From: Exploring novel secondary metabolites from natural products using pre-processed mass spectral data
The heatmap of all 236 RMSs from A. pilosa (117 for roots and 119 for aerial parts), which each consist of more than four raw spectra (a). The HCA was performed with Pearson correlation method as the distance measure and ward.D linkage as the clustering method. The dendrograms for the regions encompassed by the dashed boxes (b–f) in the heatmap display the leaves for compounds 1–43, which are shown in violet for pilosanidins (1–5) and pilosanols (6–15), blue for agrimolides (16–22), dark red for chromones (22–26), yellow for triterpenes (23–35) and sky blue for flavonoids (36–43).
