Hongyan Zhao

Abstract

Objective To study the chemical constituents of the essential oils from Viburnum fordiae Hance. Methods The essential oils were extracted by steam distillation(SD) and supercritical carbon dioxide extraction(SFE),and then the constituents were separated and identified by GC-MS. Results 77 compounds were isolated and 40 compounds were identified by SD that composed about 90.07 % of the total essential oils;And 67 compounds were isolated and 42 compounds were identified by SFE that composed about 86.50% of the total essential oils. Conclusion There are some differences in the principal chemical constituents and contents of the essential oil extracted by SD and SFE.
