This paper compares the differences in the content of chemical components of different varieties of lily and systematically organizes the pharmacological action mechanism of lily,in order to provide a reference for the in-depth study of the clinical use and phar-macological action mechanism of lily.Based on the keywords"lily""different varieties""chemical components""differences""pharma-cological effects",etc.,the relevant literature in recent years from databases such as Wanfang.com,Weipu.com,China National Knowl-edge Infrastructure,and Pubmed was collected,sorted,and summarized to draw conclusions:the content of chemical components of different varieties of lily is different,among which the content of most chemical components of Lilium lily is better than that of other varie-ties,and it can be used as the mainstream variety of medicinal lily;at present,there are relatively few studies comparing the differences in the pharmacological effects of different varieties of lily in terms of anti-tumor,improving immunity,anti-oxidation,sedation and hypno-sis,and lowering blood sugar,which can be further studied.
