Abstract:
Flos magnoliae volatile oil was extracted by steam distillation and simultaneous distillation and extraction, and then analzed using gas chromatography-mass spectrometry (GC-MS) combined with chemical component determination and comparative analysis. Results indicated that there were 30 volatile oils including rose oxide, terpinyl acetate, bornyl acetate extracted by steam distillation while 30 volatile oils including terpinolene, estragole, 1-hydroxy-1,7-dimethyl-4-isopropyl-2,7-ring decyl diene extracted by simultaneous distillation. There were 28 volatile oils were mutual and firpene, beta pinene, eucalyptol, linalool, l-camphor, alpha terpineol, alpha caryophyllene, (E)-beta acacia ene, geraniolene, cadinene, alpha burt orange tomato alcohol, farnesol with high content. The color and average yield of volatile oil extracted by steam distillation and simultaneous distillation were pale yellow and 1.3% and 1.5% respectively. These results showed that distillation of volatile oil aroma quality and yield was better than those obtained by simultaneous distillation.
