Study on the HPLC Fingerprints of Glycyrrhiza uralensis Fisch.Produced in Inner Mongolia / 中药新药与临床药理

ABSTRACT

Objective To develop a HPLC fingerprints of Glycyrrhiza uralensis Fisch.in Inner Mongolia.Methods The RP-HPLC method was adopted on Phenomenex C18(4.6?250 mm,5 ?m)analytical column by gradient elution with acetonitrile and acetic acid buffer solution as mobile phase.The gradient wavelength data acquisition was employed.The analysis time was 60 minutes and the flow rate was 1 mL/min.Results The HPLC standard fingerprints chromatography of Glycyrrhiza uralensis Fisch.consists of 10 common characteristic peaks.The results of method validation accorded with the technical standard of fingerprints.Conclusion This method is stable,accurate,reliable,and can provide a scientific basis for the quality control of Glycyrrhiza uralensis Fisch..
