Detailed APCI-QTOF-HRMS analyses enabled a highly accurate detection of the most abundant ion species and respective signal intensity ratios of retro-carotenoids, facilitating their further screening and reliable identification in natural sources. Mass fragmentations of the studied retro-carotenoids were found to be substantially impacted by the extraordinary configuration of their polyene backbone.
