Duboisia myoporoides Solanaceae

The most recent work, by Gritsanapan and Griffin (1991), extended the range of study to more northerly sites in Queensland and included populations at different elevations. Four sites were studied (1) northern Queensland at elevation lOOOm

The simple piperidine pelletierine from Punica granatum (pomegranate) (Punicaceae) and Duboisia myoporoides (Solanaceae) is an anthelmintic. The simple piperidine derivatives deoxy-mannojirimycin (DMJ) and deoxynojirimycin (DNJ) from Lonchocarpus species (Fabaceae) are glycosidase inhibitors because they are structurally similar to the pyranose (six-membered ring) sugar moieties of the glycosidase disaccharide substrates. 

Tropine derivatives are typically found in certain highly poisonous Solanaceae species, most notably Atropa belladonna (deadly nightshade), Datura stramonium (thornapple), other Datura species, Duboisia myoporoides (corkwood elm), Hyoscyamus niger (henbane) and other Hyoscyamus species. Other sources include Convolvulus species (Convolvulaceae), Erythroxylum coca (coca), other Erythroxylum species (Erythroxylaceae) and Bruguiera species (Rhizophoraceae).

Genus Duboisia (Family Solanaceae) comprises four species, Duboisia leichhardtii F. Muell, D. myoporoides R. Br., D. hapwoodii F. Muell and recently discovered D. arenitensis L. A. Craven, B. J. Lepschi L. A. R. Haegi, and the leaves of D. leichhardtii and D. myoporoides, as well as... 

The Australian species Duboisia myoporoides R.Br., family Solanaceae, is a bush-tree, which grows on the east coast of Australia, New Caledonia and adjacent islands. Its leaves contain about 2% alkaloids. Leaves harvested in October contain hyo-scyamine as the main alkaloid, whereas leaves harvested in April have scopolamine as the main alkaloid. (Fig. 3)...

Alkaloid from Duboisia myoporoides, N. glauca and other spp. (Solanaceae). BP775 280-282°. 

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.
