Abrin and ricin are natural protein toxins isolated from plant seeds i.e., they are phytotoxins. Concanavalin A is a lectin (carbohydrate -binding protein) originally extracted from the jack-bean, Canavalia ensiformis. Morphine and codeine are alkaloids derived from opium, and are called opioid narcotics.
