When the potato greens, solanine increases to potentially dangerous levels. Hence it is advised not to eat the green parts of the potato. Commercial varieties of potatoes are screened for solanine levels, and most have a solanine content of less than 0.2mg/g. However potatoes that have been exposed to light and started to green can show concentrations of 1mg/g or more.
