ABSTRACT
There are 16 species and 7 varieties of medicinal plants of Trollius in China, with effects in clearing heat, detoxification and swelling, they are used for the treatment of acute and chronic tonsillitis, acute otitis media, chronic bronchitis and urinary tract infections. Through retrieval of literatures on nasturtium from 1972 to 2019 in a number of databases, such as CNKI, Wanfang Database, Baidu Academic and PubMed, the cultivation and quality control methods, extraction and purification processes, chemical composition, pharmacological effects, pharmacokinetics and metabolism of medicinal plants of the genus nasturtium were summarized. The researches of cultivation mainly focus on the establishment of seed treatment and tissue culture system. Quality control is mainly based on orientin and flavonoids. Research on extraction and purification technology mainly focused on the extraction and purification of total flavonoids. In terms of chemical composition, there are currently more than 100 major compounds isolated from this genus, including flavonoids, organic acids, alkaloids, coumarins and styrenes. Among them, there are 80 flavonoids, 12 organic acid monomers, 3 alkaloid monomers, 4 coumarin monomers and 14 styrene monomers. In terms of pharmacological action, there are mainly in vitro experiments of crude extracts of medicinal materials. The data of pharmacokinetics and metabolism mainly focus on the study of flavone monomers.
