We thank Samdanjigmed Tulganyam, James Hamilton and Altantsetseg Balt (OT) for their active engagement with the project and useful insights. The project was supported by Wildlife Conservation Society, Mongolia Country Program (WCS), and we especially thank Enkhtuvshin Shiilegdamba (Acting Director) and Dashzeveg Tserendeleg (Extractive Industry Manager) for their support. The work depended on the generosity of over 90 stakeholders, each of whom gave several hours of their time to contribute. We are greatly appreciative of their efforts. The Mongolian field work and workshops were greatly assisted by logistical and expert botanical assistance from Bolor-Erdene Lkhamsuren, Onon Bayasgalan and Tsolmon Jambalsuren (WCS). Discussion with David Wilson (Global Biodiversity Conservation) and Stuart Anstee (Stuart Anstee & Associates) greatly improved our understanding of the context of the project. The video used to facilitate international participation was filmed by Fern Hames (ARI). The project also benefitted from the support of Kim Lowe, Tim O’Brien, Graeme Newell and Matthew Bruce at ARI.

  • Are Supplements Supplemented? Evaluating the Composition of Complementary and Alternative Medicines Using Mass Spectrometry and Metabolomics
    Are supplements supplemented? Evaluating the composition of complementary and alternative medicines using mass spectrometry and metabolomics By Elly Gwyn Crighton BForensics in Forensic Biology & Toxicology (First Class Honours) BSc in Molecular Biology & Biomedical Science This thesis is presented for the degree of Doctor of Philosophy Perth, Western Australia at Murdoch University 2020 Declaration I declare that: i. The thesis is my own account of my research, except where other sources are acknowledged. ii. The extent to which the work of others has been used is clearly stated in each chapter and certified by my supervisors. iii. The thesis contains as its main content, work that has not been previously submitted for a degree at any other university. i Abstract The complementary and alternative medicines (CAM) industry is worth over US$110 billion globally. Products are available to consumers with little medical advice; with many assuming that such products are ‘natural’ and therefore safe. However, with adulterated, contaminated and fraudulent products reported on overseas markets, consumers may be placing their health at risk. Previous studies into product content have reported undeclared plant materials, ingredient substitution, adulteration and contamination. However, no large-scale, independent audit of CAM has been undertaken to demonstrate these problems in Australia. This study aimed to investigate the content and quality of CAM products on the Australian market. 135 products were analysed using a combination of next-generation DNA sequencing and liquid chromatography-mass spectrometry. Nearly 50% of products tested had contamination issues, in terms of DNA, chemical composition or both. 5% of the samples contained undeclared pharmaceuticals.

Herbs perennial, bulbiferous, sometimes with well-developed, thick or thin rhizomes, rarely with stolons or tuberous roots, usually with onionlike, leeklike, or garliclike odor when fresh. Bulb covered with a tunic. Leaves sessile, very rarely narrowed into a petiole, with a closed leaf sheath at base, linear, linear-lanceolate, or lorate to orbicular-ovate, cross section flat, angled, or semiterete to terete, fistulose or solid. Scape terminal or lateral, sheathed or naked. Inflorescence a terminal umbel, sometimes with bulblets, rarely flowerless and with bulblets only, enclosed in a spathelike bract before anthesis. Pedicels with or without basal bracteoles. Flowers bisexual, very rarely degenerating into unisexual (when plants dioecious). Perianth segments free or united into a tube at base. Filaments usually connate at base and adnate to perianth segments, entire or toothed. Ovary with 1 to several ovules per locule; septa often containing nectaries opening by pores at base of ovary. Style simple; stigma entire or 3-cleft. Capsule loculicidal. Seeds black, rhomboidal or spheroidal. About 660 species: N hemisphere, mainly in Asia, some species in Africa and Central and South America; 138 species (50 endemic, five introduced) in China. Most Eurasian species have the base chromosome number x = 8, whereas North American species predominantly have x = 7. Nearly all species with x = 10 and 11 occur in SW China. Most species of Allium are edible, and some have long been cultivated in China and elsewhere, e.g., A.
