Visualization of Asparaptine in Asparagus (Asparagus Officinalis) Using Mass Spectrometry Imaging

Introduction

With functional foods attracting attention in recent years, it has been suggested that asparagus suppresses blood pressure elevation. Asparaptine, a component included in asparagus, is associated with this, but no information about the localization of this component has been revealed. We therefore clarified the location of asparaptine within asparagus by using the technology of matrix-assisted laser desorption/ionization - mass spectrometry imaging (MALDI-MSI).
