RESUMEN
Sedum emarginatum Migo (Aoyejingtian) is a perennial succulent herb of the sedum genus in the family Crassulaceae, which has the fountion of treating furuncle, swelling and haematemesis, hematochezia, menorrhagia and hepatitis. Preliminary studies of our research group had showed that the ethyl acetate extract of Sedum emarginatum Migo could inhibit the proliferation of liver cancer HepG2 cells. The establishment of a reasonable and feasible quality evaluation method for the effective parts of Sedum emarginatum Migo can provide a scientific basis for the further development and utilization of Sedum emarginatum Migo. In this study, a multi-wavelength conversion method was used to establish high-performance liquid chromatography (HPLC) fingerprints of the ethyl acetate extract of Sedum emarginatum Migo, and the method was also used to simultaneously determine the gallic acid, protocatechuic acid, caffeic acid, and ferulic acid, isoquercitrin and luteolin in the ethyl acetate extract of Sedum emarginatum Migo. The similarity of the fingerprints of the ethyl acetate extract of Sedum emarginatum Migo from different origins and the content of 6 components were compared. The established method was simple, accurate, table and reliable, which could provide a fast, accurate and reliable method for comprehensive evaluation of the quality of Sedum emarginatum Migo.
