清肺止咳合剂质量标准研究

Study on Quality Standard for Qifeizhike Composition

目的:制定清肺止咳合剂质量标准。方法:采用薄层色谱法(TLC)鉴别金银花、黄芩,高效液相色谱法(HPLC)测定绿原酸的含量。结果:TLC色谱能明显检出金银花、黄芩,绿原酸含量,线性关系良好,回归方程Y=3258180.077X+5589.828,γ=0.9999,绿原酸的平均回收率为99.9%,RSD%为0.98%。结论:本方法简便,准确,重现性好,可作为本品质量控制。

Objective ： To establish the quality standard of Qifeizhike composition. Methods ： The TLC method was used to differentiate Flos lonicerace, Radix, Scuteuariae, etc; HPLC was used to determine chlorogenic acid. Result： Flos lonicerae , Radix Scuteuariae, the content of chlorogenic acid could be identified by TLC. Chlorogenic acid showed a good linear relationship. Y = 3258180.077X ＋ 5589. 828 ,γ = 0. 9999 The average recovery of chlorogenic acid .was 99.9%, RSD% was 0.98%. Conclusion： The method is simple, accurate with good reproducibility, can be used to control the quality of.Qifeizhike composition.
