Tubers may contain toxic alkaloids as solanine and chaconine
However, the cultivated potato contains low glycoalkaloid levels, typically only solanine and chaconine
, suggesting these bitter compounds were selected against during domestication (Johns & Alonso, 1990).

and solanine, glycoalkaloids normally present in potatoes, also were detected.
The nutritional value of potato protein depends on the level of glycoalkaloids such as solanine and chaconine
and their secondary metabolites (Friedman, 1996).
TAKE CARE: Potatoes which have gone green contain SOLANINE and CHACONINE
which are poisonous and can cause migraine and drowsiness.
