金菊五花茶颗粒的质量标准研究

Study on Quality Standard of Jinju Wuhuacha Grain

目的提高金菊五花茶颗粒的质量标准。方法采用薄层色谱法鉴别木棉花、葛花、山银花;用HPLC测定槐花中芦丁的含量。结果薄层色谱斑点清晰,阴性对照无干扰。HPLC线性关系良好,平均回收率为100.8%,RSD为0.78%(n=6)。结论方法简便可靠,专属性强,重现性良好,可用于金菊五花茶颗粒的质量控制。

Objective To improve the quality standard for Jinju Wuhuacha grain. Methods Kapok, lobed kudzuvine flower, and wild honeysuckle immature flower in this preparation were identified by TLC, and the rutin of sophora flower was determined by HPLC. Results The kapok, lobed kudzuvine flower, and wild honeysuckle immature flower in samples were positive in TLC. The result of HPLC had good linear behavior. The average recovery rate was 100.8% , and the RSD was 0.78% （ n = 6 ）. Conclusion These methods are simple and accurate, and can be used in the quality control of Jinju Wuhuacha grain.
