Biosynthesis and translocation of secondary metabolite glycosides in the grapevine Vitis vinifera L. / by Mansour Gholami.

Gholami, Mansour January 1996 (has links)
Copies of author's previously published articles inserted. / Bibliography: leaves 121-144. / xiii, 150 leaves : ill. (chiefly col.) ; 30 cm. / Title page, contents and abstract only. The complete thesis in print form is available from the University Library. / This study investigates the site of biosynthesis of flavour compounds in the grapevine. Most of the secondary metabolites, including flavour compounds, are glycosylated and stored in plant tissues as glycosides. The chemical properties of these compounds, especially their water solubility, suggests that glycosides might be forms of translocated secondary metabolites in plants. / Thesis (Ph.D.)--University of Adelaide, Dept. of Horticulture, Viticulture and Oenology, 1996?

Application of a particle filtration method in the search for new bioactive natural products from fungi

Yusof, Mohd Termizi Bin January 2008 (has links)
Fungi have been an important source for producing a wide range of secondary metabolites of widely differing chemical structures, as well as biological activities. Many of their metabolites now play a major role in pharmaceutical and agricultural industries. A number of fungi were isolated from soil and leaf litter collected from Arthur’s Pass, West Coast and Kaituna Valley using a particle filtration technique. Fungi were selected based on their unusual morphology or observed cytotoxicity and antimicrobial activity for large scale culture and extraction. A pale yellow compound was isolated from cytotoxic extracts from the culture of Aspergillus versicolor. This compound was identified as sterigmatocystin and the identity confirmed by UV profile and mass spectrometry. Five compounds were isolated from extracts prepared from two different species of Penicillium of which three were active against P388 cells (mycophenolic acid, cycloaspeptide A and mevastatin), one was active against dermatophytes (griseofulvin) and one was not active (3,4,6,8-tetrahydroxy-3-methyl-3,4-dihydroisocoumarin). Two compounds were isolated from extracts prepared from two different species of Phoma. A dark red compound was found to be novel and showed activity against P388 cells and Bacillus subtilis. A second compound also showing cytotoxicity was identified as the known compound phomenone. A further new compound was isolated from extracts of an identified dematiaceous fungus. This alkyl glucoside, however, was not bioactive.

Application of selective methods in the search for new bioactive natural products from fungi

Chamyuang, Sunita January 2010 (has links)
The work undertaken explored the potential for discovery of new bioactive metabolites from soil fungi. The research developed selective mycological isolation techniques and maximised metabolite production from active selected fungi by application of the OSMAC approach and concept of hormesis. Novel active compounds were discovered and many other known compounds characterised.
