Abstract Conventional techniques for identifying antioxidant and phenolic compounds in native Australian food plants are laborious and time-consuming. Here, we present a multiplexed detection technique that reduces analysis time without compromising separation performance. This technique is achieved using Active Flow Technology-Parallel Segmented Flow AFT-PSF columns. Extracts from cinnamon myrtle Backhousia myrtifolia and lemon myrtle Backhousia citriodora leaves were analysed via multiplexed detection using an AFT-PSF column with underivatised UV-VIS, mass spectroscopy MS, and the 2,2-diphenyl-1-picrylhydrazyl DPPH• derivatisation for antioxidants as detection methods. A number of antioxidant compounds were detected in the extracts of each leaf extract. View Full-Text
