Objective: To establish the analytical method for the fingerprint of Salviae Miltiorrhizae Radix et Rhizoma by HPCE-DAD and estimate its quality.
Methods: Salviae Miltiorrhizae Radix et Rhizoma were analyzed and the chromatographic fingerprint were determined by HPCE-DAD. The data were analysed by fuzzy cluster and fingerprint similarity evaluation software was used to compare the similarity of samples.
Results: HPCE-DAD fingerprint of 10 main common peaks was established preliminarily. It was discovered that a small number of samples were different from the others.
Conclusion: The method is reliable, accurate and can be used for the quality control of Salviae Miltiorrhizae Radix et Rhizoma
