Study on quality control of Jinbei oral liquid based on fingerprint, chemical pattern recognition and multi-index content determination
To establish a quality control method for Jinbei oral liquid based on multi-wavelength switching high performance liquid chromatography (HPLC) fingerprint, chemical pattern recognition and multi-index content determination.
METHODS
2
A total of 15 batches of Jinbei oral liquid were used as test samples. The
Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine
(
Version 2012
) was adopted to establish multi-wavelength switching HPLC fingerprints, followed by chromatographic peak identification and similarity evaluation. Cluster analysis, principal component analysis and orthogonal partial least squares-discriminant analysis were applied to conduct chemical pattern recognition on the 15 batches of samples. The multi-wavelength switching HPLC method was used to simultaneously determine the contents of neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, forsythoside A, baicalin, salvianoli
c acid B and wogonoside in samples.
RESULTS
2
A total of 25 common peaks were calibrated in the fingerprints of 15 batches of Jinbei oral liquid, among which 7 common peaks were unambiguously identified. The similarity of all samples was higher than 0.960. Chemical pattern recognition results showed that samples S1-S8 were clustered into group 1, and samples S9-S15 were clustered into group 2. Baicalin, wogonoside, neochlorogenic acid, chlorogenic acid and salvianolic acid B were identified as the differential quality markers. The average contents of neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, forsythoside A, baicalin, salvianolic acid B and wogonoside in 15 batches of Jinbei oral liquid were 0.213 7, 0.085 3, 0.104 9, 0.287 3, 0.420 1, 0.062 1, 0.176 0 mg/mL, respectively.
CONCLUSIONS
2
The established quality control method for Jinbei oral liquid combining multi-wavelength switching HPLC fingerprint, chemical pattern recognition and multi-index content determination is stable and reliable, which can provide a reference for the formulation of quality standards of this preparation.
