The research is focused on the structure of anthocyanins in red cabbage. 

Anthocyanins are a subclass of plant-derived flavonoids that demonstrate immense structural heterogeneity which is challenging to capture in complex extracts. River and the team explore direct injection ion mobility-mass spectrometry as a rapid analytical tool to characterize anthocyanin structural features in red cabbage. Direct injection ion mobility-mass spectrometry provides wholistic structural information on structurally similar, and even isobaric, anthocyanins in complex plant extracts, which can inform the nutritional value of a plant and bolster drug discovery pipelines.
