摘要
目的:建立消脂护肝片中总黄酮的含量测定方法。方法:采用分光光度法,以芦丁为对照品,对其进行络合显色,在510nm波长处测定吸光度,从而测定消脂护肝片中总黄酮的含量。结果:线性范围在0.008～0.08mg.mL-1(r=0.9997),平均回收率为97.0%,RSD=1.84%(n=6)。结论:该法简便易行、重现性好、结果可靠,可用于该制剂的质量控制。
Objective： To establish ultraviolet sepctrophotometry for the determination of total flavones in Xiaozhihugan tablets. Methods： Quercetin was selected as reference material,and the samples were determined at 510 nm. Results： The linear range for quercetin was 0. 008 - 0. 08 mg· mL^-1 （ r = 0. 999 7 ）. The recovery rate was 97.0 %, RSD = 1.84 % （n = 6） . Conclusion： This method is easy to handle with good accuracy and reproducibility, and is suitable for the quality control of Xiaozhihugan tablets.
