**4.4 Final remarks**

PCA analyses based on atomic Cartesian coordinates of the properly oriented in the Cartesian system conformers of arbutin allowed the grouping of these conformers by structural analogies, which could be related with the conformationally relevant dihedral angles. Among them, the dihedrals interconnecting the glucopyranoside and phenol rings and those associated with the CH2OH fragment were found to be the most relevant ones.

In summary, this work represents a new simple approach for the structural analysis of complex molecules and its aim was also to show another application of PCA.
