摘要: 本文提出了一种测定金银花和含金银花的八种中成药中绿原酸标志物的毛细管区带电泳分析方法。所用的背景电解质为含有10 mmol·L-1磷酸盐和20 mmol·L-1硼酸盐的pH7.00的缓冲溶液,并含有5%的乙醇以提高样品的溶解度。测定的线性范围在27.7~665 μg·mL-1, 相关系数r = 0.9996。测定金银花和含金银花的八种中成药中的绿原酸可以在15分钟内完成。本分析方法简单、快速、适用面广。

Abstract: A simple, rapid and versatile capillary zone electrophoresis method was developed for the determination of chlorogenic acid as a marker in traditional Chinese medicines. The buffer solution used was a solution consisting of 10 mmol·L-1 phosphate and 20 mmol·L-1 boric acid containing 5% ethanol with the apparent pH value adjusted to 7.00. The linear calibration range was 27.7~65 μg·mL-1 (r = 0.9996). The contents of chlorogenic acid in Flos Lonicerae and eight Flos Lonicerae containing Chinese medicines wee easily determined within 15 min with the sameprocedure.
