Chaconine

α-Chaconine is a steroidal glycoalkaloid that occurs in plants of the family Solanaceae. It is a natural toxicant produced in green potatoes and gives the potato a bitter taste. Tubers produce this glycoalkaloid in response to stress, providing the plant with insecticidal and fungicidal properties. It belongs to the chemical family of saponins. Since it causes physiological effects on individual organism, chaconine is considered to be defensive allelochemical. Solanine is a related substance that has similar properties.
