Abstract:
Objective: In order to provide a scientific basis for the quality control of Kunxian Capsules (KC), HPLC characteristics chromatogram combined with multi-components determination was established. Methods: The analysis was performed on Agilent Zorbax SB-C18 column (250 mm × 4.6 mm, 5 μm), using acetonitrile and 0.1% phosphoric acid solution as the mobile phase at a flow rate of 0.8 mL/min for gradient elution, the column temperature was 33 ℃, and the detection wavelength was 270 nm. The fingerprints of 15 batches of KC were established and evaluated by the similarity evaluation system of TCM (2012A version), hierarchical cluster analysis and discriminant analysis of partial least squares. Furthermore, the content of hyperoside, epimedin A, epimedin B, epimedin C, icariin and baohuoside Ⅰ were determined. Results: The HPLC fingerprint with 21 common peaks of KC was established, and the similarities of samples were over 0.9. The linearity relationships separated with hyperoside, epimedin A, epimedin B, epimedin C, icariin and baohuoside Ⅰ were good, and the contents of the above-mentioned components in 15 batches of preparations were 2.817-7.527, 7.287-9.103, 8.730-18.675, 33.377-70.371, 35.297-50.291 and 4.059-9.079 mg/g, respectively. Conclusion: The combination methods of HPLC characteristic chromatograms and simultaneous determinations of multiple components are rapid, simple and reproducible, which can provide methodological reference for the quality control of KC.
