If a potato has sprouted, all the sprouts should be removed before the potato is cooked. Green patches in potatoes represent areas where chlorophyll has been produced.Foods from the Nightshadefamily of plants (Solanaceae) all contain the chemical solanine, which is a naturally-occurring toxin found in a number of different plants. For example, Tomatoes contain tomatine; eggplants contain alpha-solanine; capsicums and chillies contain solanadine and potatoes (not sweet potatoes) possess solanine.Tomatine is a poisonous compound found in all parts of the tomato plant but is largely concentrated in the leaves and stems.
