ABSTRACT
OBJECTIVE: To compare the ingredients of essential oils of Curcuma wenyujin extracted by supercritical-CO2 fluid extraction and by steam distillation. METHOD: GC-MS was applied in this experiment. RESULT: The ingredients and physical and chemical properties of essential oils of C. wenyujin extracted by supercritical-CO2 fluid extraction and by steam distillation are similar. CONCLUSION: Supercritical-CO2 fluid extraction is better than steam distillation in extraction time, power consumption, recovery and purity.
