Humboldt and Bonpland, who collected Datura sanguinea on the banks of the Rio Mayo, in New Granada, state that the natives believe that the tonga prepared from this species to be more efficacious as a narcotic than that made from the white-flowered Datura arborea mentioned above. It is from the account of these travelers that the story of the Peruvian prophets is taken. The Temple of the Sun in which they officiated was at Sagamoza, in the interior of what is now Colombia. Dr. Santiago Cortes, in his account of the medicinal plants of the province of Cauca, Colombia, says that there are many stories and fables relating to this plant told by the natives. 

Naturally occurring hyoscine is a combination of laevo-tropic acid with inactive hyoscine. It is found, mostly in conjunction with hyoscyamine, in many species of Datura. In D. arborea, D. fastuosa, and D. metel, the alkaloid consists chiefly of hyoscine whilst D. stramonium contains principally hyoscyamine, with some hyoscine. It is present also in Scopolia and Hyoscyamus species, for instance in Scopolia japonica and Hyoscyamus niger.

Brugmansia/Datura. Floral VOCs of two Brugmansia spp. [B. arborea (L.) Lagerh. sub nom. D. arborea (L.), B. Candida Pers. sub nom. D. Candida (Pers.) Safe.] and three Datura spp. [D. inoxia Mmc., D. metel L., D. stramonium L.] were analyzed by Kawashima (1996). The results showed rich blends of monoterpenes (e.g., ocimene, pinenes, Umonene, sabinene) and oxidized congeners including esters (e.g., linalool, linalyl acetate, citroneUol, nerol, neryl acetate, neral, geraniol, geranyl formate, camphor, carvone, 1,8-cineol, fenchol) (Fig. 7.2) beside members of different classes of metabolites (e.g., phenylpropanoids, fatty acid esters), but almost no sesquiterpenes.
