Overview
Ali Ali Redha is a PhD student at the QUEX Institute (The University of Queensland and the University of Exeter) under the supervision of Dr Luciana Torquati (UoE), Prof Mike Gidley (UQ), Prof Geoff Nash (UoE), and Dr Daniel Cozzolino (UQ).
His PhD project focuses on improving the bioavailability of health-promoting bioactive compounds present in vegetables. It involves developing green analytical techniques for quick determination of bioactive compounds using infrared spectroscopy that could be used in the food industry to monitor and optimise different post-harvest treatments to ensure conserving the highest amount of bioactive compounds. The project also involves applying encapsulation methods to protect sensitive bioactive compounds to improve their bioaccessibility and bioavailability.

Abstract:
Anti-Depressant Properties of Crocin Molecules in Saffron
Saffron is a valued herb, obtained from the stigmas of the C. sativus Linn (Iridaceae), with therapeutic effects. It has been described in pharmacopoeias to be variously acting, including as an anti-depressant, anti-carcinogen, and stimulant agent. The therapeutic effects of saffron are harbored in its bioactive molecules, notably crocins, the subject of this paper. Crocins have been demonstrated to act as a monoamine oxidase type a and B inhibitor. Furthermore, saffron petal extracts have experimentally been shown to impact contractile response in electrical field stimulation. Other research suggests that saffron also inhibits the reuptake of monoamines, exhibits N-methyl-d-aspartate antagonism, and improves brain-derived neurotrophic factor signaling. A host of experimental studies found saffron/crocin to be similarly effective as fluoxetine and imipramine in the treatment of depression disorders. Saffron and crocins propose a natural solution to combat depressive disorders. However, some hurdles, such as stability and delivery, need to be overcome.
