Abstract: The determination of the components from Herba cistanches, a kind of Chinese medicine was carried oul by the analytical supercritical fluid extraction (SFE), followed by GC/ MS. The main factors affecting the extraction efficiency, including the use of modifier, are discussed. It has been demonstrated that the analytical SFE method has more advantages over the conventional techniques, and will be effectively used in the composition investigation of Chinese medicines.

Key words: Supercritical fluid extraction, GC/MS, Chinese medicine, Herba cistanches
