Objective To clarify the chemical components and quantify the main components, so as to provide the basis for the quality evaluation of Fanxieye (Sennae Folium). Methods UHPLC-Q-Exactive-Orbitrap-MS was employed to quickly identify the main chemical components of Sennae Folium in negative ion mode. Furthermore, the quantitative analysis of six main chemical components was accomplished by ultra performance liquid chromatography with photo-diode array (UPLC-PDA) detection in Sennae Folium. Results A total of 29 components were identified, including 12 anthraquinones, 11 flavonoids, two benzophenones and four naphthalenes. The content of six main components (vicenin 2, aloe emodin-8-O-glucoside, sennoside A, sennoside B, sennoside C, and tinnevellin glucoside) were determined in 20 batches Sennae Folium, which varied obviously in different batches. Conclusion The rapid identification of chemical components and the quantitative analysis of six components were successfully accomplished in Sennae Folium, which provided the basis for the quality evaluation of Sennae Folium.
