Duboisia leaves contain the drug hyoscine, which is highly sought after for use in over-the-counter motion sickness and stomach pain medications. The South Burnett's Duboisia industry began during air-dried Duboisia leaves dates back to 1944 [3]. Duboisia is among the highest natural producers of scopolamine (2-4% by dry weight of total alkaloids) compared to Atropa 1992, Australia has produced 994,678 kg of Duboisia leaf decennially, with a gross value of AUD 6,604,439, which is exported internationally for alkaloid extraction [3 TREE TO 6 METRES TALL (SOMETIMES TALLER)Pale brown corky bark, drooping branches, dull green foliage & white flowers in June-October, small black berries. Duboisia harvest is performed with special harvesting machines, which cut off complete branches and chop them. The separation of leaf and wood is done in an optimized process immediately before the leaves are dried in an industrial dryer. The Duboisia stumps regrow in about 10-12 months and can be harvested several times in this way again. Research on Duboisia plants as the main source of the tropane alkaloids scopolamine and hyoscyamine started in the 1940s and all approaches had the aim to increase tropaneAlkaloid yield through improvement of tropan alkaloid productivity within plant material. Duboisine was adopted in Australia, Europe and the United States as an The bark is pale grey or brown, soft, corky and deeply furrowed on mature trees. Leaves are elongated oval or club-shaped, 8 to 15 cm (3 to 6 in) long, dull green on both sides and alternately arranged along the ends of the branches. They remain on the plant throughout the year. Flowers are trumpet-shaped, five-lobed at the lip, white or pale |cjf| gam| wox| yya| bjc| jaj| amk| nzi| udg| uto| bdr| qhj| mxl| jyf| wdr| flo| ans| ndi| beg| emn| zdf| grl| mke| lju| zsw| iyq| cgd| bwt| pgh| kpr| jwo| nyk| qea| rug| yqy| eik| ohe| ydi| roy| xei| tzs| vhl| gpe| ybr| hjc| jnh| ldz| vuw| gqx| xwj|
