Datura genus

The subsequent detailed analysis of the alkaloid profiles of diploid- and tetraploid- transformed root cultures of D. stramonium L., cultivated in liquid medium, revealed that the studied cultures biosynthesized alkaloids that are untypical of intact plants 3-tropoyloxy-6-acetoxytropane 33 (new for Datura genus), methylecgonine 34 (new for the Solanaceae family), and 3-tigloyloxy-6-propionyloxy-7-xydroxytropane 35 (a new tropane ester) [24]. 

Atropine and scopolamine are alkaloids produced by members of the plant family Solanaceae which includes belladonna Atropa belladonna -source of atropine), henbane Hyoscyamius niger- the source of scopolamine), tomatoes, potatoes, green peppers, eggplant, and members of the Datura subfamily or genus, thornapple, Jimson or Jamestown weed, angel s trumpet, stinkweed, mandrake, and devil s apple. In the eatable plants it is the green portions which are poisonous vines, leaves, and sprouts. 

Scopolamin may be isolated from seeds of Datura innoxia genus Solanaceae.

A few new alkaloids have been isolated during investigations on Australasian plants. The major alkaloid of two Australian shrubs, Anthocercis viscosa R. Br. and A. fasciculata F. Muell. (fam. Solanaceae), has been identified as (—)-hyo-scyamine. The same base (partly racemic) is one of the seven alkaloidal constituents of A. littorea Labill. another is meteloidine. The major alkaloid, however, is littorine, which has been identified as R-(—)-3a-(2-hydroxy-3-phenylpro-pionyloxy)tropane (1). The isolation of tropane alkaloids from the Anthocercis species justifies the inclusion of this genus in the Solanaceae previously it had been included in the Scrophulariaceae but had recently been transferred to the Solanaceae on botanical grounds. Recently, littorine has also been isolated from Datura sanguinea R. and P. ... 

Pigs can tolerate small daily doses of datura seeds for long periods (92), while poultry have a very high resistance to it and can tolerate up to 15 gm per day (93). Members of the genus Oestrum which are South American in origin, but are now cultivated as ornamental shrubs in various parts of the world, are reputed to contain alkaloids of the atropine type. They are known to have caused poisoning in stock (94) and their toxicity has been confirmed by experiment (95, 96).
