Abstract:
Objective: To compare supercritical CO 2 fluid extraction(SFE CO 2) with steam distillation(SD) in the chemical constituents and content of essential oil from Forsythia Suspensa. Method: GC MS combination was adopted. Results: Both the two methods shared the same main components as ? pinene, ? pinene and sabinene. Benzene methanol,4 [1 methylethyl] and Benzene methanol,2 [4 methylethyl] were extracted exclusively by SFE CO 2, Among two methods there is a good deal of similarity all the other components extracted. Furthermore, sabinene、transpinocarveol and shorten were the first obtained from the plant. Conclusion: The SFE CO 2 was superior to SD in raising yield and reducing extractive time. It is a good method in extracting the essential oils from Forsythia Suspensa.
