Abstract

The invention discloses a detection method for fingerprints of Ligustrum lucidum licorice juice, the method comprises the following steps: Step 1, preparation of a test solution of Ligustrum lucidum licorice juice; step 2, preparation of a mixed reference solution; step 3, Precisely draw the quantitative test sample and reference solution into the liquid chromatograph, and record the chromatogram; step 4, export the fingerprint instrument of Ligustrum lucidum licorice juice, and import it into the Chinese medicine chromatographic fingerprint similarity evaluation system, select different The chromatographic peaks that exist in the chromatograms of batches of licorice juice-burned Ligustrum lucidum are used as common peaks, and the control fingerprints of licorice juice-burned Ligustrum lucidum are generated by the average value calculation method, and the relative retention time and relative peak area of ​​each common peak are calculated. . The fingerprints of the Ligustrum lucidum roasted with licorice juice studied by the present invention can comprehensively and objectively evaluate the quality of the Ligustrum lucidum roasted with licorice juice. The detection method provided by the invention has the advantages of simple method, high accuracy, good repeatability, high precision and the like.

Description
