成分。结果 所建UPLC方法精密度、重复性、稳定性的RSD均不大于4.4%。在13批精天颗粒指纹图谱中共标定出25个共有峰;
通过与对照指纹图谱比对,指认了其中10个共有峰,分别为3号峰(5-羟甲基糠醛)、5号峰(红景天苷)、8号峰(绿原酸)、15号峰

13批样品指纹图谱的相似度为0.955~0.996。HCA结果显示,13批样品可聚为3类,其中S1、S5、S7、S11~S13为一类,S4、S6为
一类,S2、S3、S8~S10为一类。PCA结果显示,主成分1~7的累计方差贡献率为92.666%。OPLS-DA进一步确定了13个差异性

ABSTRACT OBJECTIVE To establish the ultra-high performance liquid chromatography (UPLC) fingerprint of Jingtian
granule, and to evaluate its quality by chemical pattern recognition. METHODS Luna Omega Polar C18 column (150 mm×2.1
®
mm, 1.6 μm) was used as the chromatographic column, and acetonitrile-0.2% phosphoric acid solution was used as the mobile
phase for gradient elution. The flow rate was 0.2 mL/min, the column temperature was 30 ℃, and the detection wavelength was
265 nm. With peak 16 as the reference peak, the UPLC fingerprint of Jingtian granule was established by the Similarity Evaluation
System of Chromatographic Fingerprint of Traditional Chinese Medicine (2012 edition). The common peaks were identified, the
similarity evaluation was carried out, and the ownership of each common peak was confirmed. Hierarchical cluster analysis (HCA)
and principal component analysis (PCA) in chemical pattern recognition methods were used to classify 13 batches of samples (S1-
S13), and orthogonal partial least squares-discriminant analysis (OPLS-DA) was used to identify the key components of the
differences between different batches of samples. RESULTS RSDs of precision, repeatability and stability of the UPLC method
were not more than 4.4%. A total of 25 common peaks were identified in the fingerprints of 13 batches of Jingtian granules. By
comparing with the reference substance fingerprint, 10
