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

Figure 6

Comparative analysis of contents of differential chemical compositions in PR decoction pieces and formula granules. (a) The relative contents of differential chemical compositions in PR decoction pieces > PR formula granules in the positive mode. (b) The relative contents of differential chemical compositions in PR decoction pieces < PR formula granules in the positive mode. (c) The relative contents of differential chemical compositions in PR decoction pieces > PR formula granules in the negative mode. (d) The relative contents of differential chemical compositions in PR decoction pieces < PR formula granules in the negative mode.
