| Abstract: | AIM To establish an HPLC/ESI-MS method for quickly identifying chemical constituents in extracts of Glycyrrhizae Radix et Rhizoma.METHODS The separation was performed on Kromasil C18 column(250 mm×4.6 mm,5 μm) with a mobile phase of 0.05% formic acid aqueous solution(A) and acetonitrile(B).The flow rate was maintained at 1.0 mL/min and detection wavelength was set at 195~400 nm.The samples were analyzed in both positive and negative modes.RESULTS Fourteen flavonoids,eight saponins and coumarins in extracts of Glycyrrhizae Radix et Rhizoma could be separated in one run.CONCLUSION The new method is accurate and rapid.It can be used to identify the main chemical constituents in extracts of Glycyrrhizae Radix et Rhizoma and it is suitable for quality control of Glycyrrhizae Radix et Rhizoma. |
