The purple-stemmed jimson weed Datura tatula) is a somewhat taller plant, with purplish flowers and stems, but otherwise practically identical with the preceding, both in botanical and toxic characters. It is more abundant toward the South and West than the other. 

Artificially induced mutations have not yet yielded alkaloid-free plants. Ergots exposed to X-rays and ultraviolet radiation yielded some types which lacked pigment. Such leucosclerotia in general contained less alkaloid than the original forms (201, 232-235). Evans and Menendez (236) obtained Datura tatula L. D. stramonium L.) mutants in which the ratio of hyoscine to hyoscyamine was altered. Similar results have been reported by Mothes and associates (185) in which... 

The oxidation product has been isolated as its 2,4-dinitrophenylhydrazone and corresponds with -keto-6-aminovaleric acid. Putrescine, arginine, Manske s 1 (+) acetylornithine (118) and other related amino acids are oxidized much less readily if at all. The same authors have extracted an ornithine dehydrogenase from the young roots of Datura tatula. It requires the cooperation of a coenzyme not yet identified, and appears unable to oxidize putrescine and amino acids other than ornithine and to a lesser extent glutamic. Either of these systems, or the two linked into a H-transfer chain, would seem able to catalyze the oxidation of ornithine in the living tissues. No carbon dioxide was released from ornithine by the poly-phenolase system but on addition of an unwashed belladonna tissue-suspension carbon dioxide was liberated, presumably by decarboxylation of the a-keto-5-aminovaleric acid formed by the oxidation.

Datura tatula and Datura stramonium are Solanaceae plants from the North American continent, and now grow naturally in various places in Japan. Leaves of these plants are known as Datura leaves or Mandala leaves and contain (—)-hyoscyamine.They are used as materials for producing atropine sulfate.

Grafting on Datura stramonium roots a—Datura stramonium control on D. stramonium b—Datura tatula on D. stramonium c— Cyphomandra betacea on D. stramonium d—Nicotiana tabacum on D. stramonium. In all cases the aerial part (scion) accumulated tropane alkaloids like Datura stramonium, except in b, where the alkaloid hyoscyamine was converted into hyoscine.

The growth and alkaloid production of callus tissues of four Datura species, cultured in various media, have also been studied 13 the species investigated include D. stramonium, D. stramonium var. tatula (L) Torrey, D. stramonium L. var. godronii Danert, and D. innoxia Mill. Generally, the alkaloids formed were similar regardless of species, or of substances added to the culture medium atropine, scopolamine, tropine, apoatropine, and five unidentified alkaloids were detected by t.l.c. 

The genetic differences, if any, between Datura stramonium L. and D. tatula L. have been studied, with particular reference to their alkaloid content. There appears to be no difference between these species either in alkaloid content or in the kinds of alkaloids present in the leaves. Variations in alkaloid content were observed, however, in individual plants of interspecific hybrids, which seems to suggest some genetic differences in the parent species in those factors that affect alkaloid production. This confirms the accepted botanical view that D. stramonium and D. tatula should be regarded as two varieties of a single species. ...
