摘要

[Objectives] This study was conducted to understand Radix Rehmannia quality and provide reference for selection in application. [Methods] The contents of flavonoids in five batches of commercially available samples were determined by ultraviolet spectrophotometry, and the precision and reproducibility of the determination method were analyzed. [Results] The contents of flavonoids in different batches of Radix Rehmannia samples were not completely the same, but the differences were not large overall. The experiment results have good reliability. As a medicinal plant, the climate and soil conditions of the producing areas would have an impact on the quality of Radix Rehmannia. [Conclusions] The contents of flavonoids determined in Radix Rehmannia were relatively stable, the quality was basically the same, and the overall quality was good.
