摘要
目的:建立桑姜感冒胶囊中总黄酮含量的测定方法。方法:采用紫外-可见分光光度法,以芦丁为对照品,以506 nm作为测量波长进行测定。结果:芦丁在0.5~3.0 mg范围内与吸光度呈良好的线性关系(r=0.999 7),平均回收率为96.63%,RSD为1.91%。结论:该方法操作简便、准确、重现性好,可用于测定桑姜感冒胶囊中总黄酮的含量。
Objective: To establish UV spectrophotometry method for the determination total flavonoids in compounds of Sangjiang Ganmao capsule. Methods: The contents of the total flavonoids were determined at 506 nm with rutin as the standard substance by ultraviolet UV-visible method. Results: The calibration curve was linear in the range of 0.5-3.0 mg for rutin, r=0.999 7; the average recovery was 96.63%, RSD= 1.91% (n=6). Conclusion: This method is simple, fast and accurate, and can be used as the determination of the total flavonoids in compound Sangjiang Ganmao capsule.
