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