Daqingye(Isatidis Folium)is the dried leaves of Songlan(Isatis indigotica Fort). Its chemical composition mainly includes alkaloids,organic acids,flavonoids,lignans,etc.,with antiviral,anti-endotoxin,anti-inflammatory,antibacterial,antioxidant,anti-tumor,immune regulation and other effects. Based on the research progress of chemical components and pharmacological effects of Daqingye(Isatidis Folium),the quality markers of Daqingye(Isatidis Folium)were predicted and analyzed from the aspects of transmission and traceability,plant genetics,chemical component specificity,effectiveness and measurability. It is predicted that indirubin,indigo,tryptanthrin,4(3H)- quinazolinone,1,2,2'-tri-O-E-sinapoyl-β-gentiobiose,1,2,6'-tri-O-E-sinapoylgentiobiose,isovitexin,isoscoparin and lariciresinol can be used as the candidate compounds of the quality markers of Daqingye(Isatidis Folium),which can provided a reference for improving the quality evaluation system of Daqingye(Isatidis Folium).
