Astaxanthin (AST) and pycnogenol (PYC) are natural bioactive compounds commonly used in pharmaceuticals and functional foods due to their highly antioxidant activity and potential health benefits. However, the widespread application of astaxanthin is hindered by its poor water solubility and highly unsaturated structure. In this study, nanoparticles co-delivering astaxanthin and pycnogenol (NAP) were fabricated to enhance the dispersibility, stability, and bioavailability of astaxanthin.

The content of unsaturated fatty acids did differ between males and females of the two species studied. However, these differences are few and can be explained by the timing of their breeding seasons. The fatty acid composition of the fats from both investigated octopus species permits their use as food with nutritional value, and the production of bioactive additives.

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.
