[Study on the volatile oil by SFE-CO, from crude and processed Rhizoma Atractylodis by GC-MS].
OBJECTIVE
To analyze the chemical constituents of the volatile oil by SFE-CO2 from Rhizoma Atractylodis and its roasted products.


METHODS
The chemical constituents of the volatile oil extracted by SFE-CO2 were separated and identified by GC-MS.


RESULTS
33 kinds of constituents were identified from Atractylodes lancea (Thunb.) DC. and its roasted products. The relative contents of 12 kinds of constituents from the processing products were descended and 7 kinds were ascended; 30 kinds of constituents were identified from Atractylodes chinensis (DC.) Koidz. and its roasted products. The relative contents of 10 kinds of constituents from the roasted products were descended and 11 kinds were ascended.


CONCLUSIONS
In the processed products, the relative contents of some low boiling point constituents are descended but some high are ascended.
