ABSTRACT
<p><b>OBJECTIVE</b>To establish the quality standard of extracts from Rhizoma Zingiberis by supercritical CO2 fluid extraction.</p><p><b>METHOD</b>The extracts were identified by TLC. The total phenols and the 6-gingerol were determined by dual-wavelength UV spectrophotometry and HPLC separately.</p><p><b>RESULT</b>The recovery of total phenols was 97.7% (RSD 2.0%). The linear range of 6-gingerol is 0.20-2.0 microg, the average recovery was 97.7% (RSD 2.0%).</p><p><b>CONCLUSION</b>The method is convenient for a good resolution and can be used for the quality control of extracts from Rhizoma Zingiberis.</p>
