Comparison of Chemical Constituents in Pseudostellariae Radix with Different Dosage Forms Based on HPLC-Q-Exactive Orbitrap/MS Combined with Multivariate Statistical Analysis

<div>Hierarchical clustering analysis of PR decoction pieces and formula granules. Clear differentiation was observed in the heat map, colors varying from green to red graphically indicated that the relative contents of metabolites were from low to high. 98 and 52 differential chemical compositions were identified in the positive mode (a) and negative mode (b).</div>
