裸花紫珠药材的指纹图谱研究
【摘 要】建立海南裸花紫珠HPLC指纹图谱,为其真伪鉴别和质量控制提供依据。方法: HPLC色谱条件: Thermo Acclaim TM 120 C18 5μm 120A(250 mm×4.60mm)色谱柱,以乙腈-0.1%甲酸为流动相梯度洗脱,流速1.0ml/min,柱温:35℃,检测波长332nm,进样量:10μl。结果:以16批裸花紫珠样品的11个峰为共有峰评价指标,建立裸花紫珠的HPLC指纹图谱测定方法,相似度较好。结论:该方法可用于该药材的鉴别及质量控制。【关键词】 裸花紫珠;指纹图谱
【Abstract】Objective:To establish HPLC fingerprint method for the quality evaluation and discrimination of Callicarpa nudiflora. Methods : The chromatographic fingerprint of 16 samples was determined by injecting 10 μl of the sample solution each time om a reversed phase Thermo Acclaim TM 120 C18 column with the gradient elution solvent system composed of 0.1% Formic acid solution and acetonitrile . The flow rate was 1.0 ml/min ......
