The Duboisia Genus, Australian Aborigines and Suggestibility The Duboisia Genus, Australian Aborigines and Suggestibility Marlene Dobkin de Rios, Ph.D: & Ronni Stachalek, M.A:* Abstract-Plant hallucinogens, such as those of the Duboisia genus called pituri, have been used by tribal elders in Australian aboriginal populations to create managed states of consciousness, to provide their youth with a' fast-paced educational experience, and to inculcate values, beliefs and religious tenets. Use of the suggestible states created by such substances (particularly in pubertal initiatory rituals marking the transition to manhood) are part of this process, which contributes to cultural cohesiveness and survival; their effectiveness is due to the unique ability of the biochemical properties of the plant to evoke suggestibility in those who ingest them. This article draws on research about suggestibility as a psychological characteristic of altered states of consciousness as well as a normal human psychological phenomenon, and examines in great detail the use of the pituri plant, deriving data from a 100-item bibliography generated by the Australian Institute of Aboriginal and Torres Strait Islander Studies in Canberra. Botanical/chemical data on use of the Duboisia genus up to the end of the nineteenth century is examined, as well as the way in which this hallucinogen was utilized as a "psychotechnology."

  • Appendix Color Plates of Solanales Species
    Appendix Color Plates of Solanales Species The first half of the color plates (Plates 1–8) shows a selection of phytochemically prominent solanaceous species, the second half (Plates 9–16) a selection of convol- vulaceous counterparts. The scientific name of the species in bold (for authorities see text and tables) may be followed (in brackets) by a frequently used though invalid synonym and/or a common name if existent. The next information refers to the habitus, origin/natural distribution, and – if applicable – cultivation. If more than one photograph is shown for a certain species there will be explanations for each of them. Finally, section numbers of the phytochemical Chapters 3–8 are given, where the respective species are discussed. The individually combined occurrence of sec- ondary metabolites from different structural classes characterizes every species. However, it has to be remembered that a small number of citations does not neces- sarily indicate a poorer secondary metabolism in a respective species compared with others; this may just be due to less studies being carried out.

The culturing of Duboisia sp., although very important for world medicine, has been poorly studied in the field, since the cultivation of this plant is restricted to a few regions. The objective of this paper is to characterize growth and nutrient absorption during development in Duboisia sp. under a commercial cultivation system, and in particular to assess the distribution of dry matter and nutrients in the leaves and branches. Our work was performed on a commercial production farm located in Arapongas, Paraná, Brazil, from March 2009 to February 2010. A total of 10 evaluations took place at approximately 10-day intervals, starting 48 days after planting and ending at harvesting, 324 days after planting.

A phylogeny of Solanaceae is presented based on the chloroplast DNA regions ndhF and trnLF. With 89 genera and 190 species included, this represents a nearly comprehensive genus-level sampling and provides a framework phylogeny for the entire family that helps integrate many previously-published phylogenetic studies within So- lanaceae. The four genera comprising the family Goetzeaceae and the monotypic families Duckeodendraceae, Nolanaceae, and Sclerophylaceae, often recognized in traditional classifications, are shown to be included in Solanaceae. The current results corroborate previous studies that identify a monophyletic subfamily Solanoideae and the more inclusive “x = 12” clade, which includes Nicotiana and the Australian tribe Anthocercideae. These results also provide greater resolution among lineages within Solanoideae, confirming Jaltomata as sister to Solanum and identifying a clade comprised primarily of tribes Capsiceae (Capsicum and Lycianthes) and Physaleae.

Email: [email protected] Alkaloids derived from solanaceous plants were the subject ofintense investigations by European chemists, pharmacologi~ts and clinicians in the second half ofthe nineteenth century. Some surprise was expressed when it was discovered in the 1870s that an Australian bush, Duboisia myoporoides, contained an atropine­ like alkaloid" 'duboisine'. A complicated and colourful history followed. Duboisine was adopted in Australia, Europe and the United States as an alternative to atropine as an ophthalmologic agent; shortly afterwards, it was also estecmed as a potent sedative in the management ofpsychiatric patients, and as an alternative to other solanaceous alkaloids in the treatment ofparkinsonism. The Second World War led to renewed interest in Duboisia species as sources of scopolamine, required for surgical anaesthesia and to manage sea-sickness, a major problem in the naval part ofthe war. As a consequence ofthe efforts of the CSIR and of Wilfrid Russell Grimwade (1879-1955), this led to the establishment of plantations in Queensland that today still supply the bulk of the world's raw scopolamine. Following the War, however, government support for commercial alkaloid extraction waned, and it was the interest ofthe German firm Boehringer Ingelheim and its investment in the industry that rescued the Duboisia industry in the mid­ I950s, and that continues to maintain it at a relatively low but stable level today.

Pleurothallis cerea, a species described based on a specimen collected by Lankester in Costa Rica, and commonly placed under the synonymy of Myoxanthus octomeriae or M. congestus, is here recognized as distinct. The species is easily distinguished by the shape and size of the leaf, as well as various floral details, especially of the lip. A new combination, tentatively suggested by Carl Luer but never published, is required and therefore validated. Additionally, the vegetatively striking Myoxanthus affinis is recorded from Costa Rica for the first time based on two recent collections.

  • Duboisia Leichhardtii (F.Muell.) Extracts Inhibit the Growth of Bacterial Triggers of Selected Autoimmune Inflammatory Diseases
    Pharmacogn J. 2016; 8(6): 542-550 A Multifaceted Journal in the field of Natural Products and Pharmacognosy Original Article www.phcogj.com | www.journalonweb.com/pj Duboisia leichhardtii (F.Muell.) Extracts Inhibit The Growth of Bacterial Triggers of Selected Autoimmune Inflammatory Diseases Ian Edwin Cock1,2 ABSTRACT Introduction: Duboisia leichhardtii F.Muell. is a medium to large tree which is native to subtropical regions of eastern Australia. Duboisia spp. contain a number of psychoac- tive tropane and pyrrolidine alkaloids with reported antibacterial activity. Despite this, D. leichhardtii leaf extracts have not been rigorously examined for growth inhibitory properties against many bacteria, including the bacterial triggers of autoimmune inflammatory diseases. Methods: The antimicrobial activity of D. leichhardtii leaf solvent extracts was investigated by disc diffusion and growth time course assays against a panel of bacterial triggers of autoimmune diseases. The growth inhibitory activity was further quantified by MIC determination and growth time course assays. Toxicity was determined using the Artemia franciscana nauplii bioassay. Results: Methanolic and aqueous D. leichhardtii leaf solvent extracts were potent inhibitors of the bacterial triggers of rheumatoid arthritis and ankylosing spondylitis. The methanolic extract displayed the most potent bacterial growth inhibitory activity. It was particularly potent against P. mirabilis (MICs of 85 and 116 µg/mL against reference and clinical strains respectively) and P. vulgaris (MIC of 187 µg/mL). The methanolic extract was also a good inhibitor of K. pneumoniae growth (MICs of 143 and 118 µg/mL against reference and clinical strains respectively). The aqueous and ethyl acetate extracts were also potent bacterial growth inhibitors, albeit with higher MIC values.
