Alkaloid from Atropa, Datura, Duboisia, Hyoscyamus and Scopolia spp. and several other genera in the Solanaceae, esp. some strains of Duboisia myoporoides. Used in medicine as a mydriatic. Mp 108-111°. [a][f — 22° (50% EtOH aq.). Racemises slowly in EtOH to Atropine, more rapidly in alkali or on melting sometimes occurs naturally as partial racemate. 

The family Solanaceae is one of the important and interesting plant families. It may be classified into four groups based on their usefulness and chemical composition of alkaloids contained (1) Nicotiana spp. such as N. tabacum and N. rustica, which provide tobacco and contain nicotiana alkaloids such as nicotine and nomicotine (2) Hyoscyamus, Scopolia, Atropa, and Datura species, which are pharmacologically important and contain tropane alkaloids such as hyocyamine, scopolamine, and tropine (3) Solanum spp., which are sometimes the starting material for production of synthetic steroids for medical uses and which contain solanum alkaloids and (4) Capsicum, Solanum, and Lycoper-sicum species, which serve as foods and are alkaloid-free.
