Alkaloids found in Solanaceae

450px|thumb|right|Chemical structure of α-solanine distinguishing the sugar (solatriose moiety) and the alkaloid ([[solanidine moiety) portions]] Glycoalkaloids are a family of chemical compounds derived from alkaloids to which sugar groups are appended. Most have a bitter taste and confer some protection against plant pathogens and herbivores. Several are potentially toxic to humans, most notably the poisons commonly found in the plant species Solanum dulcamara (bittersweet nightshade) and other plants in the genus Solanum, including potato. Some are antinutritional factors. They are an examp

Cuscohygrine is a bis N-methyl pyrrolidine alkaloid found in coca plants. It can also be extracted from plants of the family Solanaceae, including Atropa belladonna (deadly nightshade) and various Datura species. Cuscohygrine usually occurs along with other, more potent alkaloids such as atropine or cocaine.

Anatabine (uh-nat-uh-been,-bin) is one of the minor alkaloids found in plants in the family Solanaceae, which includes the tobacco plant and tomato. Commercial tobacco plants typically produce alkaloids at levels between 2% and 4% of total dry weight, with nicotine accounting for about 90% of the total alkaloid content, and the related compounds anatabine, nornicotine, and anabasine making up nearly all the rest. These compounds are thought to be biologically active, and part of plants' natural defense system against insects.
