Which makes them sound very much like two different compounds not that one contains the other http://www.answers.com/topic/poisonous-plant-botanyquote:Alkaloid-containing plantsAlkaloids, compounds containing a nitrogen atom, have specific pharmacological effects on both humans and animals. Found in many different plant families, they have been used in drug therapy since ancient times, but misuse of these plants can produce poisonings. The potato family (Solanaceae) has many species that contain a number of alkaloids. Hyoscyamine and atropine are the alkaloids occurring in belladonna or deadly nightshade (Atropa belladonna), black henbane (Hyoscyamus niger), thornapples and jimsonweed (Datura), and tree daturas or angel's-trumpets (Brugmansia). The black nightshades (Solanum) contain glycoalkaloids. Plants of tobacco, Nicotiana, contain numerous alkaloids, principally the very toxic nicotine or its isomer anabasine. Plants of poison hemlock (Conium macalatum) have several alkaloids similar to nicotine, which affect the central nervous system. Plants of rattlebox (Crotalaria), groundsel (Senecio), and fiddleneck (Amsinckia) have alkaloids of similar molecular structure. Anagyrine is a toxic alkaloid found in several species of lupine (Lupinus) in the western United States. Alkaloids present in species of monkshood (Aconitum) are extremely toxic. Larkspur plants (Delphinium) have similar toxic alkaloids affecting the central nervous system, causing excitability and muscular spasms. Plants of false hellebores (Veratrum) and death camas (Zigadenus) have complex alkaloids of similar structure and cause livestock deaths in the western United States. See also Alkaloid; Atropine.
