[Study on ingredients of essential oils of Curcuma wenyujin extracted by supercritical-CO2 fluid extraction and steam distillation].
OBJECTIVE
To compare the ingredients of essential oils of Curcuma wenyujin extracted by supercritical-CO2 fluid extraction and by steam distillation.


METHODS
GC-MS was applied in this experiment.


RESULTS
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.


CONCLUSIONS
Supercritical-CO2 fluid extraction is better than steam distillation in extraction time, power consumption, recovery and purity.
