ZHOU Huiying,WANG Yuan,WANG Yani,et al.Quality evaluation of Qingwen hufei granules based on fingerprints combined with multi-component content determination[J].ZHONGGUO YAOFANG,2026,37(03):338-343.
To provide a scientific basis for the quality evaluation and clinical application of Qingwen hufei granules.
METHODS
2
Fourteen batches of Qingwen hufei granules were used as samples to establish high-performance liquid chromatography (HPLC) fingerprints using the
Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine
(
2012 Edition
). The chromatographic peaks were identified and the similarity was evaluated. Cluster analysis (CA), principal component analysis (PCA), and orthogonal partial least squares-discriminant analysis (OPLS-DA) were used to conduct chemical pattern recognition analysis on the 14 batches of samples. Meanwhile, the contents of neochlorogenic acid (NGA), chlorogenic acid (CHA), cryptochlorogenic acid (CGA), forsythoside A (FTA), 3,5-
O
-dicaffeoylquinic acid (3,5-O-DA), 4,5-
O
-dicaffeoylquinic acid (4,5-O-DA), and angoroside C (AGC) in the samples were determined by HPLC.
RESULTS
2
The methodological investigation results of both the fingerprint and the content determination complied with the relevant requirements. Fourteen common peaks were indicated in the HPLC fingerprints of the 14 batches of samples, and 7 of them were identified [NGA (peak 2), CHA (peak 3), CGA (peak 5), FTA (peak 11), 3,5-O-DA (peak 12), 4,5-O-DA (peak 13), and AGC (peak 14)]; the similarity of each sample was greater than 0.94. The results of CA and PCA showed that the samples could be classified into 3 categories; the results of OPLS-DA indicated that peak 4 (unknown), peak 11 (FTA), peak 8 (unknown), peak 9 (unknown), and peak 1 (unknown) were the differential components. The content ranges of NGA, CHA, CGA, 3,5-O-DA, FTA, 4,5-O-DA and AGC in the 14 batches of samples were 0.210 4-0.458 7, 0.269 1-0.506 3, 0.228 1-0.461 1, 0.443 9-1.044 6, 0.066 7-0.155 7, 0.062 8-0.143 8, and 0.057 4-0.105 7 mg/g, respectively.
CONCLUSIONS
2
The HPLC fingerprint and multi-component content determination methods established in this study are efficient and reliable, and can be used for the quality evaluation of Qingwen hufei granules.
