ABSTRACT

Objective:

To establish a UPLC fingerprint method of Paeoniae Alba Radix, and provide comprehensive evaluation of their quality in different regions.

Methods:

The UPLC chromatographic column was Acquity UPLC® HSS T3 (100 mm × 2.1 mm, 1.8 μm). The mobile phase was acetonitrile-0.05% phosphoric acid water with gradient elution. The detection wavelength was 230 nm and column temperature was 30 ℃ with the flow rate of 0.4 mL/min. Similarity analysis, hierarchical clustering analysis, and principal component analysis were undertaken to study 23 sets of UPLC fingerprints of Paeoniae Alba Radix.

Results:

A specific UPLC fingerprint of Paeoniae Alba Radix was established and eight common peaks were designated. The results showed that the qualities of the 23 sets of Paeoniae Alba Radix were not stable and the samples collected from same region and different regions both had certain differences.

Conclusion:

UPLC fingerprint is an available and convenient method which can be used to access the quality of Paeoniae Alba Radix rapidly.
