目的 建立一种西红花Crocus sativus特征图谱分析方法,并用以鉴别西红花中掺假栀子Gardenia jasminoides。方法 采用HPLC法,色谱柱为ZorBax XDB-C₁₈(250 mm×4.6 mm,5 μm),流动相为0.5%醋酸水溶液-0.5%醋酸甲醇溶液梯度洗脱,检测波长为254 nm,分析时间为45 min,体积流量为1.0 mL/min。结果 通过多批样品的检测,共标出8个特征峰,建立的分析方法有较好的重复性,能够显著区分西红花和栀子。结论 方法稳定、可靠、简便,为西红花质量控制和真伪鉴别提供参考。

Objective To establish the method for the specific chromatograms analysis of Crocus sativus, so as to distinguish the active constituents between saffron and gardenia. Methods HPLC with ZorBax XDB-C₁₈ column was used, the mobile phase was a linear gradient of methanol containing 0.5% acetic acid and water containing 0.5% acetic acid in 45 min, the detection wavelength was set at 254 nm and the flow-rate was 1.0 mL/min. Results Multi batches of samples were analyzed to establish the specific chromatograms. Eight marked peaks were separated. The methodological evaluation showed that the method had a good repeatability. The active constituents between saffron and gardenia could be significantly distinguished by this method. Conclusion The method is simple, rapid, and accurate with good reproducibility and can be used for the quality control and identification of C. sativus.
