Figure 4. 

Cluster diagram of differential metabolites present in three types of Pulsatilla medicinal materials. (a) Total differential metabolites; (b) differential metabolites of triterpenoid saponin components; (c) differential metabolites of nontriterpenoid saponin components.

Figure 5. 

(a) Volcano plot of differential metabolites between P. chinensis var. kissii and P. chinensis; red and green colors represent the numbers of metabolites with significant differences among the metabolites. Upregulated metabolites are depicted in red, whereas downregulated metabolites are shown in green. (b) Cluster heatmap of differential metabolites between P. chinensis var. kissii and P. chinensis.
