[0002] Foliage leaf (FOLIUMISATIDIS) is the dried leaf of Isatis indigotica Fort., a cruciferous plant. It has the effects of clearing heat and detoxifying, cooling blood and eliminating spots. Jaundice, dysentery, mumps, sore throat, erysipelas, carbuncle [1] , Modern pharmacodynamic studies have shown that Folium Folium has pharmacological effects such as antibacterial, antiviral, anti-endotoxin, and immune enhancement. [2-6] , at present, the quality control method of Folium Folium is mainly based on the quantitative analysis of components such as indigo and indirubin [7，8] , not enough to control the quality of Folium Folium as a whole, as a commonly used clinical traditional Chinese medicine, its authenticity is affected by many factors such as its place of origin, harvest time, and drying conditions. Therefore, it is necessary to establish a scientific quality The detection method evaluates the quality of Folium Folium, (references: [1] Pharmacopoeia Committee of the People's Republic of China.
