[HPLC Characteristic Fingerprint of "Boju" Chrysanthemum morifolium]
Objective:
To provide a scientific basis for quality control of "Boju" Chrysanthemum morifolium by establishing a HPLC characteristic fingerprint.
Methods:
The HPLC analysis was performed on a Spursil C18 chromatographic column (250 mm x 4. 6 mm, 5 µm), and the mobile phase was acetonitrile-0. 1% phosphoric acid in a gradient mode with the flow rate of 1. 0 mL/min. The detection wavelength was 325 nm and the temperature of column was 30 °C.
Results:
The common pattern of HPLC characteristic chromatographic profile was established. There were 16 common peaks, five of which were identified in the pattern. The similarities of 10 batches of "Boju" Chrysanthemum monrfolium were evaluated, and all of them were greater than 0. 900.
Conclusion:
This analysis method of HPLC characteristic chromatographic fingerprint is simple and reproducible, and it can provide a scientific basis for identification and quality evaluation of "Boju" Chrysanthemum monfolium.
