Objective; To establish the chromatographic fingerprints for the anti-tumor flavonoids of Caulis spatholobi (SSCE). It could used to reflect the chemical information in this part comprehensively, and identify the chemical constituents preliminarily. Method: The HPLC-DAD analysis method was performed on the column Kromasil 100-5PHENYL (4. 6 mm×250 mm, 5uμm). The mobile phase was water(0. 5% acetic acid)- methanol in gradient elution and the detection wavelength was 254 run. Result; The chromatographic fingerprint of SSCE was established, which showed 16 characteristic peaks from 10 batches of medicinal materials. Among them, the peaks 1,3,4,5,8,9, 10, 12, 13, and 16 were identified 3,4-dihodroxybenzoic acid, 4-Hydroxybenzoic Acid, epicate-chin, puerarin, daidzein, liquiritigenin, calycosin, genistein, formononetin, and prunetin, respectively. Conclusion; The method is convenient, reproducibility and stability. It can used for quality control of the anti-tumor flavonoids of C. Spatholobi (SSCE).
