新疆一枝蒿药材双波长HPLC指纹图谱的研究

HPLC dual-wavelength fingerprint of Artemisia rupestris L.

  • 摘要: 建立新疆一枝蒿药材双波长HPLC指纹图谱的测定方法,为药材质量标准提升提供科学依据。采用HPLC法,Zorbax SB-C18色谱柱(4.6 mm×250 mm,5 μm),柱温32 ℃;流动相:甲醇-0.2%甲酸水梯度洗脱;流速1.0 mL/min;检测器:DAD检测波长245和325 nm;进样量20 μL。建立了新疆一枝蒿的HPLC指纹图谱,分别在245和325 nm处确定了7个和8个共有峰,并确证了槲皮素、绿原酸、木犀草素、芹菜素、蔓荆子素5个色谱峰,9批次新疆一枝蒿药材与生成对照指纹图谱的相似度大于0.9。首次建立了新疆一枝蒿药材双波长HPLC指纹图谱,所建立的指纹图谱测定方法精密度、稳定性和重复性良好,可用于新疆一枝蒿药材的鉴别和质量控制。

     

    Abstract: To establish HPLC dual-wavelength fingerprint of Artemisia rupestris L. , and provide a scientific basis for the improvement of its quality specifications. The separation was performed on an Agilent Zorbax SB-C18(4. 6 mm×250 mm, 5 μm)column maintained at 32 ℃, with methanol-0. 2% formic acid-water gradient elution at flow rate of 1. 0 mL/min and the UV detection wavelength at both 245 and 325 nm. The sample injection volume was 20 μL. The fingerprint of Artemisia rupestris L. was established. 7 and 8 common peaks were found, respectively, of which 5 common peaks were identified, and the similarity among 9 batches of Artemisia rupestris L. and the fingerprints of control was over 0. 9. The HPLC dual-wavelength fingerprint of Artemisia rupestris L. was established for the first time, providing a new scientific basis for its identification and quality control.
