| Abstract: | Objective To determine the contents of the protocatechuic acid in the different prepared slices of Rhizoma Cibotii for evaluation of the quality of different processed products of Rhizoma Cibotii.Methods The HPLC separation was performed with Hypersil ODS C18(4.6 mm×100 mm,5 μm) column,a mixture acetonitrile and 1% glacial acetic acid(5∶95)solution as the mobile phase and a flow rate of 1.0 mL/min.The detection wavelength was 260 nm and the column temperature was 25 ℃.Results The content of protocatechuic acid in the prepared slices,hot fried and steamed Rhizoma Cibotii were 0.028%,0.040% and 0.051% respectively.Conclusion The content of protocatechuic acid in the steamed Rhizoma Cibotii is the highest. |
