DELGADO, Wilman A  and  CUCA S, Luis E. Classification of ethanolic extracts from Lauraceae species by two-dimensional thin layer chromatography and multivariate statistical analyses 2D-TLC/PCA-cluster. Rev.Colomb.Quim. [online]. 2016, vol.45, n.1, pp.10-14. ISSN 0120-2804.  https://doi.org/10.15446/rev.colomb.quim.v45n1.58608.

Leaves and barks ethanolic extracts from 13 Lauraceae species were characterized through two-dimensional thin layer chromatography (2D-TLC). The subsequent data was analized through multivariate statistical analysis techniques (cluster analysis and principal components analysis (PCA)). This allowed to do a distinction between extracts obtained from different parts of the plant (leaves and bark). In addition, it was observed that the implemented methodology is able to differentiate between extracts obtained from Lauraceae species and some obtained from other plant families.

Keywords : Two-dimensional thin layer chromatography (TLC-2D); principal components analysis (PCA); Lauraceae; metabolic profile; chemical diversity.
