AB [EN] Gentiana lutea L. subsp. aurantiaca M. Lainz is a plant endemic to the north-westernmountainous areas of the Iberian Peninsula. Its roots are widely used mainly because of the highcontent of bitter compounds. The occurrence of these valuable bitter compounds in the roots is ratherinhomogeneous, resulting in fluctuating root quality. Methanolic extracts obtained from differentparts and tissues of wild and cultivated gentian, in and out of its natural environment, were analysedusing HPLC chromatography to investigate the variation in the concentration of amarogentin,gentiopicroside, sweroside and swertiamarin. The distribution patterns of these compounds in thedifferent analysed fractions showed that the concentration of bitter compounds varies significantly.Amarogentin is much more highly concentrated in the secondary roots, and all of the analysedcompounds were found in a significantly higher content in the root cortex than in the vascular tissues.Roots cultivated in the natural habitat showed much higher concentrations in amarogentin and morebiomass, while in those cultivated out of the natural environment, sweroside concentration washigher. These results allow us to understand that, when cultivated, the variability in the concentrationof the different bitter compounds is linked with the edaphoclimatic conditions, but more importantlythat it is linked with the dominating kind of tissues and the root system structure, especially whenanalysing the content of amarogentin and sweroside. The selection of plants with an optimal root systemstructure for breeding may increase the yield in bitter compounds and contribute to developingthe commercial cultivation of this protected plant
