- W2365724908 abstract "Objective: The chemical components of the essential oil in the Cinnamomum cassia Presl from different growth years were analyzed by GC-MS. Method: The essential oil was extracted from Cinnamomum cassia Presl by steam distillation, the components were analyzed with different kinds of capillary columns, the amount of the components from the essential oil were determinated by normalization method. The components separated were identified by GC-MS. Chromatographic conditions were; Capillary column SE-30(15 m×0.2 mm×0. 33 mm);column temperature 70℃ (1 min)8℃·min~(-1)→250℃(5 min); split injection, split ratio 30: 1; injector temperature 250℃. Mass spectrometer conditions were; ionization mode: EI, electron energy 70 eV, interface temperature 280℃, ion source temperature 200℃,quadropole temperature 100℃,mass scan range;29-450AMU,solvent delay 2. 0 min. Results:49 components constituting 95% of the total essential oil were separated and identified. Their total ion chromatograms(TIC) are similar,but there is a little difference in the TIC and the relative percentage contents. Their similar components may be used in identification of Cinnamomum cassia Presl. Conclusion:The method is reliable, stable and reproducible, this method can be applied to the analysis of the essential oil components extracted from Chinese traditional medicine." @default.
