Abstract:
Objective To establish a combined quality evaluation model of fingerprint and quantitative analysis of multi-components with a single-marker (QAMS) to analyze the total flavonoids from licorice residue by the chemical conversion method; To provide technical support for quality control in production. Methods Total flavonoids of breaking cell wall and enriching were taken as the object of study to establish fingerprint. With liquiritin as internal reference, the relative correction factors of isoliquiritin, glycyrrhizin, isoliquiritigenin and glycyrrhizic acid were established respectively, and the contents were determined. Meanwhile, the calculated values were compared with the measured value by external standard method to verify the practicability and stability of QAMS. Results The HPLC fingerprint of total flavonoids from licorice residue was established. 11 common peaks were identified, and 5 common peaks were identified, and the similarity of the 10 extracts was >0.99; the relative error between the calculated results of QAMS and the measured values of the external standard method was <4%; the RSD of relative correction factor calculated by the multiple concentration method was <2%. Conclusion The method is accurate, reliable, specific, and stable, with good repeatability, which can be used for the quality control of total flavonoids from licorice residue.
