Abstract:
OBJECTIVETo establish the quality standard of extracts from Rhizoma Zingiberis by supercritical CO2 fluid extraction.
METHODThe extracts were identified by TLC. The total phenols and the 6-gingerol were determined by dual-wavelength UV spectrophotometry and HPLC separately.
RESULTThe 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%).
CONCLUSIONThe method is convenient for a good resolution and can be used for the quality control of extracts from Rhizoma Zingiberis.
