Non-averaged unsupervised hierarchical clustering of the phenolic profiles of Lupinus albus, luteus and cossentinii (similarity: Euclidean; linkage rule: Ward). The compounds’ intensity was used to build up a heat map, on the basis of which the clusters were generated. LA: L. albus; LL: L. luteus; LC: L. cossentinii.
