摘要: 采用中药指纹图谱技术建立马钱子(Strychni semen)药材的HPLC指纹图谱,为马钱子质量控制提供新方法。以甲醇-水-浓盐酸(50∶50∶1),超声提取30 min,制备供试品溶液;以乙腈∶水(0.2%甲酸)为流动相,梯度洗脱;分析时间60 min;检测波长为254 nm;柱温30 ℃;流速1.0 mL/min。结果表明,以马钱子碱为参照物,确定了马钱子指纹图谱中6个共有峰。该方法精密度、稳定性、重现性试验RSD均小于3%;采用相似度作为指纹图谱的评判参数,10批马钱子的HPLC色谱图与对照指纹图谱之间相似度均大于0.9。

Abstract: To establish the HPLC fingerprint of Strychni semen by TCM fingerprint technology, and provide a new method for the quality control of Strychni semen. The extraction methods was ultrasonic for 30 min by methanol-H2O-HCl (50∶50∶1). The mobile phase was acetonitrile-H2O (0.2% formic acid). The gradient elution mode was applied in chromatographic separation; the analysis time was 60 min; the detection wavelength was 254 nm; the column temperature was 30 ℃; the flow rate was 1.0 mL/min. The results showed that with brucine as the reference, six common peaks in the fingerprint of Strychni semen were determined. The RSD of precision, stability and reproducibility of the method was less than 3%. Using similarity as the evaluation parameter of fingerprint, the similarity between the chromatogram and the control fingerprint of 10 batches of Strychni semen was greater than 0.9.
