摘　　要：蒽醌类化合物具有泻下利尿等生物活性,是大黄的主要有效成分,因此蒽醌类成分的含量高低在很大程度上决定了大黄的品质,测定蒽醌类成分的含量可以更好的了解和使用大黄。本文采用723PC可见分光光度计,测定了大黄酸、大黄素和芦荟大黄素三种蒽醌化合物,设备简单,操作方便快速,且准确性能达到实验要求,值得蒽醌化合物含量测定的推广应用。The anthraquinone compounds are the main effective components of rhubarb, so the content ofanthraquinones determines the quality of rhubarb, and the be better understood and used. In this paper, the 723 PC visible spectrophotometer was used to determine the three anthraquinone compounds of rhein, emodin and aloe-emodin, the equipment is simple, the operation is convenient and fast, and the accurate performance meets the experimental requirements, which is worthy of the popularization and application of the determination of anthraquinone compounds.
