狼毒药材HPLC指纹图谱研究

目的采用高效液相色谱法(HPLC)建立狼毒药材的指纹图谱。方法 2013年10月至2014年10月,使用Hypersil ODS(250mm×4.6mm,5μm)色谱柱,以乙腈-水为流动相,梯度洗脱,洗脱流速为1.0mL/min,柱温20℃,检测波长210nm,进样20μL。结果对不同来源15批狼毒药材进行了分析,标定了15个共有峰,15个共有峰相对保留时间相对标准差(RSD)≤3.7%,相对峰面积RSD≤3.6%;各色谱峰分离度较好,相似度较高,15批不同来源狼毒药材中,除了广西南宁药材料相似度为0.858,其他产地药材料相似度均在0.95以上。达到了中药指纹图谱的技术要求。结论该方法简便、准确、重现性好,可用于狼毒指纹图谱的测定及质量控制。

Study on HPLC fingerprint of radix euphorbiae fischerianae

Objective To establish fingerprint of Radix Euphorbiae Fischerianae by high performance liquid chromatography (HPLC) .Methods The samples were separated on Hypersil ODS(250 mm × 4 .6 mm ,5 μm) column with gradient mobile phase of acetic-water ,the column temperature was 20 ℃ with the flow rate of 1 .0 mL/min and UV detection wavelength was 210 nm .the sample injection was 20 μL .Results 15 samples of different origin Radix Euphorbiae Fischerianae were detected and each chroma-tographic peak was separated well with conforming to the requirements of fingerprint by calibrating the 15 peaks .15 common peak retention time RSD ,relative peak area RSD were 3 .7% ,3 .6% or less respectively ;The chromatographic peak separation degree was better ,similarity was higher ,15 batches of different sources of stellera medicinal materials ,in addition to the Guangxi nanning medi-cine material similarity was 0 .858 ,other origin medicine material similarity above 0 .95 .Have reached the technical requirements of traditional Chinese medicine (TCM ) fingerprint .Conclusion The method is accurate ,reliable ,and the HPLC fingerprint shows good repeatability ,which can be used for one of the quality control of Radix Euphorbiae Fischerianae .
