ABSTRACT

Objective:

To establish the HPLC fingerprint and multicomponents determination of Potentillae Chinensis Herba, and provide a scientific basis for the improvement of its quality standards.

Methods:

The separation was performed on a chromatographic Diamonsil C18 column (250 mm × 4.6 mm, 5 μm), with acetonitrile-0.1% phosphoric acid as the mobile phase for gradient elution. Volume flow rate was 1.0 mL/min. Column temperature was 25 ℃. Injection was 10 μL and the detection wavelength was 260 nm. The fingerprints of 10 batches of Potentillae Chinensis Herba were established and evaluated by the similarity evaluation system of TCM (version 2004A), which were divided into two categories by clustering analysis. Meanwhile, the content of galic acid, quercetin, and kaempferol was determined.

Results:

The fingerprint of Potentillae Chinensis Herba was established. There were 12 common peaks in the fingerprint. Galic acid, quercetin, and kaempferol were separated with good linearity relationships (r > 0.999). The average recovery rates of the investigated compounds were 97.44%, 97.64%, and 99.19%, respectively.

Conclusion:

The established fingerprint and multicomponents determination method of Potentillae Chinensis Herba have strong specificity and good repeatability, which can effectively control the internal quality of Potentillae Chinensis Herba and provide reference for improving the quality evaluation method of Potentillae Chinensis Herba.
