what is the name of the poison isolated from Duscle garden nightshade?
Solanine Solanine is a glycoalkaloid poison found in species of the nightshade family within the genus "Solanum", such as the potato ("Solanum tuberosum"), the tomato ("Solanum lycopersicum"), and the eggplant ("Solanum melongena"). It can occur naturally in any part of the plant, including the leaves, fruit, and tubers. Solanine has pesticidal properties, and it is one of the plant's natural defenses. Solanine was first isolated in 1820 from the berries of the European black nightshade ("Solanum nigrum"), after which it was named.
Pyrethrin The pyrethrins are a class of organic compounds normally derived from "Chrysanthemum cinerariifolium" that have potent insecticidal activity by targeting the nervous systems of insects. Pyrethrin is synthetically made by industrial methods, but it also naturally occurs in chrysanthemum flowers, thus is often considered an organic insecticide, or at least when it is not combined with piperonyl butoxide or other synthetic adjuvants. Their insecticidal and insect-repellent properties have been known and used for thousands of years.
