摘要 目的建立砂蓝刺头Echinops gmelini的质量控制方法。方法采用薄层色谱法,以三氯甲烷-醋酸乙酯-甲醇-甲酸(6∶1∶1∶0.8)为展开剂对砂蓝刺头花中1-甲基-4-甲氧基-8-(β-D-葡萄吡喃型糖苷)-2(1H)-喹啉酮(MMQ)进行定性鉴别;建立砂蓝刺头HPLC指纹图谱,并对MMQ的含量测定方法进行研究。结果建立的TLC方法对照品斑点清晰,分离度好;建立的指纹图谱分析方法能够区分砂蓝刺头与近源植物,标定了8个特征峰,并指认出其中4个成分。定量方法测定结果显示MMQ在2.024~151.800μg/mL呈良好线性关系,平均加样回收率为101.54%,RSD为1.46%。7批样品中MMQ的质量分数为0.13%~0.53%。结论建立的质量控制方法科学、可靠,可为砂蓝刺头质量标准的建立提供实验依据。 Objective To establish the quality control method for of Echinops gmelini. Methods Thin layer chromatography(TLC) method was used for quanlitative analysis of the 1-methyl-4-methoxy-8-(β-D-glucopyranoside)-2(1H)-quinolinone(MMQ) with a mixture of trichloromethane-ethyl acetate-methanol-formic acid(6∶1∶1∶0.8) as the developing solvent. The HPLC fingerprint of the capitulum of E. gmelini and the determination of MMQ were conducted by HPLC. Results The spots on TLC plate were clear, well-separated and specific without any interference. The linear range of calibration curve was 2.024—151.800 μg/mL, and the average recovery was 101.5% with RSD of 1.46%, which can be used for the quality control of E. gmelini. The contents of MMQ in seven batches of E. gmelini were 0.13%—0.53%. Conclusion The qualitative and quantitative determination method is scientific and reliable, which can provide an experimental basis for the establishment of the quality standard of E. gmelini.
