Solanine is a bitter-tasting steroidal alkaloid saponin that has been isolated from all nightshades, including tomatoes, capsicum, tobacco, and eggplant. However, the most widely ingested solanine is from the consumption of potatoes. Potato leaves, stems, and shoots are naturally high in this saponin.
Is solanine a chemical reaction?
Tubers damaged in harvesting and/or transport also produce increased levels of glycoalkaloids; this is believed to be a natural reaction of the plant in response to disease and damage. Also, the tuber glycoalkaloids (such as solanine) can be affected by some chemical fertilization.
Are green potatoes a chemical contamination?
While chlorophyll is a harmless chemical, its presence in potatoes indicates that the tubers have also increased their production of a glycoalkaloid known as solanine. Solanine protects potatoes and other plants in the family Solanaceae from herbivory and serves to preserve the sprouting spud from hungry animal mouths.
What is solanine?
Most solanine occurs in the skin or just under the skin of potatoes. Peeled potatoes have been found to contain 30-80% less solanine than unpeeled potatoes, and green potatoes should always be peeled if they are to be used at all. Solanine and chaconine are also present in potato shoots.
Is solanine a drug?
Solanine A is a novel steroidal alkaloid isolated from Solanum nigrum Linn., a medicinal and edible plant which is widely used for treating various inflammatory diseases.
