This history of antimicrobials is marked with impressive discoveries, the majority of which have their origin in natural products. However in this work, the antimicrobial activity of β- nitrostyrenes and related compounds of synthetic origin is reviewed and investigated with a particular focus on the influence of fluorine functionality. Various fluorinated β-methyl-β-nitrostyrene compounds were prepared, their minimum inhibition concentration in cultures of Gram positive, Gram negative and a fungus and their lipophilicity was determined.

This thesis documents a research program in which Australian grown Danshen extracts and related bioactive compounds have been demonstrated to be effective in scavenging free radicals, namely ROS generation, in a cell free system and NADPH oxidase derived superoxide (O2-) generation in vascular tissue (rat aorta). Danshen extracts, both aqueous and ethanol, and their active compounds (Tanshinone IIA, Salvianolic Acid B and Danshensu) demonstrated anti-oxidant activity however findings exhibited stronger activity in a cell free system than in the aortic vascular tissue.

The focus of this thesis was to study the chemotaxonomic relationship of selected southern Australian marine brown algae of the genera Cystophora and Sargassum. Consequently, this resulted in the isolation and structure elucidation of six new terpenoids from two southern Australian marine brown algae Cystophora moniliformis and Sargassum fallax together with 10 previously reported natural products. As a result of the re-isolation of these known secondary metabolites, updated and complete structural characterisation data could be provided for the first time for 7 of these compounds.

As science and technology has developed, the manner by which drugs can be delivered has grown. Medicines may be taken orally, applied as topical pastes, creams or oils, patches or administered by direct injection to the body. This research explores an alternative method for the delivery of therapeutic compounds to the body. The basis of the study involves the application of traditional medicinal compounds used to cure minor neck and back pains through transdermal topical application, using a textile substrate as the carrier.

Municipal wastewater treatment plants generally utilise biological activated sludge processes to remove organic compounds and nitrogen. The biological nitrogen removal (BNR) occurs in two steps, nitrification (ammonium removal) and denitrification (nitrates removal). This study focused on a medium-sized wastewater treatment plant (WTP) which experienced poor nitrification for years, mainly when the weather temperature drops.

This study examined the effectiveness of different antioxidative compounds, namely 0.2% BHA (Butylated hydroxyanisole) + BHT (butylated hydroxytoluene), 0.03% α – tocopherol, and 3% and 6% tea seed oil (TSO) on the oxidative stability of vegetable oils. Four commonly used oils, viz. rapeseed oil (RSO), peanut oil (PNO), sunflower oil (SFO), and soybean oil (SBO), were assessed by the Schall Oven test method and monitored during the 12-day preservation period under 60°C.
