Abstract:
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.
Key words: Sangjiang Ganmao capsule, total flavonoids, UV-visible method
