[Research progress on saponins, biological activities of saponins, and quality control of Panax quinquefolium].

Panax quinquefolium, as a common precious medicinal plant, has complex chemical components and unique pharmacological activities, which can play a healthcare role in the human body. With the deepening of research, the application of P. quinquefolium has become increasingly extensive. This paper summarized the research progress of the saponins isolated and identified from diffe-rent parts of P. quinquefolium, the structural classification and pharmacological activities of the saponins, and the quality control of Panacis Quinquefolii Radix. Further, this paper put forward the urgent problems to be solved in the development of P. quinquefolium. It is hoped to lay a foundation for the further study and provide reference for the research direction of P. quinquefolium.
