DATA TO THE CHEMICAL VARIABILITY OF CONVALLARIA MAJALIS L. |
| Authors: | A. Máthé, W. Kubelka |
| Abstract:
Hungarian native populations of the species consist of different proportions of botanical forms (f.monophylla, f.majalis and f.trifolia). The formation of these forms is in connection with the polycormone character of the species, and to some extent is the manifestation of plant age. A coherent polycormone can bear above-ground shoots of different botanical forms. The morphological variability is also manifested in the active principles. Total cardenolide content and production of shoots growing from ontogenetically older rhizome parts are significantly higher than those of younger ones. Hungarian native populations sampled by the large two-leaved above-ground shoots are homogenous in their glycoside spectra. The main components are convalloside and convallatoxol. Within one population plant individuals (coherent polycormones) manifest a variability in their glycoside spectra, similar to that experienced by plant samples of different geographic origin. | |
