Abstract:

The taxonomic status of the fungal genus <i>Endothia</i> was recently changed in a controversial monograph by Barr (Barr, M. E. 1978. The Diaporthales of North America. Mycol. Mem. 7. J. C. Cramer. 232 p.), who divided the genus into two separate genera, <i>Endothia</i> and <i>Cryphonectria</i>, based on differences in ascospore shape and septation, stromatic configuration and distribution of stromatic tissues. This group of fungi traditionally contains some important plant pathogens; its taxonomic position needs to be resolved. The morphological criteria used by Barr were reinvestigated. Poly

Abstract:

A chemotaxonomic identification of the herbal remedy Chrysanthemum parthenium (feverfew) and its reported adulterants Chrysanthemum vulgaris (tansy) and Chamomile vulgaris (German chamomile) has been undertaken. An initial survey investigated the distribution of phenolic compounds in the plants using a RP-HPLC diode-array system. A chemometric analysis of the data distinguished feverfew from its adulterant German chamomile, though tansy was ambiguous. In the light of these findings, the GLC of essential oils and in particular the reported active ingredient parthenolide, were used as alternativ

Abstract:

The Proteaceae is a flowering plant family containing approximately 1700 species across more than 80 genera and is a predominant feature of Australian and South African flora. The chemistry of plants from the family has been studied by researchers for over a century but these studies have neither been systematic nor extensive. The research carried out in this thesis has firstly systematically reviewed and synthesized the current state of knowledge with regard to the natural products chemistry of the Proteaceae in relation to taxonomic groupings derived from molecular and morphometric phylogene

Abstract:

De nombreuses biomolécules qui constituent les plantes vasculaires ne sont synthétisées que par certains taxons de plantes et ont donc une spécificité chimiotaxonomique. Certaines d'entre elles, tels que les bioterpénoïdes, sont particulièrement résistantes et sont préservées dans les sédiments où elles se transforment en géoterpénoïdes lors de la diagenèse. Ces géoterpénoïdes conservent, partiellement ou totalement, leur spécificité initiale (spécifité paléochimiotaxonomique). Cependant, nos connaissances actuelles en paléochimiotaxonomie botanique, qui permettent d'associer ces biomarqueurs

Abstract:

This thesis represents an exploratory and iterative study into the relationships of Australian native plants from the family Myrtaceae, with respiratory symptoms, specifically asthma. This relationship is explored from a chemo-taxonomic stance and the connections with other plants with related chemotaxonomy are underlined. The research was performed against a background of geographical comparison between an urban coastal area and a rural mountainous area 90 kilometres just north of Brisbane, Queensland, Australia. The focus was the possible contribution of Melaleuca quinquenervia to the occurr

Abstract:

A study was undertaken of plants used for treatment of diabetic symptoms by traditional healers of the Eeyou Istchee Cree (Canada), Lukomir Highlanders (Bosnia & Herzegovina), and Q’eqchi’ Maya (Belize). All antidiabetic plants were ranked by syndromic importance value (SIV) based on 15 symptoms, all of which were recognized by the Cree and Maya and 8 by the Highlanders. The Cree used only 18 species, the Highlanders 41, and the Maya 150, numbers which reflect the diversity of flora in their region. Vaccinium (Ericaceae) was one of the few genera in all three regions and the only consensus gen

Abstract:

This thesis reports on the application of a rapid and simple pressurised hot water extraction (PHWE) method that utilises an unmodified household espresso machine to extract structurally-diverse natural products from plant material. The core focus of this thesis was the use of PHWE to expedite phytochemical screening of native Tasmanian and Australian plants and facilitate natural product isolation. The introduction features reviews on two key topics that are pertinent to the research described in this thesis. The first review summarises all natural product isolation studies of endemic Tasman

Abstract:

Ph.D.<br>This chemotaxonomic study of the leaf phenolic compounds in the genus Aloe is introduced by presenting a review of Aloe taxonomy, followed by a second review of all known leaf compounds. A chemotaxonomic study of virtually all species of Aloe has made it possible to define several chemical groups in the genus of 420 species. The chemical groups are either identified by a single marker compound or by a series of unique compounds. The following groups have been identified and the chemotaxonomic value of each group is discussed: • An aloin / aloinoside / microdontin group, comprising 36

Abstract:

In this PhD thesis, a comprehensive phytochemical analysis was performed on a series of nineteen plants belonging to the Lamiaceae family. In particular, five Ajuga, three Teucrium, one Galeopsis, two Melittis, two Sideritis and six Stachys species were studied for their content in secondary metabolites in the polar fraction. One hundred and sixty-nine compounds were, respectively, isolated and identified by these species mainly by means of Column Chromatography and by means of NMR Spectroscopy and MS Spectrometry. These phytochemicals belong to thirteen different classes of natural compoun
