DETERMINATION OF THE GLYCOALKALOIDS CONTENT FROM POTATO TUBERCULES (SOLANUM TUBEROSUM)
Keywords:
potato, glycoalkaloids, solanine, chaconine, solanidine, lyophilisationAbstract
Determinations concerning the glycoalkaloids content were made over four potato
varieties (Hansa, Sieglinde, Nicola and Linda) obtained from a private German
source, country in which potatoes are cultivated and consumed frequently. Potatoes
have been cultivated in classic conditions, as well as in biodynamic conditions.The
glycoalkaloids complex and their aglycones had been obtained through a sequence
of operations, like extractions with several specific solvents at reflux and in
backward flow, hydrolysis, lyophilisation etc.The determinations concerning the
glycoalcaloids content of the four studied potato varieties were accomplished
comparatively for both culture modes, in classic and biodynamic conditions.
