| 摘 要： | 目的采用HPLC法建立荷叶药材的指纹图谱。方法 Ultimate XB-C18色谱柱(4.6 mm×250 mm,5μm),流动相为0.1%甲酸+0.2%三乙胺溶液(A)-乙腈(B)进行梯度洗脱,检测波长254 nm,体积流量1.0 mL.min-1,柱温35℃。结果建立了荷叶的HPLC-UV的指纹图谱,指定出11个共有指纹峰,共指认3个共有峰的结构并对不同产地和不同采收时期荷叶的相似度进行了比较。结论本方法操作简便,快速,重现性好,为荷叶的鉴别和质量控制提供有效依据。

| Abstract: | Objective To develop a chromatographic fingerprinting method for the quality evaluation of Folium Nelumbinis using HPLC-UV.Methods Ultimate XB-C18 column（4.6 mm × 250 mm,5 μm） was used with acetonitrile-water（0.1% formic acid and 0.2% triethylamine） as the mobile phase at 35 ℃.A well-designed gradient elution program was used.The UV wavelength was 254 nm,with the flow rate of 1 mL·min-1.Results High-quality chromatographic fingerprint of Folium Nelumbinis was obtained.A total of 11 common fingerprint peaks were detected and the structures of 3 were identified.Samples from different origins were compared and so were samples with different harvest time.Conclusion The method is characterized with simple operation procedure and good repeatability,indicating this method can be effectively used for the identification and quality control of Folium Nelumbinis. |
