Zusammenfassung

In der Heilpflanze Thymus capitatus Hoffm. und Link wurden mit Hilfe der Neutronenaktivie-rungsanalyse die Spurenelemente Sb, Cl, Cr, Cs, Co, Eu, Fe, Mn, K, Rb, Sc, Na und Zn sowie durch Wasserdampfdestillation und Gas-Chromatographie die ätherischen Öle und Phenol bestimmt. Zwischen Pflanzen aus zwei verschiedenen Regionen ergaben sich für die aktiven Bestandteile sowie für die Spurenelemente Cr, Fe, Eu und Mn statistisch signifikante Unterschiede. Diese Elemente werden daher als entscheidende Faktoren für die erhöhte Konzentration an aktiven Bestandteilen (bis zu 25%) angesehen.

Summary

In the medicinal plant Thymus capitatus Hoffm. and Link the trace elements Sb, Cl, Cr, Cs, Co, Eu, Fe, Mn, K, Rb, Sc, Na and Zn were determined by neutron activation analysis and the essential oils and phenol by steam distillation and gas chromatography. Statistically significant differences were found between plants from different regions for the active constituents and for the elements Cr, Fe, Eu and Mn. These latter elements are therefore regarded as decisive factors for the increase of the active constituents (by up to 25%).
