fractions were as follows: Eucalyptol (12.44%), D-Camphor(9.209%), (1S)-(-)-α-Pinene (8.597%), L(-)-Borneol (6.172%), β-Phellandrene(5.642%), L-Bornyl acetate (4.861%).
