ABSTRACT
Objective:
To established fingerprint of Acanthopanacix Cortex by UPLC method, in order to provide reference for quality control and evaluation.Method:
UPLC method was performed on Waters BEH C18 (2.1 mm×100 mm, 1.7 μm), with acetonitrile-0.1% glacial acetic acid as the mobile phase for gradient elution.The detection wavelength was 282 nm, the flow rate was 0.3 mL·min-1, the column temperature was 25 ℃, and the injection volume was 2 μL.With syringin as reference substance, the fingerprint of 20 batches Acanthopanacix Cortex were analyzed under the same chromatographic conditions.The Similarity Evaluation System for Chromatographic Fingerprint of Chinese Materia Media (version 2012) was used to analyze the similarity of 20 batches of Acanthopanacix Cortex, and the SPSS 21.0 was applied for cluster analysis.Result:
The UPLC fingerprint of the Acanthopanacix Cortex was established.The similarity results showed that the 7 batches of the 20 batches of Acanthopanacix Cortex was less than 0.800, and the remaining medicinal materials were similar within the range from 0.800 to 0.924.Besides, 12 common fingerprint peaks were calibrated and 4 components were identified, namely protocatechuic acid (peak 1), chlorogenic acid (peak 3), syringin (peak 4), and 4-methoxysalicylaldehyde (peak 12). The clustering results showed that the 20 batches of Acanthopanacix Cortex were divided into four groups.Among these batches, S1, S3, S9, S13 and S20 were clustered into one category, S11 was a category, S14 was a category, and the remaining samples belonged to a category.Conclusion:
With a good precision, repeatability and stability, short analysis time as well as superior specificity, the method will provide a scientific basis to evaluate and control the quality of Acanthopanacix Cortex.
