Preliminary Study on Fingerprints of Fructus Ligustri Lucidi by HPLC / 中药新药与临床药理

ABSTRACT

Objective To establish the HPLC fingerprints of Fructus Ligustri Lucidi.Methods HPLC-ELSD analysis was carried out with Lichrospher C18 column(4.6 mm ? 250 mm,5 ?m).The detector was Alltech ELSD 2000.The method was developed by gradient elution with methanol and water as the mobile phase.With oleanolic acid as the marker,sixteen batches of Fructus Ligustri Lucidi were analyzed with computer-aided similarity evaluation system.Results HPLC fingerprints of Fructus Ligustri Lucidi showed 14 characteristic peaks and the similarity of the fingerprints of 10 batches of samples was over 0.90,indicating the fingerprints being stable and repeatable.Conclusion The method is simple,accurate and with a good reproducibility,and can be used for the identification and quality control of Fructus Ligustri Lucidi.
