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).
Principle glycoalkaloids present in potato are a-chaconine and a- solanine (Freidman and McDonald 1997).
