dc.description.abstract | [EN] Gentiana lutea L. subsp. aurantiaca M. Lainz is a plant endemic to the north-western
mountainous areas of the Iberian Peninsula. Its roots are widely used mainly because of the high
content of bitter compounds. The occurrence of these valuable bitter compounds in the roots is rather
inhomogeneous, resulting in fluctuating root quality. Methanolic extracts obtained from different
parts and tissues of wild and cultivated gentian, in and out of its natural environment, were analysed
using HPLC chromatography to investigate the variation in the concentration of amarogentin,
gentiopicroside, sweroside and swertiamarin. The distribution patterns of these compounds in the
different 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 analysed
compounds 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 more
biomass, while in those cultivated out of the natural environment, sweroside concentration was
higher. These results allow us to understand that, when cultivated, the variability in the concentration
of the different bitter compounds is linked with the edaphoclimatic conditions, but more importantly
that it is linked with the dominating kind of tissues and the root system structure, especially when
analysing the content of amarogentin and sweroside. The selection of plants with an optimal root system
structure for breeding may increase the yield in bitter compounds and contribute to developing
the commercial cultivation of this protected plant | es_ES |
