DETERMINATION OF THE GLYCOALKALOIDS CONTENT FROM POTATO TUBERCULES (SOLANUM TUBEROSUM)

Abstract

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.
