Abstract: OBJECTIVE: To evaluate the medicinal reasonableness and resource utilization of Dida from different species.METHOD: With common characteristic absorption peaks of HPLC fingerprints and SPSS cluster, the composition similarity of Dida from different species was evaluated. RESULT: The composition similarity of HPLC fingerprints of 33 Dida samples from 15 species and 1 variety originated from Swertia, Halenia, Gentianopsis, Lomatogonium was difference. The original species can be clustered into four groups by the relative area of 10 common characteristic peaks of HPLC fingerprints. The compositions of four different genera are quite different. CONCLUSION: Because of containing iridoids, xanthones, and triterpenes which have liver protection and cholagogue functions, all of species from Swertia, Halenia, Gentianopsis and Lomatogonium in Gentianaceae are classified as Dida in Tibetan medicine. According to the composition difference among different species, the HPLC fingerprints established for Dida from different source are an effective means to identify nd control the quality of Dida.
