Nitraria tangutorum Bobr. is a kind of desert plant with medicinal,edible,and feeding values,widespread in arid and semi-arid areas in northwest China.Known as desert cherry,N. tangutorum contains a variety of nutrients,and is also rich in flavonoids,alkaloids,and other medicinal ingredients,therefore,medicinal composition,content,efficacy,and pharmacology of N. tangutorum have been studied.In this paper,the existing studies on flavonoids of N. tangutorum were investigated.Firstly,the flavonoids isolated from N. tangutorum were classified;secondly,the content of total flavonoids in main tissues of N. tangutorum were sorted and analyzed;in addition,the content of various flavonoid compounds in N. tangutorum were analyzed;finally,the pharmacodynamics and pharmacology of flavonoids,various flavonoids and flavonoid monomer compounds in N. tangutorum were reviewed.Through the sorting and analysis of the above contents,a series of problems in the medicinal research of flavones in N. tangutorum were summarized,and based on these problems,the ideas to solve the existing problems were proposed,and the suggestions for future research on the medicinal use of flavone in N. tangutorum were also proposed.This work would provide theoretical reference for the medicinal research and development of plant flavonoids of N. tangutorum and promote the development of traditional Chinese medicine industry.
