  • Title: [Study on fingerprint of unfinished product of Nauclea injection].
    Author: Li T, Wang WJ, Hu X.
    Journal: Zhongguo Zhong Yao Za Zhi; 2005 Aug; 30(15):1156-8. PubMed ID: 16201688.
    Abstract:
    OBJECTIVE: To establish HPLC fingerprints of unfinished product of Nauclea injection. METHOD: A high performance liquid chromatography assay was developed with an Agilent-Extend C18 column, a gradient elution:water-5% acetonitrile (10 min), 5% acetonitrile-10% acetonitrile (10-60 min), 50% acetonitrile-water (60-70 min), a 0.7 mL x min(-1) flow rate, at detection wavelength, 245 nm within a 70 min total elution time. RESULT: The RSD of relative retention time and peak area of coexist peaks meet to method requirement during the investigation of precision, stability and repeatibity trials. All of the 10 batches of samples share a high similarity. CONCLUSION: This method can be used to control the quality of unfinished product of Nauclea injection.
