Visualizing the spatial distribution and alteration of metabolites in continuously cropped Salvia miltiorrhiza Bge using MALDI-MSI.

ABSTRACT: Salvia miltiorrhiza Bge (SMB) has long been used in traditional Chinese medicine to treat cardiovascular and cerebrovascular diseases. Growing clinical usage has led to a huge demand for artificial planting of SMB. Thus, continuous cropping of SMB is an important challenge that needs to be addressed. Continuous cropping can alter the metabolic profile of plants, resulting in poor growth and low yield. In this study, we tried to image the spatial location and variation of endogenous metabolites in continuously cropped SMB using matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI). Spatially resolved expressions of tanshinones, salvianolic acids, polyamines, phenolic acids, amino acids, and oligosaccharides in normal and continuously cropped SMB roots were
