【Abstract】 Objective: To explore the preparation process for Tibetan medicine Anshen Pills. Methods: Comparing the preparation process of Tibetan medicine extracted by SFE CO 2 with that extracted by pertroleum ether and analyzing chemical components of their extracts by GC/MS. Results: The method of SFE CO 2 is superior to extractive method by pertroleum ether. The former has higher extraction ratio and shorter extraction time without residues of chemical solvent. Conclusion: The process of SFE CO 2 is suitable for the preparation of Tibetan medicine Anshen Pills.更多还原
